Ensuring accountability for application sharing in the cloud

Cloud is a host based network service on the basis of service over internet. When large number of users shares the applications for uploading, downloading and access control, then there will be hazard of fraud access in the network. If accountability is improved, then due to some accountability constraint, system performance reduces. Here we propose the Push Pull key matching algorithm which performs accountability and also improves the performance of system by 56% than existing system. The cloud accountability framework is designed which consist of registration manager, log manager and actual application. Registration manager performs the service level agreement which is done by cloud service provider. When cloud service provider registers, then he gets the key of UID and IP address. Accordingly the log manager built a key and Push this key securely by encryption process. In encryption process, temporal attribute base encryption and advanced encryption standard is used for security purpose. The application filter is used to performing access role of the system. These roles are assigned by cloud service provider after completing service level agreement.
