市场上车门无钥匙进入(Passive Keyless Entry，PKE)系统成本高、种类少、应用灵活度低，大部分汽车无法配备。

本文在AES加密算法的基础上，提出了一种类似于滚动加密算法(KEELOQ)的通信安全协议，并应用于无钥匙进入系

统，既降低了成本，又保证了通信安全，且更具灵活性。

关键词：无钥匙进入；AES；加密-Keyless entry door on the market (Passive Keyless Entry, PKE) system is high cost, are few, application flexibility is low, most cars can not be equipped. In this paper, based on the AES encryption algorithm, proposed a similar rolling encryption algorithm (KEELOQ) communications security protocols, and applied to the keyless entry system, not only reduces the cost, but also to ensure communication security, and flexibility .
