Embodiment Construction

[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0022] refer to figure 1 As shown, one embodiment of the present invention is a mobile phone door lock system based on an asymmetric key, the system includes a smart phone, a door lock and a server, and data transmission is performed through a network between the smart phone, the door lock and the server ,in:

[0023] The server is used to store the mobile phone serial number blacklist, and after the verification is legal, the data string of the door opening authority is encrypted and sent to the smart phone;

[0024] The smart phone is used to send the door-opening authority data string of the machine to the door lock, and the door-opening authority data string at least includes the door lock ID and the mobile phone serial number;

[0025] The door lock is used to decrypt the current door-opening permission data string, and judge whether the decrypted data string c...

Abstract

The invention discloses a mobile phone door lock system based on an asymmetric secret key and a realization method thereof, and belongs to a mobile phone door lock. The system comprises an intelligent mobile phone, a door lock and a server; data transmission among the intelligent mobile phone, the door lock and the server is carried by network; the server is used for storing a mobile phone identification number blacklist, and encrypting door opening permission serial data after the verification is valid and sending the serial data to the mobile phone; the intelligent mobile phone is used for sending the door opening permission serial data of the mobile phone to the door lock, and the door opening authority serial data at least comprises a door lock ID, a mobile phone identification number, etc.; the encrypted permission serial data and black list verification and multiple encryption and decryption verifications are carried out between the mobile phone, the door lock and the server, thereby solving the technology problem that the prior mobile phone door lock product cannot withstand replay attack and the invalid unlocking risk is high, providing a complete permission distribution, authentication and cancel process, greatly improving safety performance of the mobile phone door lock product, and promoting the development of the mobile phone door lock industry.

Description

technical field [0001] The present invention relates to a mobile phone door lock, more specifically, the present invention mainly relates to a mobile phone door lock system based on an asymmetric key and its implementation method. Background technique [0002] At present, there are very few mobile phone door lock products. The inventor’s reverse analysis on the market shows that their door opening process is roughly as follows: the mobile phone and the door lock share a door opening password, and the mobile phone sends this password to the door lock when the door is opened. open the door. There are serious security problems in this door opening process, which cannot resist replay attacks. The attacker only needs to monitor the door opening password and then replay it to open the door; therefore, it is necessary to study and improve the anti-theft function of this type of door lock product. Contents of the invention [0003] One of the purposes of the present invention...
