Management of trust is one of the most challenging parts in cloud computing. Cloud service’s features such as distributed, dynamic and nontransparentintroduces several challenges for availability, privacy, and security. A method is proposed to have trust as a service between cloud serviceprovider and customer by creating a cloud armor. This proposed methodology is used to make cloud server end and customer end system secure ofany intrusion to their privacy. In this methodology, we will have a user usage pattern log as ever user has its own unique way of using his/her system;hence, in case if any odd user pattern is being encountered it will automatically block the system and simultaneously shoots a message as well as a callto the user notifying him/her about this unauthorized access. This log is set a various small pattern log, for example, keylog, preferable website visited,and time of accessing the system. Further, we have secured these logs using Rivest-Shamir-Adleman algorithm with very large key size.
