Abstract:
Algoritma ElGamal merupakan algoritma dalam kriptografi yang termasuk dalam kategori algoritma asimetris. Keamanan algoritma ElGamal terletak pada kesulitan penghitungan logaritma diskret pada bilangan modulo prima yang besar sehingga upaya untuk menyelesaikan masalah logaritma ini menjadi sangat sukar. Algoritma ElGamal terdiri dari tiga proses, yaitu proses pembentukan kunci, proses enkripsi dan proses dekripsi. Proses pembentukan kunci kriptografi ElGamal terdiri dari pembentukan kunci privat dan pembentukan kunci public. Pada proses ini dibutuhkan sebuah bilangan prima aman yang digunakan sebagai dasar pembentuk kunci public sedangkan sembarang bilangan acak digunakan sebagai pembentuk kunci privat. Pada penelitian sebelumnya digunakan bilangan prima aman pada proses pembentukan kunci namun tidak dijelaskan alasan mengapa harus menggunakan bilangan prima aman tersebut. Penelitian ini mencoba membandingkan penggunaan bilangan prima aman dan bilangan prima tidak aman pada pembentukan kunci algoritma elgamal. Analisa dilakukan dengan mengenkripsi dan dekripsi sebuah file dengan memvariasikan nilai bilangan prima aman dan bilangan prima tidak aman yang digunakan untuk pembentukan kunci public dan kunci privat. Dari hasil analisa dapat disimpulkan bahwa dengan menggunakan bilangan prima aman maupun bilangan prima tidak aman, proses pembentukan kunci, enkripsi dan dekripsi tetap dapat berjalan dengan baik, semakin besar nilai bilangan prima yang digunakan, maka kapasitas cipherteks juga semakin besar.Elgamal algorithm is an algorithm in cryptography that is included in the category of asymmetric algorithms. The security of Elgamal algorithm lies in the difficulty in calculating the discrete logarithm on large number of prime modulo that attempts to solve this logarithm problem becomes very difficult. Elgamal algorithm is consists of three processes, that are the key generating, encryption and decryption process. Key generation of elgamal cryptography process is consisted of the formation of the private key and public key. In this process requires a secure prime number is used as the basis for forming public key while any random number used as forming of the private key. In the previous research is used secure prime number on key generating process but does not explain the reasons of using the secure primes. This research tried to compare using secure and unsecure primes in elgamal key generating algorithm. The analysis is done by encrypting and decrypting a file by varying the value of secure and unsecure of prime numbers that are used on generating of a public and a private key. From the analysis it can be concluded that using secure and unsecure of prime numbers, the process of key generating, encryption and decryption can run well, the greater value of prime numbers are used, the greater the capacity of the ciphertext.

Abstract:
Internet of Things (IoT) memungkinkan suatu objek menghasilkan data dan bertukar data. Pengaplikasian IoT menggunakan mikrokontroler seperti Arduino belum memiliki fitur untuk menjaga keamanan data di dalamnya. Selain itu, Arduino memiliki kapabilitas komputasi terbatas. Oleh karena itu, perlu diterapkan kriptografi dengan algoritme yang memiliki komputasi rendah pada Arduino untuk menjaga keamanan data. Penjagaan keamanan data terutama pada keaslian asal data, dilakukan dengan menggunakan tanda tangan digital. Penerapan tanda tangan digital dapat dilakukan salah satunya dengan algoritme Elgamal signature scheme. Penerapan tanda tangan digital menggunakan algoritme Elgamal signature scheme berhasil diterapkan pada perangkat Arduino Uno untuk melakukan tanda tangan digital dan verifikasi. Kinerja algoritme Elgamal signature scheme dilihat dari analisis waktu eksekusi dan analisis keamanan algoritme. Waktu eksekusi proses tanda tangan digital membutuhkan waktu lebih lama dibandingkan dengan waktu eksekusi proses verifikasi. Algoritme Elgamal signature scheme membutuhkan waktu dua kali lebih lama karena banyaknya perhitungan sistematis pada perangkat Arduino Uno. Proses verifikasi terbukti gagal jika ada perubahan data dan pasangan tanda tangan digital.
 Kata Kunci: Arduino, Elgamal signature scheme, internet of things, kriptografi, tanda tangan digital.

