Abstract: Disclosed is an apparatus and method for generating a security key in a mobile communication system that performs security key generation. An Authentication, Authorization and Accounting (AAA) server generates a Master Session Key (MSK) and an Enhanced MSK (EMSK) from a Long Term Credential key, and a Device-MSK (D-MSK), a User-MSK (U-MSK) and a Device and User-MSK (DU-MSK) from the MSK and the EMSK. An Access Gateway (AG) generates a Root-MSK (R-MSK) from the MSK and EMSK received from the AAA server. A Signaling Radio Network Controller (SRNC) generates a Pairwise Master Key (PMK) from the R-MSK received from the AG, and a Traffic Session Key (TSK) from the PMK. A Base Station (BS) sets up a radio connection to a Mobile Station (MS) using the TSK received from the SRNC, and performs radio communication using the set radio connection. The MS generates an MSK and an EMSK, and generates there from a D-MSK, a U-MSK, a DU-MSK, an R-MSK, a PMK, an SRK and a TSK, to perform radio communication with the BS.

Abstract: A method and apparatus for performing device authentication and user authentication in a mobile communication network are provided. A connection is established between an MS and an SRNC that controls communications of the MS through a BS. The SRNC receives a D-MSK for device authentication of the MS from an AAA server that has completed an EAP negotiation with the MS and stores the D-MSK by the SRNC, when the BS triggers an EAP authentication after the connection establishment. The SRNC receives an R-MSK from an AG and stores the R-MSK after the connection establishment. The R-MSK is generated using a U-MSK for user authentication of the MS received from the AAA server by the AG. The SRNC generates a PMK for use during a session using at least one of the D-MSK and the R-MSK, and one of the BS and the SRNC generate a key set using the PMK, for use in at least one of data encryption, data integrity check, and session management during the session.
