AES encryption algorithm keyless entry system

Passive Keyless Entry (PKE) is accepted and recognized by more and more users for its convenience and security. However, most of the low-end cars can not be equipped with this system because the higher product costs and poorer matching. This article proposes a secure communication protocol of a similar rolling encryption algorithm based on the AES to apply to the keyless entry system, and it can ensure the security and reduces the cost greatly.