Abstract:
Perkembangan Teknologi pada saat ini memungkinkan setiap orang untuk saling bertukar informasi tanpa ada batasan waktu dan jarak. Kemungkinan yang akan terjadi adanya kebocoran data pada saat proses pertukaran informasi yang dilakukan, oleh karena itu dalam pengiriman data khususnya citra, aspek keamanan, kerahasiaan dan efesiensi penyimpanan data sangat diperlukan. Jika informasi penting tersebut jatuh ke tangan orang yang salah, maka akan menyebabkan hal yang tidak diinginkan, contohnya manipulasi gambar dengan bentuk yang negatif dan dapat merugikan pemilik gambar. Salah satu metode yang digunakan untuk menjaga keamanan data tersebut adalah kriptografi dengan menggunakan salah satu teknik yaitu Elgamal. Kekuatan algoritma ini terletak pada sulitnya menghitung algoritma diskrit pada bilangan bulat prima yang didalamnya dilakukan operasi pekalian. Dalam penelitian ini, penulis menggabungkan antara Hill Cipher untuk melakukan penyandian enkripsi citra dan Algoritma Elgamal untuk mendekripsi kunci dari Hill Cipher. Citra pertama kali dienkripsi menggunakan Hill Cipher, kemudian kunci Hill Cipher tersebut dienkripsi dengan menggunakan Algoritma Elgamal. Implementasi sistem menggunakan bahasa pemograman Visual Basic Net 2010. Hasil implementasi dengan citra awal dienkrip memiliki waktu 4282.85 Milidetik dengan hasil gambar yang beracak-acak sedangkan citra yang sudah dienkrip akan kembali di deskripsikan yang memiliki waktu 20442.84 Milidetik dengan hasil citra kembali ke awal.

Abstract:
The development of technology at this time allows everyone to exchange information without any limitation of time and distance. The possibility that data leakage will occur during the process of exchanging information is carried out, therefore in sending data especially images, security aspects, confidentiality and efficiency of data storage is very necessary. If the important information falls into the wrong hands, it will cause unwanted things, for example manipulation of images with negative shapes and can harm the owner of the image. One method used to maintain data security is cryptography using one of the techniques, Elgamal. The strength of this algorithm lies in the difficulty of calculating discrete algorithms on prime integers in which multiplication operations are performed. In this research, the writer combines Hill Cipher to do image encryption and Elgamal Algorithm to decrypt the key of Hill Cipher. The image is first encrypted using the Hill Cipher, then the Hill Cipher key is encrypted using the Elgamal Algorithm. The implementation of the system uses the programming language Visual Basic Net 2010. The results of the implementation with the initial encrypted image has 4282.85 milliseconds with random images, while the encrypted image will be re-described as having 20442.84 milliseconds with the image returned to the beginning.

Abstract:
Encryption is a well known technology for protecting sensitive data. ElGamal encryption and RSA algorithm is made before storing mails to mail server. ElGamal decryption and RSA decryption is made after retrieving mails from mail server. This system is implemented to secure mail server system for local government’s important mail messages. These algorithms consume a considerable amount of time and resources such as memory, CPU time, and computation time to encrypt and decrypt data. In this paper, the results are comparison of these algorithms in term of encryption time, decryption time, and memory usage over variable file sizes. After processing, it is proven that RSA performs a faster encryption process than ElGamal. However, ElGamal decryption process is faster than RSA. This system is also expressed comparison of storage Size between RSA and ElGamal. Both of these algorithms are cryptographic public-key algorithms but have functions in different ways. This system is using C# programming language and SQL Server to store mail messages.

