Trusted and Reputed Services Using Enhanced Mutual Trusted and Reputed Access Control Algorithm in Cloud

Abstract

In cloud computing, trust management is more important when providing users with virtualized and scalable web services. Many existing systems sharply divide trust value into right or wrong. Trust means an act of faith; confidence and reliability in something that is expected to behave or deliver as promised. Trust is required to solve the problem created due to uncertainty and vulnerability caused by open conditions of cloud computing. This paper presents a mutual trust for both cloud users and cloud service providers to avoid security related issues in cloud computing. This is to be done by providing trusted services to the cloud users using enhanced mutual trust to be known as Enhanced Mutual Trusted Access Control Algorithm (EMTACA). This paper proposes the model which considers both the cloud user's behavior trust and cloud service provider's credibility. Trust calculations are based on the behavior which includes history of direct communication between both the user and service provider; based on friends and third party recommendations. The hierarchy based reputation systems has suggested how to safeguard the data objects in the level of file access which ensures the cloud security. The different security measures are used to protect the different cloud services. This proposed system which includes the EMTACA algorithm can assure enhanced, guaranteed and trusted and reputation based cloud services among the users in a cloud environment.
