Abstract:
The future of secure and safe transport is the intelligent transport system. Basic safety information that vehicles in the ITS share may lead to the revealing of the vehicles' true identities. Therefore, enemies may abuse these safety warnings. Pseudonyms are aliases that trusted authority give to vehicles to hide their true identities. Different pseudonym creation and dissemination strategies have been proposed to avoid link ability. As these protocol are carried out by Central Authorities, they add overhead to the system. Therefore, the best approach for ITS is to reuse the current pseudonyms by shuffling. A computerized ledger and impenetrable log of transactions, the Blockchain. It does away with the requirement for a centralized authority and offers transaction anonymity, leading in more secure and privacy-protected solutions. To address problems with distribution optimization, blockchain is employed with its distributed consensus to carry out the pseudonym shuffling procedure without the need for a central authority. The outcomes of the shuffle are recorded as transactions in blocks. Randomness using a pseudonym is achieved using blockchain, and it gives the structure robustness. Theother systems would continue to function even if one failed. In the event of certification revocation, the technique additionally offers a completely traceable record. Traditional consensus techniques are used in the current blockchain-based pseudonym shuffling process to enable the cryptographic activity. Overhead interms of execution time and memory utilization results from this. In order to increase the efficiency of consensus in comparison to Proof of Work, Proof of Kernel Work, and Proof of Work, this research provides Proof of Pseudonym consensus protocol for the shuffling method. The execution time of Proof of Pseudonym isshorter than other algorithms. This research focuses on maintaining the Blockchain over roadside Units where we assumed previously that Blockchain can create overhead over the roadside Unit. This Blockchain is tested for Proof of Pseudonym. The security and privacy analysis revealed that our scheme achieves identity privacy, unlinkability, and nonrepudiation properties. Threat analysis evaluates the proposed protocol interms of both internal and external attacks.
