Abstract

The invention discloses a method and a system for encrypting hardware based on proximity card unlocking, and a smart cloud lock. The method comprises the following steps: step A, when a proximity cardcontacts the smart cloud lock, the MCU processor of the smart cloud lock identifies a sensing SN code in the proximity card, and sends a verification instruction to a security chip; step B, the security chip receives the verification instruction, and sends a security verification code to the MCU processor; and step C, the MCU processor packs the acquired sensing SN code and the security verification code into an unlocking request data packet, and sends the unlocking request data packet to a cloud server. An encrypted unlocking instruction sent by the cloud server, and is decrypted by the security chip, so the unlocking instruction is prevented from being stolen, the anti-theft performance is improved, and a problem that the unlocking instruction recorded in the proximity card can be easily stolen is avoided.

Description

technical field

[0001] The invention relates to the field of intelligent door lock devices, in particular to a hardware encryption method and system for unlocking based on an induction card, and an intelligent cloud lock. Background technique

[0002] At present, many families install smart door locks for anti-theft doors, and use passwords, proximity cards, fingerprints, etc. to open the door instead of keys. It is more convenient, faster, safer and more reliable to open the door at home. And with the development of Internet technology, smart door locks can be connected to the Internet so that users can control them through mobile terminals such as mobile phones and computers, so that smart door locks can be upgraded to smart cloud locks. However, the existing smart door locks directly record the unlocking instructions on the proximity card, and thieves can easily steal the unlocking instructions from the proximity card, thereby unlocking through the stolen unlocking instru...
