Identity management in hybrid cloud

Cloud Computing is a platform that relies on sharing resources, software and information between remote servers and users over the network. Since cloud computing share distributed resources in open environment, it must be considered from privacy and security viewpoints. In this paper, we have discussed the security risks and concerns, key management, and mutual authentication of cloud computing. The paper also includes some models to tackle the challenges like regulatory, security and privacy to some extent. Next we discuss some solutions to mitigate these challenges along with a brief description on future work in cloud computing deployment.
