Blockchain-Based Efficient Decentralized Key Management for VANET using RSA

One of the significant challenges in more extensive data is a threat to the digital technology process and insecure communication. The drawback is that the data transmission of the process is the communication process's uncertainty and the data processing's misclassification. The resolved issues to introduce the Rivest Shamir Adleman (RSA) blockchain technology for key generation are more efficient and ensure a secure communication process. Additionally, the proof-of-work (POW) consensus algorithm creates a new block to validate the transaction process. Furthermore, the Advanced Encryption Standard (AES) algorithm uses the key for encryption and decryption performance in an accurate and secure transaction. Finally, the proposed method determines the routing in the key generation of the area as an encrypted process. Its key is received from the sender of the process, and the blockchain technique provides is higher prediction level and more efficiency in the performance. The process is more reliable and has a high level of performance, and the presented method maintains the standard scalability of the process. The proposed techniques reduce time complexity and low power consumption, and the performance is within an accurate range of 92% of the performance.
