High Security Design of 2.4GHz Remote Controller in Car Anti-Theft

Abstract:

The effectiveness of car anti-theft relies upon the security of signal from its remote control. However, the signal is easily captured and decrypted for common remote controller. In this paper, the dynamic encryption technology is adopted to enhance the security of signal transmission in the theft-against system. Two random numbers were invoked in the encryption technology. The data was double encrypted according to the two algorithms which were obtained by the two random numbers, respectively. So a same data corresponding to an instruction can be encrypted into a different data. The encrypted data were emitted by NRF24L01. The corresponding instruction was not implemented until the encrypted data were double decrypted by the alarm. The encryption technology can avoid the signal decrypted and coped by the special wireless equipment
