Today organizations face a challenge while recruiting candidates, who provide forged mark sheets in order to get a job. To prevent wrong hiring a detailed and thorough approach is needed to verify the authentication of both the candidate and the marks obtained by him/her. There are so many modern cryptographic protocols available which can be used for authenticating individual’s academic achievement certificates. Visual Cryptography is a simple and secure way to allow the secret sharing of images without any cryptographic computations or the use of encryption or decryption keys. The novelty of the visual secret sharing scheme is in its decryption process where human visual system (HVS) is employed for decryption of secret shares. In this paper we have discussed (3, 3) visual cryptography scheme which can be used to generate shares and distributes them among three parties, i.e. the Job Seeker, Certificate Issuance Authority and the Organization conducting Job interview. Secret message can be decrypted only if all the three shares are available. Every certificate carries a unique number which is encrypted using visual cryptography and without handshaking of all the parties it is impossible to decrypt, thus ensuring full proof authentication.

This study presents a comparative analysis of authentication mechanisms and lightweight security solutions within 5G-enabled IoT networks. With the advent of 5G technology, the proliferation of IoT devices necessitates robust yet efficient security protocols to safeguard sensitive data transmissions. We analyzed various authentication methods, including certificate-based, identity-based, and biometric-based authentication, to evaluate their effectiveness in providing secure and scalable solutions. Additionally, lightweight security protocols such as Advanced Encryption Standard (AES), Elliptic Curve Cryptography (ECC), and SHA-3 were assessed for suitability in resource-constrained IoT environments. We also examined post-quantum cryptographic approaches, including lattice-based cryptography and code-based cryptography, to address future quantum threats. The findings reveal that while traditional authentication methods ensure robust security, lightweight security solutions and post-quantum cryptographic approaches are essential for practical deployment in IoT devices with limited computational capabilities. This research highlights the importance of a tailored security approach in 5G IoT networks, balancing the diverse requirements of IoT devices with the critical need for efficient and secure data transmission. Ultimately, the study underscores the significance of selecting appropriate security mechanisms to achieve a harmonious blend of security and efficiency in 5G IoT deployments.

Full textAbstract:
Abstract Quantum cryptography systems are systems for extending the initial start key, which is required at the start of the system, to ensure information-theoretic authentication of messages in the classical communication channel. In subsequent sessions, a quantum key is generated, part of which is used for authentication in subsequent sessions. There is a fundamental question for quantum cryptography—how many sessions of quantum key distribution (QKD) can be held until the cryptographic properties of the quantum keys are reached a critical level, after which they can no longer be used for cryptographic purposes, and a new restart of the quantum cryptography system will be required. An explicit expression of the allowable number of sessions of quantum key distribution is obtained. It is shown that for the real parameters of the system, it is possible for the system to work almost indefinitely until the next initialization.

Cryptographic frameworks depend on key sharing for ensuring security of data. While the keys in cryptographic frameworks must be correctly reproducible and not unequivocally connected to the identity of a user, in biometric frameworks this is different. Joining cryptography techniques with biometrics can solve these issues. We present a biometric authentication method based on the discrete logarithm problem and Bose-Chaudhuri-Hocquenghem (BCH) codes, perform its security analysis, and demonstrate its security characteristics. We evaluate a biometric cryptosystem using our own dataset of electroencephalography (EEG) data collected from 42 subjects. The experimental results show that the described biometric user authentication system is effective, achieving an Equal Error Rate (ERR) of 0.024.

<p class="abstract">A recent development in the adhoc network is a vehicular network called VANET (Vehicular Adhoc Network). Intelligent Transportation System is the Intelligent application of VANET. Due to open nature of VANET attacker can launch various kind of attack. As VANET messages are deal with very crucial information’s which may save the life of passengers by avoiding accidents, save the time of people on a trip, exchange of secret information etc., because of this security is must be in the VANET. To ensure the highest level of security the network should be free from attackers, there by all information pass among nodes in the network must be reliable i.e. should be originated by an authenticated node. Authentication is the first line of security in VANET; it avoids nonregistered vehicle in the network. Previous research come up with some Cryptographic, Trust based, Id based, Group signature based authentication schemes. A speed of authentication and privacy preservation is important parameters in VANET authentication. This paper addresses the computational analysis of authentication schemes based on ECC. We started analysis from comparing plain ECC with our proposed AECC (Adaptive Elliptic Curve Cryptography) and EECC (Enhanced Elliptic Curve Cryptography). The result of analysis shows proposed schemes improve speed and security of authentication. In AECC key size is adaptive i.e. different sizes of keys are generated during key generation phase. Three ranges are specified for key sizes small, large and medium. In EECC we added an extra parameter during transmission of information from the vehicle to RSU for key generation. Schemes of authentications are evaluated by comparative analysis of time required for authentication and key breaking possibilities of keys used in authentication.</p>

