Title:
ON THE IMPLEMENTATION OF A LATTICE-BASED DAA FOR VANET SYSTEM
Authors: Doryan Lesaignoux, Mikael Carmona
Abstract:Direct Anonymous Attestation (DAA) is a cryptographic protocol that enables users with a Trusted Platform Module (TPM) to authenticate without revealing their identity. Thus, DAA emerged as a good privacy-enhancing solution. Current standards have security based on factorization and discrete logarithm problem making them vulnerable to quantum computer attacks. Recently, a number of lattice-based DAA has been propose in the literature to start transition to quantum-resistant cryptography. In addition to these, DAA has been adapted to Vehicle Ad-hoc NETwork system (VANETs) to offer secure vehicule-to-vehicule/infrastructure communication (V2V and V2I). In this paper, we provide an implementation of the most advanced post-quantum DAA for VANETs. We explore the cryptographic foundations, construction methodologies, and the performance of this scheme, offering insights into their suitability for various real-world use cases.
