Key generation method and system and storage medium

Abstract

The invention provides a key generation method and system and a storage medium, and relates to the technical field of communication. The method comprises the following steps: under the condition that an initial channel is established between a satellite and a base station, the satellite performs first processing on first target data of the initial channel to obtain a first target sequence; and the base station performs second processing on the second target data of the initial channel to obtain a second target sequence. The first target sequence is the same as the second target sequence. The satellite generates a first secret key based on the first target sequence, the base station generates a second secret key based on the second target sequence, the first secret key is the same as the second secret key, and the first secret key and the second secret key are used for communication between the satellite and the base station, so that the problem of eavesdropping caused by the fact that an identity label is easily counterfeited in secret key interaction is solved.
