USE OF DSS WITH STATION TO STATION KEY AGREEMENT AND CLOUD MANAGER TO ENHANCE SECURITY IN CLOUD COMPUTING

Abstract

Cloud computing provides IT as service. Cloud computing is a budding paradigm having high availability, performance, least cost and many others. Cloud is an IT environment based on remotely providing IT resources. As cloud computing is an internet based computing solution, there are lots of security breaches and vulnerabilities like authenticity, data security, confidentiality and privacy which should be dealt properly to get high performance. Different combinations are used by different researchers to get rid of these security breaches and vulnerabilities, same way we have chosen a combination of authentication technique and key exchange with cloud manager. In this paper we have proposed a model to enhance security of cloud by using Station to Station key agreement for generating session key with a fixed timestamp between User and Cloud Server and then send request for any service by using Digital Signature Standard, the request message would be encrypted by using that session key which was shared earlier and once a session key is been used then that session key would not be used again. So every time for any service new session key is required by user. All of these issues related to authentication and authorization are handled by a cloud manager present between cloud server and user.
