Secure and Efficient Data Transmission for Cluster-Based Wireless Networks

ABSTRACT: Novel advance in wireless communications and electronics have led to the development of low-cost, low power and multifunctional small smart sensors. These sensors have the ability to sense, process data and communicate with each other via a wireless connection. Collection of a large number of these sensors is known as a wireless sensor network (WSN). In wireless sensor networks nodes are deployed to detect events or environmental phenomena by sensing, processing and forwarding data to an interested user. Clustering is an effective and practical way to enhance the system performance of WSNs. In this paper, we learn a secure data transmission for cluster-based WSNs (CWSNs), where the clusters are formed dynamically and periodically. We propose two Secure and Efficient data Transmission (SET) protocols for CWSNs, called SET-IBS and SET-IBOOS, by using the Identity-Based digital Signature (IBS) scheme and the Identity-Based Online/Offline digital Signature (IBOOS) scheme, respectively. In SET-IBS, security relies on the hardness of the Diffie-Hellman problem in the pairing domain. SET-IBOOS further reduces the computational overhead for protocol security, which is crucial for WSNs, while its security relies on the hardness of the discrete logarithm problem. We show the feasibility of the SET-IBS and SET-IBOOS protocols with respect to the security requirements and security analysis against various attacks. The calculations and simulations are provided to illustrate the efficiency of the proposed protocols
