This paper presents an attribute-based framework for secure communications in vehicular ad hoc networks (VANETs) that utilizes attribute-based signatures for message authentication and integrity while preserving vehicle privacy. It enhances existing solutions by integrating traceability and revocation mechanisms to prevent anonymity misuse, thereby improving security and functionality. The framework's performance is evaluated through implementation using a rapid prototyping tool called Charm.

- 1. An Attribute-Based Framework for Secure Communications in Vehicular Ad Hoc Networks ABSTRACT: In this paper, we introduce an attribute-based framework to achieve secure communications in vehicular ad hoc networks (VANETs), which enjoys several advantageous features. The proposed framework employs attribute-based signature (ABS) to achieve message authentication and integrity and protect vehicle privacy, which greatly mitigates the overhead caused by pseudonym/private key change or update in the existing solutions for VANETs based on symmetric key, asymmetric key, and identity-based cryptography and group signature. In addition, we extend a standard ABS scheme with traceability and revocation mechanisms and seamlessly integrate them into the proposed framework to support vehicle traceability and revocation by a trusted authority, and thus, the resulting scheme for vehicular communications does not suffer from the anonymity misuse issue, which has been a challenge for anonymous credential-based vehicular protocols. Finally, we implement the proposed ABS scheme using a rapid prototyping tool called Charm to evaluate its performance. SYSTEM REQUIREMENTS: HARDWARE REQUIREMENTS: System : Pentium Dual Core.
