摘要
汽车门禁系统已成为汽车智能与安全领域的重要一部分.车主手持智能钥匙靠近汽车,通过车载基站与钥匙的双频通信,实现车门的开与关,还可实现发动机的一键启动.同时,对信号加密采用了改进的AES算法,加入了循环扩展密钥,加大了密码的破解难度.并对整个系统进行了建模仿真,分析了信号传输的误码率.图6,表1,参5.
Car Access System has become an important part in the area of intelligence and security, the owner hold smart key near the car, through the car＇s dual-band base station and key communication, to achieve the door open and shut, but also to achieve a key to start the engine. Meanwhile, the signal is encrypted using the AES algorithm improved by adding a cyclic extension keys, increasing the difficulty of cracking passwords. Modeling and simulation for the entire system, analysis transmission bit error rate of the signal. 6figs. ,ltab. ,Srefs.
