Quantum Cyber-Attack on Blockchain-based VANET. (arXiv:2304.04411v1 [cs.CR])

Blockchain-based Vehicular Ad-hoc Network (VANET) is widely considered as
secure communication architecture for a connected transportation system. With
the advent of quantum computing, there are concerns regarding the vulnerability
of this architecture against cyber-attacks. In this study, a potential threat
is investigated in a blockchain-based VANET, and a corresponding quantum
cyber-attack is developed. Specifically, a quantum impersonation attack using
Quantum-Shor algorithm is developed to break the Rivest-Shamir-Adleman (RSA)
encrypted digital signatures of VANET and thus create a threat for the …
