Group Authentication in Wireless Sensor Networks

Khyati Chaudhary, Gitanjali Shinde

Abstract: Group authentication is used to authenticate multiple devices at once. This is used for group oriented applications. As nowadays a use internet is growing day by day. We need secure authentication for devices for communication. So we are connecting devices in wireless media. One group manager is there. Our proposed scheme is decreasing task of devices and group manager. Using paillier threshold cryptography we authenticate devices. we let group manager calculate value of H(SS). Devices have no need to collect all partial decrypted messages and calculate value of hash. Group manager will provide a pass key to avoid devices requests who want to communicate. In this way, a robust scheme provide secure and novel group authentication scheme to authenticate devices.
