Abstract
Provided is a network equipment and an authentication and key management method for the same. The network equipment generates a Network Key (NK); the network equipment performs authentication protocol interaction with opposite communication equipment, and calculates a Basic Session Key (BSK) according to parameters for the authentication protocol interaction and the NK; and the network equipment calculates link Encryption Keys (EKs) used respectively for Media Access Control (MAC) and Physical (PHY) layers using various access technologies according to the BSK, and provides the EKs for respective MAC and PHY layer function modules. With the disclosure, the legality of the equipment is verified by performing an authentication process on the heterogeneous network equipments in one pass, and keys in various MAC layer technologies are managed in a unified way.
