Problems solved by technology

[0005] Because the traditional key is very inconvenient to carry, and it is prone to loss or theft
As for the existing electronic key, in some cases where other personnel are required to use the key temporarily, the corresponding smart lock can only be opened after the information is authorized first, an...

Embodiment Construction

[0018] The generation and identification scheme of the electronic key is described according to the drawings.

[0019] 1. System initialization and user electronic key generation, see figure 1 and image 3 .

[0020] The key pair (x i ,y i ), private key x i Stored in the user account software on the mobile device. When the user makes a reservation through the Internet, checks in at the front desk, transfers the house, or confirms that the user has the right to use the room, he will register through the building management system, store the user identity information in the corresponding smart lock storage unit, and pass the system Find the account's public key y i Stored in the corresponding room smart lock storage unit.

[0021] When the user account software receives the assigned private key, the software automatically initializes the key generation flag list, according to the personal information of the user account, and sets the key type as the user's long-term key ...

Abstract

The invention relates to a method for encoding information of a user and generating a two-dimension code digital key by adopting a digital signature technique. A mobile phone and other mobile devices are taken as carriers of the two-dimension code digital key. The method comprises steps as follows: a credible key generation center allocates a unique private/ public key pair for a user account and a smart lock storage unit during starting; a digital signature algorithm is adopted, that is, a private key is used for encrypting the information of the user and a public key is used for decrypting a read-in two-dimension code sequence; the information of the user is stored and read by field. Normal use of the two-dimension code key of the user can be guaranteed, the reliability and the authenticity of the source of a generated temporary two-dimension code key can be guaranteed, meanwhile, temporary two-dimension code keys received by different people can be effectively distinguished, and the flexibility and the safety of a whole two-dimension code smart lock system are unified.

Description

technical field [0001] The invention belongs to the technical field of intelligent locks, and relates to a method for processing user's identity information into a two-dimensional code electronic key, using digital signature technology to ensure the reliability of its source, and utilizing the comparison of validity fields to realize a one-time effective method of a temporary key. Background technique [0002] A two-dimensional code is a black and white graphic that uses certain specific geometric figures distributed on a plane according to certain rules to record data symbol information, and can store a certain amount of alphanumeric image content. [0003] Digital signature is the use of public key encryption technology to perform cryptographic transformation on the data unit and attach it to the data unit. By decrypting the additional data, the source and integrity of the data unit can be verified. Digital signature has the functions of identity authentication, encrypted ...
