Security Analysis of Conditional Privacy-Preserving Authentication Schemes for VANETs

IEEE Access, 2023
In order to solve security and privacy-preservation issues in VANETs, a number of conditional privacy-preservation schemes based on certificateless signature (CLS) schemes and certificateless aggregate signature (CLAS) schemes have been proposed. However,

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.

FGDB‐MLPP: A fine‐grained data‐sharing scheme with blockchain based on multi‐level privacy protection

IET Communications, Volume 18, Issue 4, Page 309-321, March 2024.
(1) A blockchain‐based efficient data‐sharing scheme is proposed, which employs the ciphertext policy attribute‐based encryption algorithm to enable fine‐grained sharing of data resources. (2) An anonymous identity authentication method based on ring signatures is proposed, which can effectively protect the user's identity privacy and transaction ...

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.

Functional Message Authentication Codes With Message and Function Privacy

IET Information Security, Volume 2024, Issue 1, 2024.
Functional signatures were allowed anyone to sign any messages in the range of function f, who possesses the secret key skf. However, the existing construction does not satisfy the property of message and function privacy. In this paper, we propose a new notion which is called functional message authentication codes (MACs).
