Abstract:

The code rolling technology has the characteristics of variability, intercept resisting, higher security and higher reliability, and it is widely used in vehicle antitheft alarm system. Based on AES (Advanced Encryption Standard) encryption algorithm and considering the actual application of the system, a code rolling method is proposed and applied in vehicle antitheft system. The tests prove that the method is safe and reliable, and has lower resource consumption and higher efficiency.

Key words: code rolling;AES;vehicle antitheft system
