A Secure Message Integrity in Cloud Computing with Combined Cryptographic Approach
Abstract: Message authentication ensures that there is no modification, deletion, insertion or replay of shared data. Today, millions of users sharing resources on internet through cloud computing. Providing integrity of shared data among data owner and data user is a major issue. Many research works is carried out related to message integrity, but still there is a lack of security interns of message authentication between data owner and cloud user. In this paper, we implement a technique, where data owner wants his message to be private so that the cloud user can access it. The proposed work comprises of different technique and procedures that ensure data protection. We commence with message integrity and confidentiality. The SHA1 and SHA2 are used for integrity check of data, Bluefish algorithm is for confidentiality. The owner wishes to do modification on stored data if necessary only by providing or regenerating message digest value on cloud platform.