<em>Keamanan data merupakan hal yang sangat penting dalam menjaga kerahasiaan informasi terutama yang berisi informasi sensitif yang hanya boleh diketahui isinya oleh pihak yang berhak saja, apalagi jika pengirimannya dilakukan melalui jaringan publik, apabila data tersebut tidak diamankan terlebih dahulu, akan sangat mudah disadap dan diketahui isi informasinya oleh pihak-pihak yang tidak bertanggung jawab. Oleh karena itu peneliti merekomendasikan algoritma Elgamal untuk dapat memberikan keamanan pada text dan docx, algoritma ElGamal adalah merupakan bagian dari kriptografi asimetris yang pembentukan salah satu kuncinya menggunakan bilangan prima dan menitik beratkan kekuatan kuncinya pada pemecahan masalah logaritma diskrit.

Abstract:
AbstractElGamal cryptosystem has emerged as one of the most important construction in Public Key Cryptography (PKC) since Diffie-Hellman key exchange protocol was proposed. However, public key schemes which are based on number theoretic problems such as discrete logarithm problem (DLP) are at risk because of the evolution of quantum computers. As a result, other non-number theoretic alternatives are a dire need of entire cryptographic community.In 2016, Saba Inam and Rashid Ali proposed a ElGamal-like cryptosystem based on matrices over group rings in ‘Neural Computing & Applications’. Using linear algebra approach, Jia et al. provided a cryptanalysis for the cryptosystem in 2019 and claimed that their attack could recover all the equivalent keys. However, this is not the case and we have improved their cryptanalysis approach and derived all equivalent key pairs that can be used to totally break the ElGamal-like cryptosystem proposed by Saba and Rashid. Using the decomposition of matrices over group rings to larger size matrices over rings, we have made the cryptanalysing algorithm more practical and efficient. We have also proved that the ElGamal cryptosystem proposed by Saba and Rashid does not achieve the security of IND-CPA and IND-CCA.

Abstract:
The latest development in computing methodologies and related steganography based applications had created a novel practice such as telemedicine where patient diagnosis images or allied information can be used diagnosis practices that are located in remote areas. In order to provide accurate and effective telemedicine the flawless or seamless biomedical information is required from patient. With respect to this the medical data may remain prone to get corrupted by hackers or might get manipulated when transmitted through an insecure channel. The cryptosystems which are available are not efficient enough to solve the above mentioned issues. Hence, in this research work a much efficient and effective image steganography technique has been proposed in order to hide the confidential and important image information. We have incorporated Discrete Wavelet Transformation (DWT) technique instead of wavelet transform techniques to embed the secret message in the required cover images. Also, to assure continuous communication through insecure channel, a new model called ElGamal encryption cryptosystem model has been implemented which contains the steganography scheme which has been proposed and developed. To maintain the content of Region of Interest (ROI), Region of Non- Interest (RONI) is used to embed the secret information. The overall performance analysis reveals that the DWT with ElGamal encryption provides more efficient and also have high embedding capacity, imperceptibility when compared to other methods like Hamming code, Syndrome-Trellis Code (STC) and Rivest-Shamir- Adleman (RSA) based methods.

Abstract:
Most of Safes lock system is still using conventional methods nowadays. The conventional method leads to the safes’ burglary. Some of the causes are the safes’ code that can be tracked easily and the key can be duplicated. Previous research on safes’ security has ever been done. The weakness of the study is there is no security system using cryptographic algorithms for data security. The development of a safes security system by implementing ElGamal algorithms is done by following the engineering approach with the stages of methods analysis and design system, implementation and testing of the analysis and the discussion of the overall system. In the analysis and design of mathematical models using ElGamal algorithms, uses fast powering theorems and applications design uses Object OrientedProgramming. In the analysis of hardware refers to the datasheet and calculation of the value of electrical characteristics of the circuit. In the safes lock system, the outcome of the research is a safes prototype which is equipped with enhancements that include a series of processing algorithms, the data viewer, a wireless data transfer device, the Android smartphone as a system of user authorization. For the lock safes systems is using a locked solenoid. The control system is done by a lock safes android smartphone via Bluetooth communication. The test results also indicate the system will open the safes if the code and the public key is entered correctly, and the system will not open if one of the codes or the public-keys are wrong or both are wrong.

