Trust framework for calculating security strength of a cloud service

Abstract

Cloud Computing is a style of computing over the internet. It has a significant potential impact on every aspect of IT. The elastic nature of cloud makes it suitable for many types of organization. There are lots of benefits in moving towards the cloud. Along with the benefits, it also suffers from various obstacles that act as a barrier in its growth. Various obstacles are identified one of which is security of data and applications. Security concerns in cloud computing is an active area of research and experimentation. Many security solutions are identified and many are evolving. Trust is also identified as one of the solutions for providing security and selecting a particular service. Various trust solution are existing for many collaborative environments. We are focusing on trust based solution for achieving security in cloud computing. A trust framework is proposed that calculates the trust value. A trust value acts as a means for selecting any cloud service, providing a security strength evaluator for service provider and users in a cloud computing environment.
