Secure and Efficient Data Transmission for Cluster-Based Wireless Sensor Networks

摘要: Secure data transmission is a critical issue for wireless sensor networks (WSNs). Clustering an effective and practical way to enhance the system performance of WSNs. In this paper, we study secure cluster-based WSNs (CWSNs), where clusters are formed dynamically periodically. We propose two efficient (SET) protocols CWSNs, called SET-IBS SET-IBOOS, by using identity-based digital signature (IBS) scheme online/offline (IBOOS) scheme, respectively. SET-IBS, security relies on hardness Diffie-Hellman problem in pairing domain. SET-IBOOS further reduces computational overhead protocol security, which crucial WSNs, while its discrete logarithm problem. show feasibility with respect requirements analysis against various attacks. The calculations simulations provided illustrate efficiency proposed protocols. results that have better than existing terms energy consumption.
