Secure information transaction in hybrid cloud computing

Hybrid cloud is the combination of public cloud and private cloud as per the security of information in the private cloud is very essential. Proposed scheme of security is to provide two different set of keys to the private and public cloud users, with that keys private cloud users are given privilege to access public cloud too. The keys will be changed whenever the change in user occurs. Initially public cloud users and private cloud users are segregated in a tree structure for easy and secure key transaction and information transaction.
