A Review of Privacy and Key Management Protocol in IEEE 802.16e

Abstract

IEEE 802.16e, as an amendment and corrigendum to the IEEE 802.16-2004, published on 28 February 2006, and intended to update and expand IEEE 802.16-2004 to allow for mobile subscriber stations. This paper summarizes the key management protocol belonging to security part of the IEEE 802.16e, which includes security negotiation, authorization, key derivation, handshake, and key transportation. While these building blocks are well designed, we point out some unwelcome features for these building blocks. We also give out suggestions to diminish the proposed problems. © Wuhan University Journals Press 2007.