With the increasing popularity of information technology in communication network, security has become an inseparable but vital issue for providing for confidentiality, data security, entity authentication and data origin authentication. Steganography is the scheme of hiding data into a cover media to provide confidentiality and secrecy without risking suspicion of an intruder. Visual cryptography is a new technique which provides information security using simple algorithm unlike the complex, computationally intensive algorithms used in other techniques like traditional cryptography. This technique allows visual information to be encrypted in such a way that their decryption can be performed by the Human Visual System (HVS), without any complex cryptographic algorithms. To provide a better secured system that ensures high data capacity and information security, a multilevel security system can be thought for which can be built by incorporating the principles of steganography and visual cryptography.

Full textAbstract:
Biometric systems refer to biometric technologies which can be used to achieve authentication. Unlike cryptography-based technologies, the ratio for certification in biometric systems needs not to achieve 100% accuracy. However, biometric data can only be directly compared through proximal access to the scanning device and cannot be combined with cryptographic techniques. Moreover, repeated use, improper storage, or transmission leaks may compromise security. Prior studies have attempted to combine cryptography and biometrics, but these methods require the synchronization of internal systems and are vulnerable to power analysis attacks, fault-based cryptanalysis, and replay attacks. This paper presents a new secure cryptographic authentication method using biometric features. The proposed system combines the advantages of biometric identification and cryptographic techniques. By adding a subsystem to existing biometric recognition systems, we can simultaneously achieve the security of cryptographic technology and the error tolerance of biometric recognition. This method can be used for biometric data encryption, signatures, and other types of cryptographic computation. The method offers a high degree of security with protection against power analysis attacks, fault-based cryptanalysis, and replay attacks.

<em>There is an increasing need for privacy and information security in present-day scenarios since sensitive information is being stored over internet. Cryptography is considered as an effective solution for ensuring security of data. To address certain limitations, cryptography and biometric combined. The system is known as Cryptobiometric system. Cryptobiometric system which uses biometric traits to protect or generate cryptographic hash. But hash generation based on biometric has some problems with privacy of biometric and revocability of biometric. Thus, there is a need to create a productive crypto-biometric framework which fulfills protection and revocability of biometric information. Validation is the demonstration of demonstrating character of a PC framework client. Interestingly, with distinguishing proof, the demonstration of showing someone or something personality, verification is the most common way of checking that character.The Authentication techniques are classified into three, i) Knowledge based ii)Property based iii) Biometric based. This project is to generate a cryptographic hash from cancellable fingerprint template. Authors propose Cartesian transformation to induce cancellable template from fingerprint template of users. The generated hash value is used for authentication purpose.</em>

Full textAbstract:
The key derivation function is a specific cryptographic algorithm that transforms private string and public strings into one or more cryptographic keys. The cryptographic keys are essential for protecting electronic data during transmission on the internet. This function is designed based on a computational extractor and pseudorandom expander and is typically constructed using various cryptography ciphers such as stream ciphers, keyed-hash message authentication codes, and block ciphers. Having secure and efficient key derivation function designs is essential in the development of numerous security systems. A vulnerable key derivation function could potentially give attackers the ability to compromise an otherwise secure cryptosystem. This research proposes a different approach by combining two different cryptography ciphers to develop key derivation functions. The findings demonstrate that a computational extractor utilizing keyed-hash message authentication codes and a pseudorandom expander using stream ciphers maintain the highest level of security while also providing efficiency benefits in terms of execution time compared to existing key derivation function schemes.

