Abstract

Internet of vehicles, featured with widely distributed vehicle nodes and limited computing power, usually have high performance requirements. Because of this feature, efficient and reliable access control has raised a challenge in Internet of vehicles. Ciphertext-policy attribute-based encryption (CP-ABE) could be denoted as an efficient solution for this problem. However, directly applying traditional single-authority CP-ABE schemes may result in single-point performance bottleneck. Besides, the secrets of the whole system may be leaked if any node is attacked. To solve these challenging tasks, we proposed MA-CP-ABE-CRF, a multi-authority CP-ABE scheme with cryptographic reverse firewalls. The system is designed to grant vehicles fine-grained access control by encrypting data under vehicle attributes. Besides, load balancing of authorization in distributed systems is achieved based on the characteristic of multi-authority. Meanwhile, specific nodes are equipped with cryptographic reverse firewalls (CRFs) to prevent information leakage. As the first scheme with the above features for Internet of vehicles, the system achieves adaptive CPA-security and ASA-security. Through rigorous theoretical analysis and experimental comparison, MA-CP-ABE-CRF is proved to be highly efficient and practical.

期刊介绍: The theoretical, experimental and operational aspects of electrical and electronics engineering and information technologies as applied to Intelligent Transportation Systems (ITS). Intelligent Transportation Systems are defined as those systems utilizing synergistic technologies and systems engineering concepts to develop and improve transportation systems of all kinds. The scope of this interdisciplinary activity includes the promotion, consolidation and coordination of ITS technical activities among IEEE entities, and providing a focus for cooperative activities, both internally and externally.