In the era of big data, data has now become an asset that held important values, while in the implementation of data delivery, it clearly is not always safe. One of the method to secure data delivery is data encryption using Cryptography. Cryptography provides an encryption service to secure data delivery by transforming it to random values so that it can no longer be read. The goal in this study was to produce an application that could be used to encrypt data, using ElGamal's cryptography method and hash checking using the SHA256 algorithm. After encryption, to ensure the encrypted data is still the original data without any changes or manipulation by unauthorized 3rd party then done by checking the hash generated using SHA256 algorithm. The data used in this study was a sample of raw data from the ATPWTP survey (ability to pay and willing to pay) conducted by the BPS Cirebon (Central Statistics) in 2019 and the data was in the form of Excel and txt files. The encryption process resulted in a cipher larger than the plaintext and takes longer for the data encryption process than during the data cipher decryption process.

Abstract:
At present, due to the various hacking approaches, the protection for any data transmitted through any channel or mode is one of the important issues. Nowadays, providing data security is satisfactory, developments are extended for obtaining data among the transceivers. Security level depends on the size of a symmetric key which is employed for encryption and decryption using various cryptography systems management and in modern approaches like block and RF codes including AES use a larger size of key simultaneously and there exists security problems due to hacking approaches. To illustrate the protection level and hacking problems, a new ECC is presented as well as by employing scalar duplication, the synchronous key is generated and consists of point doubling and point addition. The created focuses are encrypted before transmission by using ECC-Elgamal-Holomorphic (ECCEH) and transferred through a distant channel and encipher data is failed at the receiver using ECCEH which includes the reverse process. The unique standards of cryptography context have been generated by MATLAB; the defined framework has endeavored to the extent that speed, delay as well as control, and many others are accepted in MATLAB 2017a. The user of the sender, the original information is transformed into integer value by employing Holomorphic and encodes it by utilizing the Elgamal ECC algorithm which employs point doubling and point addition. The encoded information is uploaded into the cloud for storage, here www.thingspeak.com is utilized for storage. When the user presents at the receiver request the cloud to access from it, initially the cloud server authenticates the access control strategies of the requester, and then access is provided by the cloud server. If the user authenticates the strategies, then encoded data can download and the original data is decoded by synchronous key employing ECC- Elgamal algorithm. Using original and decrypted data, various performance factors are calculated in terms of execution time, packet delivery ratio, throughput, latency and compare these results with conventional methods and found to be 12%, 31%, 24%, and 8% progress concerned with packet delivery ratio, latency, outturn and execution time.

Abstract:
The proliferation of digitized media due to rapid growth of network multimedia systems has created an urgent need for information security due to the ever increasing unauthorized manipulation and reproduction of original digital data. In this paper an approach based on Merkle-Hellman, ElGamal and Genetic algorithms is proposed for data encryption and decryption. The strength of the cipher is increased further by using genetic algorithm. Experimental results show that the proposed approach can be implemented on images of any size which retain the quality of the image while retrieving the original image. This aspect helps in providing the reduction in block size without compromise in the quality of the image and security as well.

Abstract:
The majority of imaging techniques use symmetric and asymmetric cryptography algorithms to encrypt digital media. Most of the research works contributed in the literature focus primarily on the Advanced Encryption Standard (AES) algorithm for encryption and decryption. This paper propose an analysis for performing image encryption and decryption by hybridization of Elliptic Curve Cryptography (ECC) with Hill Cipher (HC), ECC with Advanced Encryption Standard (AES) and ElGamal with Double Playfair Cipher (DPC). This analysis is based on the following parameters: (i) Encryption and decryption time, (ii) entropy of encrypted image, (iii) loss in intensity of the decrypted image, (iv) Peak Signal to Noise Ratio (PSNR), (v) Number of Pixels Change Rate (NPCR), and (vi) Unified Average Changing Intensity (UACI). The hybrid process involves the speed and ease of implementation from symmetric algorithms, as well as improved security from asymmetric algorithms. ECC and ElGamal cryptosystems provide asymmetric key cryptography, while HC, AES, and DPC are symmetric key algorithms. ECC with AES are perfect for remote or private communications with smaller image sizes based on the amount of time needed for encryption and decryption. The metric measurement with test cases finds that ECC and HC have a good overall solution for image encryption.

