An Id-based Multiple Authentication scheme against attacks in wireless sensor networks

A wireless sensor network (WSN) consists of a number of tiny, low-cost, and resource-constrained sensor nodes, but is often deployed in unattended and harsh environments to perform various monitoring tasks. Therefore, WSN is venerable to various attacks. Among these attacks, the id-based attack such as node replication attacks and Sybil attacks are the most threatening. Hence, the security in WSNs presents a critical challenge for identity and data authentication. Although there are some recent approaches, most are resources-costing or constrained to some specific systems. Thus, in this paper, we present a novel authentication scheme to prevent these attacks. This Id-based Multiple Authentication (IMA) scheme bases upon the joint identity authentication and steganography to present a secure mechanism for data aggregation in WSNs. Simulations against above-mentioned attacks applying this scheme is presented and consequently show that the scheme can successfully authenticate the sensory data with high confidentiality.
