Abstract
The promising high data rate of a 5G network enables the reality of Vehicular Ad Hoc Networks (VANET). VANETS are ad-hoc networks and they have limited resources. Providing the confidentiality of data by an access control system in a highly dynamic and automated network is a major challenge. Ciphertext Policy Attribute Based Encryption (CP-ABE) enables the encryption of the access control system to provide the confidentiality of data in a broadcast message. However, as CP-ABE is a form of public key encryption, it consumes high resources. That is a feasibility issue in VANET networks. In this paper, we designing a new algorithm that distribute the CP-ABE encryption tasks on the vehicles cluster. In our scheme, we use Kubernetes to build a cluster of vehicles. Applying CP-ABE microservices to ensure the confidentiality of data greatly mitigates the computation cost on vehicle resources. Our scheme allows to distribute CP-ABE tasks between vehicles using (V2V) connection without needing assistant network components such as a Road-Side Unit (RSU). In our algorithm, we distribute the encryption tasks based on the resource information of vehicles that Kubernetes collect to reduce the execution time of CP-ABE operations. We provide a numerical analysis for our algorithm and discuss our results.