It is important to notice that the access control mechanism has been widely applied in various areas, such as on-line video systems, wireless network, and electronic documents. We propose an access control mechanism which is constructed based on two mathematical fundamentals: Lagrange interpolation and ElGamal algorithm. We conduct performance analysis to compare the efficiency of our proposed scheme with that of several related published schemes in both key generation phase and key derivation phase. Our new scheme is proven to be more efficient. It is shown, as expected, a more efficient scheme provides relatively less security and a more secure scheme is relatively less efficient for private keys of the same size.

Though Cloud storage has developed rapidly in recent years, there still exist some problems obviously. Provable Data Possession (PDP) is proposed to solve the problem of data integrity verification at untrusted cloud stores. This study built a new delegation Provable Data Possession (delegation-PDP), which solves problem when the client has no ability to check its remote data. We study the delegation-PDP and use proxy re-encryption to design it. Then we use the improved Elgamal-based algorithm to implement the scheme. Through security analysis and performance analysis, our protocol is provable secure and efficient.

Abstract:
In this paper, we propose a new public key scheme, which is a combination of RSA variant namely the DRSA and the generalization of generalized discrete logarithm problem (generalized GDLP). The security of this scheme depends equally on the integer factorization of [Formula: see text] and the discrete logarithm problem (DLP) on [Formula: see text], where [Formula: see text] is the product of two large primes and [Formula: see text] is the multiplicative group modulo [Formula: see text]. The scheme is a randomized algorithm. It is at least as secure as the DRSA and ElGamal schemes. We also compare the encryption–decryption performance of the proposed scheme with the RSA and DRSA schemes.

Abstract:
A timed commitment is an extension to the standard commitment scheme in which there is a forced-open phase for the verifier to open the committed value even without the help of the committer. The first notion of timed commitment was from Boneh and Naor,2 based on the hardness of the best-known algorithm for computing g(2n) mod N. We use a different approach to design two new schemes. These two schemes are based upon ElGamal encryption and Pubic Verifiable Secret Sharing (PVSS) respectively. Unlike the original scheme, our schemes can be timed precisely, thus easy to be applied in some short-term schemes. We also discuss the implementation of our schemes in contract-signing schemes.

Abstract:
The biggest weakness of Elliptic Curve Cryptography is the difficulty of points counting in elliptic curve which affects the process time. This paper considers a method of simplifying the counting in Elliptic Curve Cryptography and quickening the process time without decreasing the security level. Using ElGamal Algorithm as method of encryption, the implementation also involves Rabin-Miller Prime Number Generator to generate the public key. The system is tested using five different text files with different sizes and lengths. The result shows that by limiting the value of a and b to 1 in the elliptic curve function and also limiting the prime number down to two digits, successfully quicken the process time, the encryption process also takes only a small amount of time.

Full text
Abstract:
In literature, there are a number of cryptographic algorithms (RSA, ElGamal, NTRU, etc.) that require multiple computations of modulo multiplicative inverses. In this paper, we describe the modulo operation and we recollect the main approaches to computing the modulus. Then, given a and n positive integers, we present the sequence (zj)j≥0, where zj=zj−1+aβj−n, a<n and GCD(a,n)=1. Regarding the above sequence, we show that it is bounded and admits a simple explicit, periodic solution. The main result is that the inverse of a modulo n is given by a−1=⌊im⌋+1 with m=n/a. The computational cost of such an index i is O(a), which is less than O(nlnn) of the Euler’s phi function. Furthermore, we suggest an algorithm for the computation of a−1 using plain multiplications instead of modular multiplications. The latter, still, has complexity O(a) versus complexity O(n) (naive algorithm) or complexity O(lnn) (extended Euclidean algorithm). Therefore, the above procedure is more convenient when a<<n (e.g., a<lnn).

