Description: TOPIC: A SECURE AND EFFICIENT KEY GENERATION AND AGREEMENT METHOD FOR WIRELESS BODY AREA NETWORKS

LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A

ABSTRACT:
With wide deployment of Wireless Body Area Networks (WBAN), security becomes one of the major challenges to WBAN research due to the broadcasting nature of WBAN, especially when sensitive patient information is exchanged among nodes of WBAN. Encryption is the basic method of securing wireless communication link. In general, the more key bits are used, the stronger the encryption key is. Key generation and agreement are two of the major research topics of WBAN communication, and secure and efficient key generation and agreement methods are required by WBAN.

In this project, I proposed a new key generation method and a new key agreement method. The new key agreement method increases the key generation rate multiple times with the helps from the neighbor nodes. Overall it consumes a little bit more energy but speeds up the key generation procedure and avoids deployment of extra hardware (e.g., antenna). The new key agreement method improves the Improved Juels and Sudan (IJS) algorithm to achieve higher performance in data encoding. Also it improves the Reed-Solomon decoding algorithm to tolerate least significant data differences by intensifying local computation instead of passing more check symbols to the other side.
