Improving carpooling security using blockchain based decentralized secure ride sharing system

Abstract

Carpooling System (CS) is traveling in a carpool where many people travel in one car. It provides users with a number of vehicles spread across the city. Sensitive information, such as the Ride Sharing (RS) user’s identity, zone, access code, etc., is transmitted through public CS. Due to data breaches, it is necessary to maintain data confidentiality and adequately secure ridesharing users’ data. Criminals use this information to steal information from the CS. Therefore, since attackers can access RS users’ details for illegitimate purposes, developing secure authentication protocols is critical. Traditional car-sharing systems also follow a centralized structure for data sharing. Yet, car-sharing systems also have security challenges. To address this problem, this paper suggests using the Blockchain-based Decentralized Secret Ride Communication System (BDSRCS) for secure data transmission in CS. First, the Proxy Attribute-based Encryption (PAE) approach is utilized to encrypt the RS user’s details in an unreadable format. Subsequently, the BDSRCS approach is used for secure chain link-based communication in the network. This method prevents unauthorized access to data and decentralized data sharing in the network. Thereafter, the Delegated Proof of Stake Key Validation (DPSKV) technique is used to check the primary keys for peer-end verification to hand over the encrypted data. Numerical outcomes establish that the proposed BDSRCS-PAE model enhances the detection rate of suspicious manners and increases the security performance compared with other approaches.
