Trust based Reputation Framework for Data Center Security in Cloud Computing Environment
S. Baghavathi Priya, R.S. Ponmagal · 2023
A modern method of accessing and using computer resources on the Internet is through the usage of cloud computing. Contrary to the conventional Internet, there are certain security concerns and vulnerabilities related to confidentiality, integrity, and availability. Most of the current trust management system models do not fully account for the relevance of interactions, which hinders the accuracy of the trust ratings and needs to be fixed. In this paper, Trust based reputation framework for data center security in cloud computing environment is proposed. In this framework, each DCs reputation values are determined independently from the trust degrees of its servers. The level of each server's trust is computed based on the Interaction Efficiency (IE), Service Satisfaction Index (SSI) and Service Response Delay (SRD). During the transmission from DC to user, the user evaluates the reputation of the serving DC and ignores if the reputation is low. Simulation results using Cloudsim indicate that the proposed TRF-DCS has lower computation cost and service access delay with higher correctness of data and service success rate.
