Secure Mutual Authentication for Cloud Environment

Cloud computing is a service oriented technology which provides various services to users which vary from software to hardware. However, ensuring the security in cloud computing environments is one of the most challenging issues. In cloud, when two parties communicate with each other, mutual authentication is needed for secure communication. This paper proposes a secure mutual authentication model for cloud environment. The authentication is handled by software-as-a-service application (ASaaS). Modified Diffie Hellman agent (MDHA) is used to provide mutual authentication which interacts with ASaaS instead of cloud server. The scheme provides authentication by using a four step process. Another agent named cryptography agent is used to provide encryption of data before uploading on the cloud. According to the analysis of the proposed scheme, it is resistant from many attacks like Man in the Middle attack.
