Problems solved by technology
However, once the key exchange protocol fails and the security of the Bluetooth component of the lock fully relies on the built-in security policy of Bluetooth low energy technology, the Bluetooth wireless communication link may still be subject to passive eavesdropping or man-in-the-middle attacks
Therefore, in the application of Bluetooth smart lock, it is not safe to transmit plaintext or reversible ciphertext on the Bluetooth wireless communication link

The bluetooth intelligent lock key composite verification system comprises an intelligent handheld device terminal and a bluetooth intelligent lock controller terminal; information interaction between the intelligent handheld device terminal and the bluetooth intelligent lock controller terminal is realized via bluetooth link; the intelligent handheld device terminal comprises a first lock core ID memory, a first salt information mixer, a first clock, a first lock core opening time memory, a first summary generator, a first local unlocking key memory, and a first bluetooth communication module; the bluetooth intelligent lock controller terminal comprises a second lock core ID memory, a second salt information mixer, a second clock, a second lock core opening time memory, a second summary generator, a second local unlocking key memory, a second unlocking key comparison device, and a second bluetooth communication module. The bluetooth intelligent lock key composite verification system is capable of increasing the safety of bluetooth intelligent locks greatly.
Description
technical field [0001] The invention belongs to the field of intelligent locks, and more specifically relates to a bluetooth intelligent lock control. Background technique [0002] Bluetooth (Bluetooth) is a wireless technology standard that enables short-distance data exchange between fixed equipment, mobile equipment, and building personal area networks (it uses UHF radio waves in the ISM band of 2.4-2.485GHz). Bluetooth technology was originally created by telecommunications giant Ericsson in 1994 as an alternative to RS232 data lines. Bluetooth can connect multiple devices, overcoming the difficulty of data synchronization. [0003] Bluetooth smart lock is a new type of smart lock that has appeared in recent years. This kind of lock can be opened only by using a handheld smart device with Bluetooth function and matching related software. This kind of smart lock does not require the user to memorize the unlock password, nor does the user need to carry an RFID card for u...
