【Abstract】We propose an efficient revocable message authentication scheme to address the security and privacy problems of vehicular networks. The core of our scheme is a pairing-free online/offline certificateless signature with efficient revocation. To further enhance efficiency, our scheme allows roadside unit to assist nearby vehicles to verify signatures through the use of cuckoo filter. To handle revocation, the key generation center will periodically update time keys of the non-revoked users. To reduce the workload of the key generation center, we apply a node selection algorithm known as KUNodes. We also propose to utilize blockchain technology to store the revocation list. Hence, the transparency of user revocation is enhanced, as the vehicles can check the state of revocation list from the immutable blockchain. (C) 2020 Elsevier Ltd. All rights reserved.
