动态密钥机制AES算法在汽车门禁系统中的应用

Application of dynamic key mechanism of AES algorithm in passive keyless entry system

针对传统汽车无钥门禁系统中AES加密算法固定初始密钥存在密钥管理难度问题,文章提出一种基于动态密钥机制下的AES算法。实验结果表明该算法不仅可以实时有效地更新管理AES算法的初始密钥,而且对系统中身份认证过程中的数据安全防盗性有较好的改善,在一定程度上消除了该系统密钥泄露的安全隐患,对无钥门禁系统中身份认证协议的设计具有一定的参考价值。

In order to solve the key management problem of advanced encryption standard（AES） algorithm in the traditional passive keyless entry（PKE） system, an AES algorithm based on dynamic key mechanism is proposed. The experimental results show that the algorithm can not only update and manage the initial key of AES algorithm in a real-time and effective way, but also improve the data security identity in the system certification process. The hidden danger of the key disclosure in the PKE system is eliminated to a certain extent. The proposed method provides a reference for the design of identity authentication protocol in the PKE system.
