Highly Efficient Privacy-Preserving Key Agreement for Wireless Body Area NetworksKey Agreement Protocol • June 15th, 2018
Contract Type FiledJune 15th, 2018Wireless Body Area Networks (WBANs) consist of miniaturized computing devices which can be fitted inside or around the human body. Through use of short range communication technologies, these devices talk to a designated centralized node (Hub) which further communicates with external networks via a Gateway. Mindful of the peculiarities of communicating in and around the human body, the IEEE published IEEE Std 802.15.6 for WBAN communications in 2012. In addition to conventional security guarantees, privacy is of utmost importance for typical target application areas such as healthcare and the military. The security of traffic in IEEE Std 802.15.6 is protected using authenticated encryption, which requires the establishment of symmetric session keys. The procedure for agreeing these keys is thus critical to the overall security and privacy of a WBAN.
