Design of RKE System Based on KEELOQ Encryption Technology

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 researched on KEELOQ encryption algorithm and presented a designed RKE system based on KEELOQ technology. When the software and hardware were designed, the whole RKE system was afterwards made as a prototype for the functionality tests. The experimental results showed that the design achieved the anticipative effects.
