However, since CAN BUS is currently used without an encryption process, there may be users who access the system without permission from the outside, and it may be vulnerable to attacks from the outside. In this paper, we implement encryption algorithms that can be used in CAN BUS, such as AES, ARIA, HIGHT and PERSENTS. And compare them by measuring the encryption time, decryption time, and the number of data that can be processed per second. In addition, we propose a 64-Bit AES-Light encryption/decryption algorithm using the AES encryption/decryption algorithm and evaluate its performance." }
