A Study of IEEE 802.15.4 Security Framework for Wireless Body Area Networks

摘要: A Wireless Body Area Network (WBAN) is a collection of low-power and lightweight wireless sensor nodes that are used to monitor the human body functions surrounding environment. It supports number innovative interesting applications, including ubiquitous healthcare Consumer Electronics (CE) applications. Since WBAN collect sensitive (life-critical) information may operate in hostile environments, they require strict security mechanisms prevent malicious interaction with system. In this paper, we first highlight major requirements Denial Service (DoS) attacks at Physical, Medium Access Control (MAC), Network, Transport layers. Then discuss IEEE 802.15.4 framework identify vulnerabilities context WBAN. Different types on Contention Period (CAP) Free (CFP) parts superframe analyzed discussed. observed smart attacker can successfully corrupt an increasing GTS slots CFP period considerably affect Quality (QoS) (since most data carried period). As increase attackers corrupted eventually increased, which prevents legitimate utilize bandwidth efficiently. This means direct adaptation for not totally secure certain New solutions required integrate high level
