Abstract: Data storage is one of the major applications of vehicular cloud computing (VCC) where the data is shared concurrently among many vehicles participating in vehicular communications. Integrity and non-repudiation are some of the important security challenges encountered during the provisioning of data storage services. This paper proposes an integrity and non-repudiation verification scheme in a dynamic vehicular cloud storage environment. Vehicle authentication is performed by employing Boneh-Lynn-Shacham (BLS) short signature mechanism. The cryptographic hash function and bitwise exclusive-OR (XOR) operation provide data integrity checking of messages which are uploaded from the vehicle to the cloud. RSU acts as a trusted verifier for data transactions. We evaluated the efficiency of the proposed scheme against standard attacks such as replay attack and tampering attack. Extensive simulations are carried out and the results are compared to ID-based cryptographic schemes. The scheme proposed achieved better in terms of computation overhead, average throughput and communication overhead.
