A broadband cognitive wireless communication method and system

Abstract

The invention discloses a broadband cognitive wireless communication method and system. The method includes the following steps: based on an authentication request, two nodes to be connected respectively obtain the IDs of the other party after being encrypted by the connection authentication key, and based on the obtained IDs Perform connection access authentication; wherein, the step of obtaining the connection authentication key includes: obtaining three parameters of a timestamp, a center frequency point and a preset channel bandwidth at the time when the authentication request is issued, and using a first preset master key encryption algorithm Perform encryption operation on the obtained three parameters to obtain the connection authentication key; obtain the connection access authentication result, when the connection access authentication result is successful, encrypt the data information to be transmitted after the connection access authentication is completed. transmission between the two nodes. The method disclosed by the invention can guarantee one or more of node security, connection security and information transmission security by using dynamic encryption security means.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, relates to the field of wireless communication security encryption, in particular to a broadband cognitive wireless communication method and system. Background technique [0002] With the rapid development of digitalization and intelligence in the power industry, wireless communication equipment with high security is urgently needed; however, the power industry does not have a dedicated continuous spectrum, but it needs to transmit high-bandwidth services such as video and images in real time, which requires a complete confidentiality, security, and reliability. [0003] At present, traditional broadband wireless communication systems based on 3GPP (the 3rd Generation Partnership Project) and IEEE (Institute of Electrical and Electronic Engineers, Institute of Electrical and Electronics Engineers) standards use licensed dedicated spectrum or shared Spectrum, supports fixed channel...

Problems solved by technology

[0004] Based on the existing dynamic encryption method, it cannot solve the above-mentioned defects caused by the static key encryption method. The main reason is that many of the existing dynamic encryption methods use the method of generating random numbers and broadcasting the random numbers. , and then the transceiver formulates an encryption method according to the random number, but this method requires a special module for generating random numbers, and the random numbers are easily leaked during the broadcast process, so the security is also threatened
