| Abstract: | A new type of automobile passive keyless entry system is designed by means of combination of the code hopping technology and the radio-communication technology.The system can recognize user identity without the keystoke,but gurantee security and offer convenience.This paper mainly introduces a code hopping algorithm by means of DES encryption and its software implementation.The algorithrn is secure and reliable and suitable to the implementation on the MCU,and it needs low occupancy of RAM and short runtime. |

| Keywords: | passive keyless entry(PKE) code hopping DES encryption low-frequency initiation |
