| Abstract: | KEELOQ code hopping technology is a nonlinear anti-encryption algorithm designed for secure Remote Keyless Entry（ RKE） systems. It combines a 66-bits transmission length so as to prevent the system from code predicting,code grabbing and code scanning. Because of its feature of high-security,it effectively overcomes the disadvantages of the traditional fixed code technology. This paper researches on the hopping code encryption algorithm and presents the decode method based on KEELOQ encoding technology,which is realized by programming in the microcontroller PIC16F689. The experimental results show that the design achieves the anticipative effects. |
