The key of security encryption matrix contact type electronic lock

Abstract

The invention relates to a security encryption matrix contact type electronic lock key and relates to the field of electronic locks. The key comprises a matrix key board and a key casing, wherein a fingerprint module and a display screen are arranged on the lateral edge of the key casing, and a control button is arranged at the upper end of the key casing; a key MCU is arranged in the key casing,and the key MCU is respectively connected with a power management module, a storage module, a fingerprint module, a contact communication module, a Bluetooth module, an anti-disassembled detection module, a driving motor module and a display and sound module; after verification of the fingerprint module, the driving motor module is started to pop the matrix contact key out; after detection error times of the fingerprint module exceed preset times, password files stored in a FLASH are automatically formatted; thus, the problems of safely encrypting the electronic lock and preventing the electronic lock from being cracked for procedures or chip interfaces are solved, physical encryption can prevent a password of the electronic lock from being cracked through the interfaces, the electronic lock is effectively prevented from being unlocked violently, and data cracking unlocking prevention is improved based on preventing technological unlocking.

Description

technical field [0001] The invention relates to the field of electronic locks, in particular to a key for a security encryption matrix contact type electronic lock. Background technique [0002] In the era of vigorous development of electronic locks, most electronic locks discard traditional keys for convenience, and must rely on electricity for fingerprint, keyboard input, pupil, and face recognition verification. Considering that the safety and convenience of security equipment need to exist at the same time, in some specific scenarios, it is unrealistic to only use active electronic locks and completely rely on electric power supply, so passive electronic locks have emerged as the times require, and have the ability to store unlocking keys The data protection of passive electronic locks is becoming more and more important. The key stores the important ciphertext data required for unlocking. If it is lost or cracked, all security and anti-theft will be useless. Contents ...
