Intelligent lock authentication method, security chip, intelligent lock and management system thereof

Abstract

The embodiment of the invention relates to the technical field of safety, in particular to an intelligent lock authentication method, a safety chip, an intelligent lock and a management system thereof. The intelligent lock authentication method comprises the following steps: analyzing acquired unlocking authentication data, wherein the unlocking authentication data comprises a command code and a ciphertext part; determining a decryption key and an authentication rule of the ciphertext part based on the command code, wherein the decryption key and the encryption key of the ciphertext part are in a symmetric relationship or a dispersed relationship; decrypting the ciphertext part based on the determined decryption key to obtain an unlocking parameter; and authenticating the unlocking parameter based on the determined authentication rule. Meanwhile, the invention further provides a corresponding safety chip, an intelligent lock and a management system of the intelligent lock. According tothe embodiment provided by the invention, the data security of the security chip and the intelligent lock can be improved.

Description

technical field [0001] The invention relates to the field of security technology, in particular to an intelligent lock authentication method, a security chip, an intelligent lock and an intelligent lock management system. Background technique [0002] Under the background of smart cities and the construction of the Internet of Things, the application of electronic smart locks has become popular. At present, most of the common smart locks on the market lack security protection mechanisms, or the security mechanisms are relatively weak. The existing technology of smart locks has great security risks: [0003] 1. There is a problem of illegal modification of the attribute information of the smart lock; [0004] 2. Unauthorized electronic keys illegally obtain the authorization information of other keys to unlock the lock; [0005] 3. When the lock unlocking data is interacted, the lock authorization code is not protected and authorized by the hardware encryption algorithm ...

AI Technical Summary

Problems solved by technology

The existing technology of smart locks has great security risks:

[0003]1. There is an illegal modification of the attribute information of the smart lock;

[0004]2. Unauthorized electronic keys illegally obtain the authorization information of other keys to unlock the lock;

[0005]3. When the lock unlocking data is interacted, the lock authorization code is not protected and authorized by hardware encryption algorithm

[0006]The code and algorithm are easily cracked and leaked by the manufacturer's developers;

[0007]4. When it is necessary to strictly control the number of unlocking times, there is no protection authentication mechanism for the number of unlocking times, and there is a problem of multiple use of one authorization information

[0008]5. The lock unlock authentication transaction is complicated and the power consumption is huge
