Abstract
As various applications of wireless ad hoc network have been proposed, security has become one of the big research challenges and is receiving increasing attention. The present invention provides for a distributed key management and authentication approach by deploying the recently developed concepts of identity-based cryptography and threshold secret sharing. Without any assumption of pre-fixed trust relationship between nodes, the ad hoc network works in a self-organizing way to provide the key generation and key management service, which effectively solves the problem of single point of failure in the traditional public key infrastructure (PKI)-supported system. The identity-based cryptography mechanism provided not only to provide end-to-end authenticity and confidentiality, but also saves network bandwidth and computational power of wireless nodes.
