Research Area:  Vehicular Ad Hoc Networks
Vehicular ad hoc network (VANET) plays an extremely important role in intelligent transportation systems. It enables vehicles equipped with smart devices to communicate with vehicles or available road side units or infrastructure. It has been observed that the security of data and privacy of user are two key challenges for vehicular communication to enable sharing of resources among unfamiliar vehicles. The existing classical cryptography-based schemes are not secure in the quantum computing world due to Shors algorithm. To address the challenges in post-quantum era, we have presented a framework based on short integer solution problem in some lattice that attains all effective identification and authenticity of the user to get authorized access, along with revocation to services. The integrity of proposed framework ensures that information is accurate and can be trusted. This paper ensures conditional autonomous driving and efficient vehicular traffic flow in a VANET. As a result, the presented protocol is suitable for practical applications even in the post-quantum environment, which can be utilized for reliable vehicular communication.
