Base station authentication method and device

Abstract

The invention discloses a base station authentication method and device, and belongs to the technical field of communication. The base station authentication method comprises the steps: broadcasting acredibility evaluation request to a blockchain network, wherein the credibility evaluation request comprises a blockchain identifier of a current micro base station, a blockchain identifier of a terminal, a terminal mobile phone number and deadline; receiving a credible evaluation result returned by the micro base station except the current micro base station in the blockchain network and a blockchain identifier of the micro base station, the credible evaluation result comprises a credible evaluation value of homomorphic encryption, and the credible evaluation value is a numerical value obtained based on a historical connection record of the micro base station and the terminal mobile phone number; calculating a credible evaluation average value based on the credible evaluation result, anddetermining whether to allow the terminal to access according to the credible evaluation average value. According to the base station authentication method, the reliability and legality of the to-be-accessed terminal of the micro base station are verified, and the security of a communication network can be ensured to a certain extent.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a base station authentication method and device. Background technique [0002] With the development of communication network technology, the speed of network upgrading is getting faster and faster, and mobile communication technology has also developed from the first generation of mobile communication technology in the 1980s to the fifth generation of mobile communication technology today. People have entered the 5G (5th-Generation) communication era. Compared with previous generations of mobile communication technologies, the data transmission speed and data transmission quality in 5G mobile communication technology have been greatly improved, thereby improving user perception. However, in addition to paying attention to data transmission speed and transmission quality, people are also increasingly aware of the importance of communication security. Therefore, op...
