A comparative performance study of cryptographic algorithms for connected vehicles

For security applications for connected vehicles, choosing the best cryptographic algorithm is a real challenge. Traditional cryptography does not fit the constraints on the communication (e. g., bandwidth, delay) environment and the protocols defined in the standards do not allow flexibility. In this work, we provide an analysis of the cryptographic algorithms used to secure V2X communications and an overview of lightweight cryptography algorithms in order to select algorithms that might fit the connected vehicles constraints.