Security is crucial for wireless communication networks, especially as quantum computing advances rapidly. It won’t be long before quantum attacks become feasible, potentially crippling large wireless networks within minutes. Current methods for securing connections and transactions—such as keys, certificates, and data—could be compromised by quantum computers. One concern is the use of fake base stations with stronger signal strengths to lure users into connecting with them in wireless communication network. A quantum-powered attacker could easily break traditional encryption algorithms and launch various attacks almost instantly. An example of this is the "bidding down" attack, where an attacker convinces both the user and network entities that security features are not upheld, despite their actual presence. This type of attack exploits the security weaknesses of older mobile networks. This paper explores security advancements and challenges related to contemporary public key cryptography, including RSA algorithms based on factorization and discrete logarithm problems with Diffie-Hellman and Elliptic-Curve Cryptography (ECC). While these methods provide adequate protection today, quantum computers could potentially break these algorithms or weaken cryptographic keys and hashes within minutes. Quantum cryptography, or quantum-resistant cryptography, objectives to develop algorithms and protocols resilient to quantum computing threats. This paper examines security vulnerabilities in wireless communication networks, focusing on key confirmation and authentication mechanisms. We propose a robust authentication and key agreement protocol for 5G networks using quantum-resistant cryptography. Our proposed protocol, verified with a verification tool, enhances the security of the authentication and key agreement procedures in wireless communication networks.

Full textAbstract:
The rapid advancement of quantum computing technology poses a significant threat to conventional public key cryptographic infrastructure. The SM2 (state key cryptography algorithm no. 2) elliptic curve public key cryptographic algorithm, which adopts elliptic curve cryptography, has demonstrated strong resistance to quantum attacks. However, existing signcryption schemes remain vulnerable due to their reliance on a single certification authority (CA) managing all keys. The cryptography fundamental logics (CFL) authentication process eliminates the need for third-party involvement, achieving decentralized authentication and reducing the burden on certificate generation centers. Therefore, a decentralized signcryption scheme based on CFL was proposed using the SM2 national cryptographic algorithm. Unlike traditional signcryption schemes, this approach does not depend on the certification authority’s private key during the public–private key generation process. This innovation helps avoid risks associated with certification authority private key leakage and ensures decentralized characteristics. The proposed scheme was rigorously verified under the random oracle model (ROM) and based on the complexity assumption of the elliptic curve Diffie–Hellman (ECDH) problem. The theoretical analysis and experimental results demonstrate that compared to traditional methods, the proposed scheme exhibits higher efficiency in communication and computation. Specifically, the proposed scheme reduces computational overheads by approximately 30% and communication overheads by approximately 20% in practical working environments. These quantitative improvements highlight the scheme’s promising application prospects and practical value.

The article is devoted to the analysis of modern trends in the development of cryptography, which are related to the issues of cryptography of the past and are reflected in the prospects for the development of cryptography in the future. New trends in the development of cryptography that are relevant in recent decades are highlighted, the main ones of which include: awareness of the mathematical nature of data encryption problems, the rapid increase in the volume of processed and encrypted information that is distributed among a large unlimited circle of users of the modern data transmission devices, practical and theoretical interest of user s in cryptography. It analyzes the continuity of the issues facing cryptography. Among such issues there are: an importance of the human factor in the use of any cryptographic system, the traditional participation of the state in the cryptography development, as well as the theoretical substantiation of ideas of the cryptographic data protection, generalizing the practical experience of using encryption. The author also analyzes the main tasks of cryptography, which include identification, authentication, maintaining the integrity, confidentiality and availability of information during its transfer and storage, emphasizing the need to solve them within the framework of the design and implementation of the complex security systems. Using the development of quantum cryptography as an example, the article emphasizes that the development of new approaches to the cryptographic data protection traditionally leads to the emergence of new vulnerability factors, which means that the traditional issue of cryptography is also to stay ahead of potential attackers.

Data transmission in intelligent transportation systems is being challenged by a variety of factors, such as open wireless communication channels, that pose problems related to security, anonymity, and privacy. To achieve secure data transmission, several authentication schemes are proposed by various researchers. The most predominant schemes are based on identity-based and public-key cryptography techniques. Due to limitations such as key escrow in identity-based cryptography and certificate management in public-key cryptography, certificate-less authentication schemes arrived to counter these challenges. This paper presents a comprehensive survey on the classification of various types of certificate-less authentication schemes and their features. The schemes are classified based on their type of authentication, the techniques used, the attacks they address, and their security requirements. This survey highlights the performance comparison of various authentication schemes and presents the gaps in them, thereby providing insights for the realization of intelligent transportation systems.

