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 ...

A Novel Security Scheme Supported by Certificateless Digital Signature and Blockchain in Named Data Networking

IET Information Security, Volume 2024, Issue 1, 2024.
Named Data Networking (NDN) is a promising network architecture that differs from the traditional TCP/IP network, as it focuses on data rather than the host. A new secure model is required to provide the data‐oriented trust instead of the host‐oriented trust.

The efficiency of solving multiple discrete logarithm problems and the implications for the security of fixed elliptic curves

, 2004
This paper examines the cryptographic security of fixed versus random elliptic curves over GF(p). It assumes a precomputation for use in breaking the elliptic curve discrete logarithm problem (ecdlp) can be made for fixed curves.

Elliptic curves with a pre-determined embedding degree [PDF]

, 2009
A pairing over an elliptic curve E(F_) to an extension field of F_ has begun to be attractive in cryptosystems, where k is called the embedding degree. The cryptosystems using a pairing are called the pairing-based cryptosystems.
