Server-Based Secure Key Management for the IEEE 802.15.6 standard

摘要: Wireless Body Area Networks (WBANs) connects a variety of sensor nodes that operate in close vicinity to, on or inside human body. Recently, the IEEE Task Group 6 has established first international WBANs standard, called 802.15.6. Since some communications can carry sensitive information, standard provides for strong security by association procedure identifies WBANs' and Network Coordinator (BNC) to each other. However, many vulnerabilities are noticed above procedure, especially Key Compromise Impersonation (KCI) attacks. In this paper, we design secure key management authentication scheme, Server-Based Secure Management 802.15.6 (SBSKM). The objective proposed scheme is improve ensuring encryption all communications, starting from beginning procedure. To end, extended architecture with trusted server, responsible creation, initialization, distribution keys as well guarantee identity joining network. Over Castalia simulator based OMNeT++, expanded simulations have been performed results show robustness our solution which, one hand, allowed us overcome lack confidentiality other it doesn't lead reduction standard's performances.
