Abstract:

This paper provides an enhanced technique for improving the security and protecting the privacy of the cloud computing users by encrypting the data before it reached to server’s storage. Encrypting means the process of converting information or data into unreadable language to prevent unauthorized access. This paper will propose a mobile application design, which will allow the user to encrypt and decrypt the data hence maintaining security and privacy. In the proposed system design, the AES Algorithm will handle the encryption of the data using a keyword which will be defined by the user duri

Abstract:

This research paper study the application of chaos baker map for digital image encryption in different operation modes. The employed modes include the electronic code book (ECB), cipher block chaining (CBC), output feedback chaining (OFB), and cipher feedback chaining (CFB). The proposed method works by applying the chaos baker map in different operation modes for encrypting digital images. A group of tests were carried out to examine the impact of operation modes on chaos baker-based encryption. This is done using several encryption metrics like visual inspection, statistical measures, entrop

Abstract:

Messaging applications are now adopting the concept of end to end encryption. Signal uses the Signal Protocol which has no known vulnerabilities for its end to end encryption. The protocol was explained in this work and possibilities of improvements were explored. It was discovered that the protocol implementation uses the SHA-512 hash, AES in CBC mode for encryption and HMAC for authentication. These Cryptographic Primitives were replaced with more efficient alternatives, Blake2, Chacha20 and Poly1305 respectively. An application was created to test the running time of the proposed cryptograp

Abstract:

Personal and network encryption application models nowadays are analyzed in this paper, then a team secrecy encryption application model is proposed based on practical applications. In this model, members of one team have same access authority for electronic documents, and team is the smallest unit of key distribution. Procedures of distribution, transmission and updating key are offline. This model is suitable for co-confidential application among many departments which are loose coupling. An encryption system is implemented based on this model aimed at protecting Microsoft office document.

Abstract:

Medical images are regarded as important and sensitive data in the medical informatics systems. For transferring medical images over an insecure network, developing a secure encryption algorithm is necessary. Among the three main properties of security services (i.e., confidentiality, integrity, and availability), the confidentiality is the most essential feature for exchanging medical images among physicians. The Goldreich Goldwasser Halevi (GGH) algorithm can be a good choice for encrypting medical images as both the algorithm and sensitive data are represented by numeric matrices. Additiona

Abstract:

The development of information technology, has made the information as a basic requirement for everyone. To secure the information we have, one of the techniques of data and information security is cryptography. Therefore, the authors make an application that can maintain the confidentiality of the information and the intended application is web-based cryptographic applications. This application can be used to secure the data. In this application, the cryptographic algorithm to be used is the algorithm Rivest Code 4 (RC4). RC4 is a stream cipher algorithm that processes the type of data input

Abstract:

In this paper, a digital image encryption scheme is investigated based on n dimensional (n-D) generalized hyper-chaotic cat map. Firstly, the transformation matrix in n-D map is constructed by using n(n-1)/2 transformation sub-matrix multiplication. Secondly, a novel approach is proposed that the possible sorting numbers of transformation sub-matrix multiplication are used as encrypted keys, which is applied to image encryption. It is the first time in the literature to report the image encryption scheme based on high dimensional hyper-chaotic cat map. Both theoretical analysis and numerical e

Abstract:

A large number of sensors and intelligent devices are interconnected via the internet to collect data as part of the internet of things (IoT) applications. Data security is one of the important challenges for these applications due to vulnerability of the internet. IoT devices limiting factors, such as delay-sensitivity, restricted memory, and low computing capability, make choosing the appropriate data encryption standard extremely important. The current research focuses on evaluating four data security, block cipher standards for the IoT smart home application. Considering the encryption/dec

Abstract:

Designing chaotic systems with specific features is a hot topic in nonlinear dynamics. In this study, a novel chaotic system is presented with a unique feature of crossing inside and outside of a cylinder repeatedly. This new system is thoroughly analyzed by the help of the bifurcation diagram, Lyapunov exponents’ spectrum, and entropy measurement. Bifurcation analysis of the proposed system with two initiation methods reveals its multistability. As an engineering application, the system’s efficiency is tested in image encryption. The complexity of the chaotic attractor of the proposed system

Abstract:

Cryptography is the science of maintaining data confidentiality, where the original text (plaintext) is encrypted using an encryption key to be ciphertext (text that has been encrypted). In this case cryptography secures data from a third party so that the third party cannot know the original contents of the data because the one who holds the key for encryption and decryption is only the sender and receiver. There are several cryptographic methods that are commonly used, one of which is DES or Data Encryption Standard. DES is included in the key-symmetric cryptography and is classified as a bl

Abstract:

Abstract Functional encryption (FE) can provide a fine-grained access control on the encrypted message. Therefore, it has been applied widely in security business. The previous works about functional encryptions most focused on the deterministic functions. The randomized algorithm has wide application, such as securely encryption algorithms against chosen ciphertext attack, privacy-aware auditing. Based on this, FE for randomized functions was proposed. The existing constructions are provided in a weaker selective security model, where the adversary is forced to output the challenge message be

Abstract:

Due to the increasing variety of encryption protocols and services in the network, the characteristics of the application are very different under different protocols. However, there are very few existing studies on encrypted application classification considering the type of encryption protocols. In order to achieve the refined classification of encrypted applications, this paper proposes an Encrypted Two-Label Classification using CNN (ETCC) method, which can identify both the protocols and the applications. ETCC is a two-stage two-label classification method. The first stage classifies the

Abstract:

VoIP application usage has increased from time to time and makes our daily life more convenient. VoIP application has features to make a phone call, send a text message and share the file through the apps for free. However, most of the users did not seem aware of VoIP security features such as authentication ability, password encryption ability, or voice or audio and text communication encryption ability. It is essential to ensure the VoIP used is secure from password decrypter and eavesdrops the user conversation. Thus, the first objective of this research was to study and investigate VoIP ap

Abstract:

Information security in Electronic commerce is a very important, and image is one of the important information. Classic image encryption algorithms include Arnold cat transformation, magic square transformation, Hilbert transformation, and the Arnold cat transformation is widely applied and has the best scrambling effect effectively. It puts forward an algorithm of image encryption based on Arnold cat and chaotic map. The experiment results show that the key quantities and scrambling effect are improved obviously, and it is rapid and security.
