“…These external attackers may also impersonate legal vehicles to gain access to the system and send unauthorized messages. To safeguard identity privacy, existing techniques such as pseudonym-based approaches [37], [38] or group/blind signature-based techniques [39], [40] can be employed to achieve anonymity with appropriate adjustments. Concerning illegitimate participation, we assume that vehicles undergo authentication prior to joining and interacting with other vehicles, an area of active research in the field of IoVs [37]- [39], [41].…”

The maturing blockchain technology has gradually promoted decentralized data storage from cryptocurrencies to other applications, such as trust management, resulting in new challenges based on specific scenarios. Taking the mobile trust blockchain within a vehicular network as an example, many users require the system to process massive traffic information for accurate trust assessment, preserve data reliably, and respond quickly. While existing vehicular blockchain systems ensure immutability, transparency, and traceability, they are limited in terms of scalability, performance, and security. To address these issues, this paper proposes a novel decentralized vehicle trust management solution and a well-matched blockchain framework that provides both security and performance. The paper primarily addresses two issues: i) To provide accurate trust evaluation, the trust model adopts a decentralized and peer-review-based trust computation method secured by trusted execution environments (TEEs). ii) To ensure reliable trust management, a multi-shard blockchain framework is developed with a novel hierarchical Byzantine consensus protocol, improving efficiency and security while providing high scalability and performance. The proposed scheme combines the decentralized trust model with a multi-shard blockchain, preserving trust information through a hierarchical consensus protocol. Finally, real-world experiments are conducted by developing a testbed deployed on both local and cloud servers for performance measurements.

“…However, these two schemes do not delve into the revocation of vehicles in detail. There are numerous CPPA schemes based on pseudonyms, such as [3,[5][6][7][8][9][13][14][15][16][18][19][20][21][22]. In the fog-based scheme proposed by Zhong et al [3], vehicles generate pseudonyms using two seed values, which partially alleviates the burden on the Trusted Authority (TA) and reduces the storage overhead for vehicles.…”

With the increasing frequency of information dissemination and exchange, the attention paid to security and privacy in the Internet of Vehicles (IoV) is also on the rise. To protect user privacy, many anonymous authentication scheme have been proposed. These schemes assign pseudonyms to vehicles to hide their true identities when communicating with other vehicles or Roadside Units (RSUs). However, existing schemes also face pseudonym issues such as pseudonym abuse, high storage overhead, and low query efficiency. Motivated by this, we propose an RSU-based pseudonym assistance management scheme. In this scheme, RSUs employ dual cuckoo pseudonym filters to manage pseudonyms, effectively improving pseudonym query efficiency, preventing pseudonym abuse, and reducing storage overhead. Additionally, security and performance analyses demonstrate that the proposed protocol offers stronger security features and lower overhead. Besides, our scheme has reduced the generation time of pseudonym to only 0.0039 ms.

“…According to the calculation in Table 3, the pseudonym signature length of this scheme is 324 Bytes. It is slightly higher than the scheme [7], but this scheme adds the distributed tracing function and realizes the tracing of the real identity of the pseudonym without obviously increasing the communication cost. Therefore, this scheme has certain practicality.…”

“…Literature [5][6] used blockchain to design two distributed pseudonyms publishing schemes, but these two schemes do not consider the regulation of pseudonyms. Literature [7] studied the selfgenerated pseudonyms schemes. The pseudonym updating is based on the updated database of the TA.…”

The generation of the pseudonym in vehicular ad hoc networks (VANETs) usually requires the participation of a trusted center (TA), and it needs multiple interactions with the TA. To address these problems, we propose a novel traceable self-generated pseudonym based on the non-interactive zero-knowledge proof (NIZK) and consortium blockchain in VANETs. In our scheme, a self-generated pseudonyms method is introduced to eliminate excessive communication burden, and a consortium blockchain is composed of multiple roadside units (RSUs) to replace the TA. RSUs in the consortium blockchain verify the effectiveness of OBU’s self-generated pseudonyms through the consensus mechanism. Multiple trace authorities (TRAs) are designed to jointly tracking of the real identity of the OBU, which effectively prevents the abuse of supervision by the only supervisor.
