Electronic lock keyless entry system with random key

Abstract

The invention discloses a random key electronic lock keyless entry system, which is composed of an electronic key and an electronic lock. The key data of the electronic lock is changed by the user setting, the electronic lock is paired with the electronic key without restriction, and the electronic key is paired with the key data of at least one electronic lock. The verification code of the system is encrypted by the random key and private key code in the conditional interception of nonlinear changes. The verification code is irregular each time, and the private key code is not exposed during the verification process, which effectively prevents chip decryption from being cracked in batches and signals Interception, analysis and cracking are realized to be safe, intelligent, flexible, easy to carry and easy to use.

Description

technical field [0001] The invention relates to the technical field of electronic locks, in particular to a keyless entry system. Background technique [0002] Keyless entry systems on the market mainly use RFID radio frequency technology and rolling code control technology. According to the rolling code control principle, the key is the core security of the rolling code system. With the development of chip decryption technology, the early rolling code chip was successfully cracked, and the probability that the chip can be cracked in the near future is increasing. Keys, algorithms, the same batch of rolling code system chip products will have major security risks. There are endless cracking methods. For the cracking of wireless control systems, the two popular cracking methods are chip decryption batch cracking and signal interception analysis cracking. [0003] The electronic key of the keyless entry system on the market has a single function and unstable security. One el...
