Re-Authentication Design for PKMv2 of IEEE 802.16e Standard

Abstract

Re-Authentication is required after the initial authentication in IEEE 802.16e to guarantee the security of the keys. We analyze the key factors in the re-authentication under the 5 authentication modes. And aiming at the RSA + Authenticated_EAP mixed mode, the re-authentication mechanism is designed. A PAK/PMK_counter is added into the PAK and PMK buffer, which can adjust the keys' lifetime to increase the switch frequency of the authentication methods.
