A Secured Certificateless Sign-encrypted Blockchain Communication for Intelligent Transport System

Data communication in the intelligent transport system suffers from many security vulnerabilities. It is essential to protect the vehicles from the distribution of fake messages and concurrently preserve the privacy of those vehicles against tracking attacks. Conventional security methods are not sufficient to provide well-needed security support. In this paper, an efficient technique called Gentle Boost Clustered Diffie-Hellman Certificateless Signcryption-based Blockchain Security Frame-work (GeBlock) is proposed to improve communication security. Initially, the vehicle's information is collected from the dataset. Then, the collected vehicle data are grouped and given to the data block in the underlying Blockchain. The Gaussian expected maximization clustering is a weak learner for grouping each vehicle's data. This process minimizes the processing time for secure data-sharing in the intelligent transport system. After that, the Diffie-Hellman Certificateless Signcryption is performed to protect the data from unauthorized entities. Diffie-Hellman Certificateless Signcryption performs the encryption and digital signature verification process where only an authorized entity can access the vehicle data. In the encryption process, the clustered vehicle data is converted into ciphertext. The digital signature verification is performed on the receiver side to decrypt the ciphertext into the plain text. The confidentiality rate is improved in data communication based on signature verification. Experimental evaluation is performed using Warrigal Dataset, and the different parameters such as clustering accuracy, data confidentiality rate, and processing time are measured.
