MODIFICATION OF POLLARD RHO ALGORITHM USING NEGATION MAPPING
Barekeng, 2022 El Gamal encryption was introduced in 1985 and is still commonly used today. Its hardness is based on a discrete logarithm problem defined over the finite abelian cyclic group group chosen in the original paper was but later it was proven that using the

Computation of Trusted Short Weierstrass Elliptic Curves for Cryptography
Cybernetics and Information Technologies, 2021 Short Weierstrass elliptic curves with underlying hard Elliptic Curve Discrete Logarithm Problem (ECDLP) are widely used in cryptographic applications. A notion of security called Elliptic Curve Cryptography (ECC) security is also suggested in literature

Can we Beat the Square Root Bound for ECDLP over 𝔽p2 via Representation?
Journal of Mathematical Cryptology, 2020 We give a 4-list algorithm for solving the Elliptic Curve Discrete Logarithm (ECDLP) over some quadratic field 𝔽p2. Using the representation technique, we reduce ECDLP to a multivariate polynomial zero testing problem.

SPRA: Scalable policy‐based regulatory architecture for blockchain transactions
IET Blockchain, Volume 3, Issue 4, Page 265-282, December 2023., 2023 Most of the current regulatory schemes for blockchain transactions are customized for specific blockchain applications and lack generality and scalability. To address these problems, this paper proposes a scalable policy‐based layered blockchain transaction regulation architecture (SPRA), and also designs a regulatory policy description language (XRPL)

A Lightweight Three‐Party Mutual Authentication Protocol for Internet of Health Things Systems
Journal of Healthcare Engineering, Volume 2023, Issue 1, 2023., 2023 In Internet of Health Things (IoHT) systems, there is a two‐hop network structure between the authentication server TA, Internet of Things Connector (IotC), and wearable sensor (WS). Attackers can use the sensor layer network (the first hop) between the IotC and WS to steal patient’s health‐related information and undermine the security of the system ...

A Novel High‐Efficiency Password Authentication and Key Agreement Protocol for Mobile Client‐Server
Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 With the development of wireless technology, people increasingly rely on mobile devices. Since most mobile devices transmit sensitive information via insecure public channels, it is important to design multiauthentication key agreement protocols for security protection.

Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 With the advancement in information and communication technology (ICT), secure farm‐to‐home communication has become an emerging concept. Food is the most basic essential commodity for the survival of human beings which is produced by farmers. However, because of the presence of intermediaries, farmers/producers do not make a sufficient profit and also

Security and Communication Networks, Volume 2023, Issue 1, 2023., 2023 At the moment, digital documents are just as important as paper documents. As a result, authenticity is essential, especially in legal situations and digital forensics. As technology advances, these digital signature algorithms become weaker, necessitating the development of digital authentication schemes capable of withstanding current security ...
