Abstract

Secure data transmission is a critical issue for Cloud computing networks. Clustering is an effective and practical way to enhance the system performance of cloud. Paper provides study about a secure data transmission for cluster-based cloud (CCNs), where the clusters are formed dynamically and periodically. The paper proposes two Secure and Efficient data Transmission (SET) protocols for CCNs, called SET-IBS and SETIBOOS, 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 Cloud, while its security relies on the hardness of the discrete logarithm problem. The paper shows 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. The expected results of using the proposed protocols is the increase in performance of the existing secure protocols for CCNs, in terms of security overhead and energy consumption.
