Distributed Trust Relationship and Polynomial Key Generation for IEEE 802.16m Networks

Mobile relay stations (RSs) provide broadband wireless access (BWA) networks with additional mobility, which extends network coverage and advances dynamic networking and ubiquitous computing. However, there are many unresolved security vulnerabilities in the current IEEE 802.16 standard, such as BS/RS spoofing. Additional measures are needed to ensure that each component in the network is a trusted entity, verified by a trusted server and accessible through secure private channels. We suggest a distributed trust relationship (DTR) with polynomial-based key generation as a way of mutually validating trustworthiness between network components and preventing compromised components from infecting the entire network.