Abstract:
In the network security system cryptography plays a vital role for the secure transmission of information. Cryptography is a process of integrating and transferring the data to the genuine users against any attacks. There are two types of Cryptographic algorithm: Symmetric and Asymmetric algorithms. In the symmetric type cryptography, single key is used for both encryption and decryption. Symmetric algorithms are fast and simple. Asymmetric cryptographic algorithm uses different keys such as public key to encrypt the message at sender and private key which is known only to receiver for decrypting the encrypted message. Asymmetric algorithms are more secure and difficult, to decrypt the message unless hacker acquires the knowledge of private key. A new Asymmetric algorithm with Error Detection and Correction mechanism is proposed that can reduce hardware, and improves decryption time and security. Proposed Asymmetric algorithm uses the few properties of: RSA, Diffie-Hellman and ElGamal Algorithms. Performance of asymmetric algorithms is compared with proposed algorithm, which is designed using Verilog HDL. Algorithms are synthesized, simulated, implemented using Vivado and targeted for Artix-7 XC7A100T-1CSG324Carchitecture.Chipscope Pro logic analyzer-Virtual Input Output core is binded to design for hardware debugging, to monitor and capture the output signals at selected specified state by applying random input stimuli at runtime in Nexys4 DDR FPGA Board.

Abstract:
Abstrak— RSA (Rivest Shamir Adleman) merupakan algoritma asimetris yang paling banyak digunakan dalam kriptografi. Dalam beberapa penelitian menyebutkan bahwa proses RSA memakan waktu yang cukup lama. Untuk mempercepat waktu proses dari RSA dilakukan penambahan suatu algoritma CRT (Chinese Remainder Theorem) untuk mengurangi perhitungan aritmatika modular dengan modulus besar dalam RSA yang disebut RSA-CRT. Dalam penelitian ini penulis akan membandingkan dua algoritma asimetris yaitu RSA (Rivest Shamir Adleman) dengan modifkasi RSA yaitu RSA-CRT (Rivest Shamir Adleman-Chinese Remainder Theorem) pada data teks berukuran besar dari segi efisiensi waktu. Algoritma RSA dan RSA-CRT digunakan untuk mengenkripsi dan mendekripsi suatu data teks berukuran 5 mb, 10 mb, 15 mb dan 20 mb untuk dibandingkan efisiensi waktu atau segi kecepatan prosesnya. Hasil pengujian waktu dari penilitian ini menunjukkan bahwa nilai waktu dari proses enkripsi antara algoritma RSA dan RSA-CRT tergolong sama sebab kunci publik yang digunakan rumusnya memang sama. Sedangkan dari proses dekripsi menunjukkan bahwa algoritma RSA-CRT lebih cepat dari pada algoritma RSA biasa. Dari pengujian kecocokan kunci menunjukkan bahwa kunci yang bangkitkan dan digunakan untuk proses enkripsi dekripsi harus berpasangan antara kunci publik dan kunci privatnya. Hasil pengujian ukuran file dari proses enkripsi mengalami kenaikan dengan rata-rata 42.757 kb, sedangkan dari proses dekripsi berkurang dengan rata-rata 0,007 kb dikarenakan terdapat karakter yang tidak dikenali sistem yaitu simbol bullets list yang mengakibatkan file tidak dapat kembali 100% seperti semula. Sehingga dapat disimpulkan bahwa dalam proses dekripsi suatu data teks berukuran besar algoritma RSA- CRT memiliki efisiensi waktu 50% dibandingkan dengan algoritma RSA biasa.Kata Kunci— Algoritma Elgamal, Kriptografi, Enkripsi, Dekripsi, Gambar Warna.

Abstract:
Sharing energy storage (SES) is a novel business model in order to increase the profits and improve the utilization rate of idle energy storage facilities. On the other hand, blockchains can be competently applied in the transaction and operation of SES because of distributed network architecture, traceability and tamper proof. In this paper, a management model of SES based on proxy signatures in the blockchain environment is proposed. Many management models including the principal-agent model are analyzed for SES in terms of benefit, cost, resources, and so on. Moreover, a blockchain framework and a typical transaction process of SES is presented. Finally, a proxy signature mechanism based on the ElGamal algorithm is proposed in order to address the problem that the signature power of nodes cannot be transferred on blockchains. Simulation results show that the proposed proxy signature mechanism can achieve the delegation of digital signature power under the premise of security and reliability, which is suitable for the management model of SES on blockchains.
