Primary key dynamic configuration system and method

Abstract

The invention discloses a primary key dynamic configuration method of a wireless communication device, and the method is applied to the wireless communication device, and comprises the following steps: sending primary key dynamic configuration request information to a response terminal; receiving a key algorithm selected from the primary key dynamic configuration request information sent by the response terminal and a random parameter generated by the response terminal; figuring out the primary keys according to the key algorithm and the random parameter; contrasting whether the primary keys calculated by the request terminal and the response terminal are consistent; and assembling the primary keys when the primary keys calculated by the request terminal and the response terminal are consistent. The invention also provides a primary key dynamic configuration system.

Description

technical field [0001] The invention relates to a system and method for dynamically configuring master keys of wireless communication equipment. Background technique [0002] With the continuous development of wireless communication technology, wireless communication devices have been widely used in daily work and life, such as wireless communication devices such as notebook computers, netbooks, handheld computers, and wireless routers. When wireless communication devices communicate with each other, due to the defect that the communication data is easy to be stolen and tampered with during the communication process, most of the wireless communication devices today use the method of communicating with both parties in the wireless communication process. The same master key generates a pair of temporary pairing keys to encrypt communication data for data communication, but most of the master keys of wireless communication devices are pre-configured before leaving the factory. ...

When wireless communication devices communicate with each other, due to the defect that the communication data is easy to be stolen and tampered with during the communication process, most of the wireless communication devices today use the method of communicating with both parties in the wireless communication process. The same master key generates a pair of temporary pairing keys to encrypt communication data for data communication, but most of the master keys of wireless communication devices are pre-configured before leaving the factory. The key method is prone to the problem of master key leakage. Once the master key is leaked, it will lead to security threats to the shipped products during the communication process.
