Post Quantum Secure Aggregate Signature Assisted Data Authentication for Internet of Vehicles

The Internet of Vehicle enables million of vehicles to transfer sensitive information through an Internet of Things assisted networking system. It is a very challenging idea wherein different types of data authentication protocols have been designed number theory based assumptions (RSA/DLP). The quantum computers are big threats to number theoretic assumptions. In this article, we have designed a post quantum secure aggregate signature assisted data authentication framework for internet of vehicles. Further, a secure aggregate signature assisted data authentication framework have been proposed that supports batch data verification. We have proposed an efficient aggregate signature to verify authenticity of multiple vehicles in one step. The security of protocol relies upon two assumptions, (1) Module Learning With Errors and (2) Module Short Integer Solution. The proposed design ensures security against quantum attacks. The design is simulated in ns3 to capture latency and throughput, respectively.
