Provably Secure Online/Off-line Identity-Based Signature Scheme for Wireless Sensor Network
Source: King Abdulaziz University
This paper describes an efficient and secure online and off-line signature scheme for Wireless Sensor Network (WSN). Security of the proposed scheme is based on difficulty of breaking Bilinear Diffie-Hellman Problem (BDHP). WSN systems are usually deployed in hostile environments where they encountered a wide variety of malicious attacks. Information that is the cooked data collected within the sensor network is valuable and should be kept confidential. In order to protect this transmitted information or messages between any two adjacent sensor nodes, a mutual authentication and key establishment protocol is required for wireless sensor networks.