Verifying an individual's identity before granting them access to a linked device, an internet service, or another resource is known as user authentication. The significance of authentication lies in its ability to safeguard data, apps, and networks for companies by limiting access to their protected resources to only authorized individuals or processes. This paper used the popular Big data technology Apache Spark for storing, and processing large data and proposed a novel authentication framework. A viable replacement for conventional alphanumeric passwords, bio-metric and facial authentications with dynamic symbol selection as an authentication. This authentication is tested in the Apache spark cluster which is the most distributed system. In these methods, SHA512 cryptography is used in several ways and comparison is done using existing authentication and machine learning algorithms.

Full textAbstract:
Vehicular Ad-hoc Networks (VANETs) have high requirements for real-time data processing and security of message authentication. In order to solve the computing power asymmetry between vehicles and road side units (RSUs) in VANETs under high-density traffic, accelerate the processing speed of message authentication, and solve the problems of high computational overhead and long message authentication time caused by the use of bilinear pairing encryption technology in similar message-batch-authentication schemes, we propose introducing the concept of edge computing (EC) into VANETs and using idle nodes’ resources to assist the RSU in quickly authenticating messages to achieve computing power load balancing under multiple traffic flows. We propose introducing the idea of edge computing (EC) into VANETs and using idle nodes’ resources to assist RSUs in quickly authenticating messages. This scheme performs two identity-based message authentications based on the identity signature constructed by elliptic curve cryptography (ECC). One of them is the batch authentication of the vehicle sending messages by the RSU-authenticated vehicles with free resources, as temporary edge computing nodes (TENs), and the other is the authentication of the temporary TEN messages by the fixed-edge-node RSUs. The resources of the TEN are used to reduce the computational burden of RSUs and message authentication time, thereby improving the efficiency of system authentication of messages. We performed a security analysis of the scheme to prove its security properties and compared it with other schemes in terms of performance. The experimental results show that our scheme has a transmission overhead of 2400 bytes when there are four TENs, and the number of verification message requests reaches 20, which outperforms other methods. The gap will be more evident as the numbers of TEN and message verification requests increase.

The Internet of Things (IoT) technology has changed the contemporary digital world. Devices connected to the IoT have sensors embedded within them. All these devices are purposely connected to share data among them through the Internet. Data sharing among IoT devices needs some security protocols to maintain the privacy and confidentiality of information. IoT devices have less computing power to perform various operations of a cryptographic process. So, there is a need of cryptographic approach to reduce the computational complexity for resource-constrained devices and provide data security. However, storing data over the cloud server also reduces storage overhead, but data transmission via the cloud is not always secure. Data integrity and authentication can be compromised because the end user can only access the data with the help of a cloud server. To ensure the security and integrity of the data, various cryptographic techniques are used. Therefore, in this paper, we propose a secure and optimized hybrid cryptographic scheme for the secure sharing of data by combining Advanced Encryption Standard (AES) and Elliptic Curve Cryptography (ECC). To ensure authentication and data integrity, the proposed scheme primarily uses the Message Authentication Code (MAC). The encrypted messages are stored on a cloud server to reduce storage overhead. The experimental findings demonstrate that the proposed scheme is effective and produces superior results as compared to existing approaches.

In order to effectively solve the increasingly prominent network security problems, cryptographic algorithm is the key factor affecting the effectiveness of IPSec VPN encryption. Therefore, this paper mainly studies cryptographic algorithms and puts forward the following solutions: briefly analyze the concept and function of IPSec VPN, as well as the basic theoretical knowledge of IPSec Security Protocol and cryptography, and analyze the traditional cryptography, modern cryptography, symmetric cryptographic algorithms and asymmetric algorithms, and their security. At the same time, the executable and security performances of AES and DES algorithms are compared and analyzed. This paper studies the elliptic curve encryption algorithm ECC, expounds the mathematical basis of realizing the algorithm, and compares and analyzes the security performance and execution efficiency of ECC. Based on the above two algorithms, a hybrid encryption algorithm is proposed, and the realization mechanism of the hybrid encryption algorithm is studied and discussed. The hybrid encryption algorithm combines the advantages of ECC and AES. The algorithm selects 128-bit AES and 256-bit ECC. In order to better cover up plaintext C, AES is used to encrypt information. While enhancing security, speed is also considered. The improved encryption, decryption, and signature authentication algorithms are relatively safe and fast schemes. ECC algorithm is improved, and on this basis, ECC algorithm and AES algorithm are combined. Moreover, HMAC message authentication algorithm is added, and the performance of the improved algorithm is significantly improved.
