摘　　要：针对传统汽车无钥匙进入与启动系统的安全性能和识别能力不足,提出一种基于Turbo码前向纠错三次重传的无钥匙进入与启动系统的加密算法。构建无钥匙进入与启动系统的Turbo码模型,设计无钥匙进入与启动系统的加密传输协议,采用Turbo码前向纠错三次重传方法数据加密方案的编码结构优化设计,得到加密和解密的输入输出模型。仿真结果表明,采用该加密算法提高了无钥匙进入与启动系统的安全性和识别能力。Passive entry and passive start（PEPS）system of the traditional car is unsafe and unrecognizable,based on forward error correction Turbo code three times of retransmission,PEPS system encryption algorithm is proposed.PEPS system of Turbo code model is built,PEPS system encryption transmission protocol is designed,Turbo code forward error correction three retransmission coding structure is optimized,data encryption and decryption scheme of the input and output model is obtained.The simulation results show that this encryption algorithm can improve safety and recognition of PEPS system.
