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

Cryptanalysis of Compact Certificateless Aggregate Signature Schemes for HWMSNs and VANETs

IEEE Access
Certificateless cryptosystems resolve the critical problems in public-key cryptosystems and identity-based cryptosystems. A certificateless aggregate signature scheme aggregates multiple signatures of multiple signers into a single signature that ...

An Efficient Certificateless Signature from Pairings [PDF]

The First International Symposium on Data, Privacy, and E-Commerce (ISDPE 2007), 2007
A certificateless signature retains the efficiency of Shamir's identity-based signature while it does not suffer from the inherent private key escrow problem, which is first introduced by S. Al-Riyami and K. Paterson in Asiacrypt 2003. In this paper, we proposed a new certificateless signature scheme based on bilinear pairings.

Towards secure and resilient unmanned aerial vehicles swarm network based on blockchain

IET Blockchain, Volume 4, Issue S1, Page 483-493, December 2024.
Abstract Blockchain, as an emerging technology, has found diverse applications in solving trust issues in multi‐party cooperation. The field of Unmanned Aerial Vehicle (UAV) swarm networks is no exception, as UAVs are susceptible to attacks from malicious counterparts due to limited computing and storage resources. In this paper, the authors present an

Secure semi‐automated GDPR compliance service with restrictive fine‐grained access control

SECURITY AND PRIVACY, Volume 7, Issue 6, November/December 2024.
Abstract Sharing personal data with service providers is a contentious issue that led to the birth of data regulations such as the EU General Data Protection Regulation (GDPR) and similar laws in the US. Complying with these regulations is a must for service providers.
