AN AUTHENTICATIVE WAY TO DATA TRANSMISSION FOR CLUSTER BASED WIRELESS SENSOR NETWORK

Abstract

Due to wireless nature of sensor network, secure data transmission is a major issue for wireless sensor network. Clustering is a technique which increases network lifetime and reduces power consumption of sensor nodes in WSN. In this paper, we study an authenticative way to data transmission for cluster based WSN. We propose two protocols for authentication of data, those are secure and efficient data transmission protocols SET-IBS and SET-IBOOS, by using identity-based digital signature (IBS) scheme and identity-based online and offline digital signature (IBOOS) scheme. This protocol relies on ID-based cryptography. SETIBOOS further minimize the computational overhead. Our result show that performance of proposed protocols are better than existing secure protocols.
