Secure and Efficient Data Transmission for Cluster-based Wireless Technology Networks

Secure data transmission network is a decisive issue for wireless technology networks (WTNs). Clustering is an effective and practical way to enhance the system performance & methods of WTNs. In this respective paper, we study a secure data transmitted for cluster-based method of WTNs (CWTNs), where the clusters are formed dynamically and periodically. We propose two Secure and Efficient data Transmission (SET) protocols for CWTNs, 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 WTNs, 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 results show that, the proposed protocols have better performance than the existing secure protocols for CWTNs, in terms of security performance overhead and energy consumption.
