A Secure Way of Communication for Smart Grid Networks
International Journal of Distributed Sensor Networks, Volume 2025, Issue 1, 2025.In 2021, Khan et al. suggested a scheme based on smart grid networks. They deployed the random oracle model to justify the security of their scheme formally. They also verified the security of the scheme using the AVISPA software tool. We studied this scheme and found some security issues. The scheme suffers from a confidentiality breach attack.

A Blockchain‐Based Certificateless Anonymous Cross‐Domain Authentication Scheme for IoV
International Journal of Intelligent Systems, Volume 2025, Issue 1, 2025.As an essential component of the internet of things, the internet of vehicles (IoV) holds broad application prospects in areas such as safe driving, intelligent transportation, and service reservations. Due to the security and privacy requirements, anonymous authentication schemes are widely used in IoV. However, traditional certificate‐based anonymous

Multi‐hop anonymous payment channel network based on onion routing
IET Blockchain, Volume 4, Issue 2, Page 197-208, June 2024.To solve the payment channel network path privacy problem, we analyse the multi‐hop anonymous and privacy‐preserving payment channel network scheme and propose a multi‐hop anonymous payment channel network based on onion routing based on it. The scheme removes the routing assumptions of the original scheme, designs an onion routing‐based payment ...

Can we Beat the Square Root Bound for ECDLP over $\mathbb{F}_{p^2}$ via Representations?
, 2019 We give a 4-list algorithm for solving the Elliptic Curve Discrete Logarithm (ECDLP) over some quadratic field $\mathbb{F}_{p^2}$. Using the representation technique, we reduce ECDLP to a multivariate polynomial zero testing problem. Our solution of this
