A Preliminary Study of Hopping Code Technique Applied in PKE System

摘要

In the view of design and implementation of Passive Keyless Entry (PKE) system based on microcontroller P1C16F639, hoppling code and wireless communication technologies are investigated and discussed in this paper. An improved AES encryption algorithm which achieves a 32-bit encryption is presented. Experiments shows that the algorithm is safety and efficient when it runs on a microcontroller.
