“…A hybrid scheme using ECC-based crypto combined with blockchain is proposed by Li et al [13] for distributed verifiable message transfer. However, using this scheme, every vehicle in the system must undergo a complex, repetitive registration process each time they change an RSU region.…”

“…Devices rely on the root CA for real-time database updates, rendering them vulnerable to communication bottlenecks. Blockchain-based distributed VANET systems [13,14] maintain vehicle trustworthiness through mutual voting mechanisms and a comprehensive record-keeping system [15] that determines message acceptance or rejection in V2V communication. While effective, these schemes are highly time-consuming and demand substantial computational and storage resources.…”

Vehicular Ad-Hoc Networks (VANETs) offer enhanced road safety, efficient traffic management, and improved vehicle connectivity while dealing with privacy and security challenges in public communication. In these networks, authentication mechanisms are mandatory to establish trust among communicating entities, such as vehicle-to-vehicle (V2V) and vehicle-to-infrastructure (V2I), without losing identity and location-based privacy. The prevailing conventional authentication mechanisms frequently depend on a centralized trust authority (CA) to ensure the mutual verifiability of transmitted messages. Nevertheless, in scenarios where the density of vehicles within the network is notably high, an overwhelming influx of authentication requests may result in a communication bottleneck at the CA, leading to a single point of failure. This paper proposes a novel distributed authentication scheme in a decentralized VANET with multiple independent CAs connected to multiple local inspectors to eliminate a single point of failure. Furthermore, prior solutions lack the capability to immediately revoke a disputed vehicle that is transmitting malicious messages in the network. In this regard, the proposed scheme also facilitates an immediate revocation of a disputed sender to prevent other vehicles from further receiving malicious messages. As vehicles share time-sensitive data for driving assistance, our scheme minimizes the computation and communication costs for V2I key sharing and direct V2V authenticated message sharing significantly compared to previously proposed schemes. Using comparatively lightweight elliptic curve cryptography and eliminating the direct involvement of CAs in the authentication process, we have reduced the overall delays and achieved a maximum of ≈ 3.9 times faster V2I authenticated key sharing, and a maximum of ≈ 7.5 times faster V2V message sharing compared to state-of-the-art bilinear pairing-based protocols. A comprehensive efficiency analysis validates our scheme's ability to outperform time-sensitive responses, such as sending and receiving an alert within nearly 4 milliseconds.INDEX TERMS Vehicular Ad-Hoc Networks (VANETs); Single point of failure; Privacy-preserving authentication; Revocation, Security attacks on VANET; Elliptic Curve Digital Signatures (ECDSA).

A credibilidade e confiança das informações é alvo de constante ameaça. Para o caso de informações relativas à dinâmica de trânsito envolvendo diferentes veículos e condutores, em diferentes vias, isso não é exceção. É o caso para informações geradas relacionadas aos veículos, eventos de trânsito e outros dados nas redes veiculares ad hoc (VANETs - Vehicular Ad-Hoc Networks). Uma das formas de disponibilizar esta confiabilidade é garantindo que a persistência desses dados seja segura o suficiente para impedir alterações. Este trabalho tem como objetivo apresentar uma solução para o armazenamento seguro dessas informações utilizando uma blockchain, pois estas apresentam como uma de suas principais características a capacidade de garantir a imutabilidade dos dados armazenados. Também será apresentado um índice que representa como o motorista se comporta na rede VANET, que utilizará os dados armazenados na blockchain para ser calculado.

“…Another orthogonal work with which our technology can be integrated to provide privacy-preserving auditing is that of Kim et al [34] on a blockchain-based energy trading scheme for a V2V environment by using decentralized identity technology. Li et al [35] proposed a double-layer blockchain and decentralized identifier-assisted secure registration and authentication (BDRA) mechanism for decentralized VANETs. In their implementation, they used Hyperledger Fabric as a blockchain framework; hence, our solution can easily be integrated into decentralized VANETs, since our implementation uses the same blockchain framework.…”

Decentralized Identity Authentication with Auditability and Privacy

Decentralized identity (DID) systems aim to give users full control over their identities by using completely decentralized technologies, such as blockchain or distributed ledgers, as identity providers. However, when user credentials are compromised, it is impossible in existing DID systems for the users to detect credential misuse. In this paper, we propose new DID authentication protocols with two properties: auditability and privacy. The former enables the detection of malicious authentication events, while the latter prevents an adversary from linking an authentication event to the corresponding user and service provider. We present two protocols that achieve auditability with varying privacy and performance guarantees. The first protocol has high performance, but it reveals information about the user. The second protocol achieves full privacy, but it incurs a higher performance overhead. We present a formal security analysis of our privacy-preserving protocols by using the Tamarin prover. We implemented them and evaluated their performance with a permissioned blockchain deployed over the Amazon AWS and a local cloud infrastructure. The results demonstrate that the first protocol is able to support realistic authentication workloads, while the second is nearly practical.
