Ensuring Higher Security In Distributed Accountability For Data Sharing on The Cloud

With the rapid development of cloud services, the data is share in a friend circle in the cloud computing environment. Since it is not feasible to implement full security, access control becomes a challenging task, especially when we share sensitive and confidential data on cloud servers. To resolve this problem, we propose a key-policy attribute-based encryption with KP-TSABE scheme, a novel secure data self-destructing scheme in cloud computing. Also we propose the JAR programmable abilities to both create a dynamic and moving object, and to ensure that any access to users’ data will trigger verification and automated logging local to the JARs. In the KP-TSABE scheme, every cipher text is labelled with a time interval while private key is used with a time instant. The cipher text can only be decrypted if both the time instant is in the allowed time interval and the attributes along with the cipher text verify the key’s access structure. The KP-TSABE scheme is support to solve many important security problems by supporting user-defined authorization period and by providing fine-grained access control.
