Cloud intelligent lock system based on multiple encryption mode and secret key management method

Abstract

The invention relates to a cloud intelligent lock system based on a multiple encryption mode and a secret key management method. The cloud intelligent lock system comprises an intelligent lock, a cloud management platform and a client, the intelligent lock is registered to the cloud management platform by adopting networking authentication registration through a NB-IOT (Narrow Band-Internet of Things) network, the client binds the authority information of fingerprints, an entrance guard card and bluetooth of a user in a matched mode according to the identity information of the user, the authority information is enabled to generate ciphertext to be sent to the corresponding intelligent lock through communication secret keys of the intelligent lock and an encryption algorithm, and the cloudmanagement platform adopts a secret key dispersing algorithm to disperse corresponding Managekeys so as to form modes of one lock to one secret key, one card to one secret key and one bluetooth to onesecret key. According to the cloud intelligent lock system based on a multiple encryption mode and the secret key management method, the intelligent lock is registered to the cloud management platform by adopting a networking authentication mode, so that networking of intelligent lock equipment is realized, centralized management is facilitated, particularly for hotels and public renting housings, personnel and safety management is facilitated, different encryption secret keys for different door opening modes and different encryption secret keys for the same door opening mode are adopted, andtherefore the safety is fully guaranteed.

Description

[0001] Technical field: The present invention relates to the technical field of smart locks, in particular to a cloud smart lock system and key management method based on multiple encryption modes. Background technique [0002] There are many types of smart locks currently on the market. In addition to common passwords, fingerprints, ordinary IC cards, and ID cards, there are also wireless door opening methods such as zigbee, wifi, and Bluetooth. However, these smart locks still have the following problems. Password, Fingerprints are entered by the front-end, and passwords and fingerprint information are stored locally. After information is entered, it is easy to lose and inconvenient to manage, and there are risks at the same time; the traditional IC card or ID card lacks an encryption mechanism, which makes it easy to be copied and has low security; wifi, Bluetooth or zigbee networking needs to add additional devices such as relay gateways, and there is a security risk of bei...

[0002] There are many types of smart locks currently on the market. In addition to common passwords, fingerprints, ordinary IC cards, and ID cards, there are also wireless door opening methods such as zigbee, wifi, and Bluetooth. However, these smart locks still have the following problems. Password, Fingerprints are entered by the front-end, and passwords and fingerprint information are stored locally. After information is entered, it is easy to lose and inconvenient to manage, and there are risks at the same time; the traditional IC card or ID card lacks an encryption mechanism, which makes it easy to be copied and has low security; wifi, Bluetooth or zigbee networking needs to add additional devices such as relay gateways, and there is a security risk of being cracked; the above-mentioned smart locks that open the door lack security encryption mechanisms. Although software and hardware communication encryption are also used, the data encryption method is single or The encryption processing content is single, and these smart lock devices exist independently, so it is impossible to network the smart locks, especially in the fields of public rental housing or serviced apartments, it is impossible to realize centralized management of smart locks and data information cannot be classified and controlled
