Recently, security vulnerabilities in vehicle keyless entry systems have emerged as a serious problem. Specifically, a replay attack controls a vehicle by retransmitting a command successfully performed by an attacker in the past, easily occurring due to the RF communication characteristics of a smart key. This paper demonstrated that a replay attack could occur in a vehicle keyless entry system. To prevent such a replay attack, we proposed a session key encryption technique based on the Diffie Hellmann protocol. The technique was configured as compatible with existing vehicle keyless entry systems, and minimized the overhead of session key generation and encryption. In the future, the security of vehicle keyless entry systems will become more important due to the popularization of autonomous vehicles. Thus, this study is expected to contribute to strengthening the security of vehicle keyless entry systems. |
