Embodiment Construction

[0017] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0018] A random-key electronic lock keyless entry system is composed of an electronic key and an electronic lock. Including signal transceiver module, MCU microprocessor, keyboard unit respectively. The signal transceiver module can be one or more combinations of infrared signal transceiver module, wireless radio frequency signal transceiver module, Bluetooth signal transceiver module, WIFI signal transceiver module, etc.

[0019] Such as figure 1 As shown in 101, the electronic lock is in the standby state, and the MCU microprocessor changes the data non-linearly within a preset time to generate a random key R.

[0020] 102 Set the key data of the electronic lock: identity code F, private key code A, the setting method can be set by directly inputting the password through the keyboard unit of the electronic lock or by intercepting the data through the preset condi...

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...
