Access layer safety algorithm processing method, system and device and storage medium

The invention provides an access layer safety algorithm processing method, system and device and a storage medium. The method comprises the following steps: a network node receives registration request information sent by a terminal equipment, and carries out the authentication of the terminal equipment according to the registration request information; after the authentication is passed, the network node determines a target safety algorithm list matched with the registration request information according to a preset mapping relation; the preset mapping relationship stores a first mapping relationship between the registration request information and the safety algorithm list; the base station determines a target safety algorithm based on a received target safety algorithm list sent by the network node; the base station and the terminal equipment perform bidirectional communication based on the target safety algorithm; according to the invention, differentiated safety protection can be provided for the network
