The new paradigm edge computing demonstrates significant advantages in quality of service including low latency and bandwidth efficiency when deployed in autonomous vehicle applications. However, deploying edge computing in the context of a widely used vehicular ad hoc network (VANET) leads to potential security issues. Blockchain is a promising technology to solve security and trust issues with the identically distributed structure as edge computing and VANET, but its efficiency and scalability limitations constrain the usage in VANET. This paper proposes a hierarchical Directed Acyclic Graph (DAG)based blockchain architecture to overcome these integration challenges. The hierarchical architecture divides the whole system into multiple local chains according to geographical regions to improve scalability while also maintaining a global chain to facilitate security. The DAG-based blockchain structure can better support simultaneous operations to further improve scalability and efficiency. In addition, in recognition of VANET's unique requirements, we design a reputation-based consensus for tip selection algorithm (TSA) to replace the widely used Proof-of-Work TSA in DAG, which ensures security in VANET without heavy computational burden. Our experimental simulations reveal that our proposed scheme not only fortifies security but also elevates scalability and efficiency.

“…Non-degeneracy where Π( , ) is a generator of 2 if is a [25] is an unconditionally hiding and computationally binding scheme that uses secure Elliptic Curve Cryptography (ECC) technology and the intractability of ECDLP, showing perfect privacy-preserving capability. Typically, there are two types of ECPC: the one is nonprivacy-preserving ECPC (NPPPC) [26], the other one is zeroknowledge proof ECPC (zkPC) [27]. The general workflow of the two schemes can be described as the three steps: In zkPC, the verifier will first send a challenge factor to the prover, then the prover will recalculate a new encrypted message 1 with , and send back to the verifier.…”

Internet of Vehicles (IoVs) presents promising opportunities for vehicle to everything (V2X) applications, wherein authentication acts as the cornerstone to realize trustworthy vehicular context and to support advanced applications. However, existing authentication schemes mainly depend on centralized servers with both security and privacy issues. In this paper, we propose a CyberTwin (CT) empowered blockchain framework for authentication, namely CyberChain, to reduce both the communication and storage cost while maintaining vehicular privacy. By designing a blockchain system in the cyberspace, we decouple the consensus process from the physical world, so that the operation cost of blockchain can be reduced. A Privacy-Preserving Parallel Pedersen Commitment (P4C) algorithm is designed to protect the privacy of vehicles and accelerate the authentication process. To further enhance the operation efficiency of CyberChain, we propose a Diffused Practical Byzantine Fault Tolerance (DPBFT) mechanism to reach consensus in the cyberspace that can reduce consensus latency. The proposed cyberchain framework and the associated mechanisms are evaluated by qualitative analysis and simulations. The evaluation results demonstrated that the proposed cyberchain based framework significantly improves the authentication performance in terms of authentication latency, privacy, communication overhead and storage cost.
