Abstract: The utilisation of cloud services in today’s technological field is booming. People increasingly use cloud services for the purpose of sharing data. Hence there is a need to secure the sensitive data that is being shared through cloud servers. Providing a full life-cycle privacy security is not feasible, as it does not allow for access control. In order to provide a solution for this problem we put forward ‘key-policy attribute-based encryption with time specified attribute’- a secure data self destructing scheme which can be implemented in cloud servers so as to provide complete security to the sensitive data that is being transferred via cloud services. In this scheme, every cipher-text is associated with a time interval while private key is associated with a time instant.It is possible to decrypt the cipher-text only if both the time instant is within the specified time interval and the attributes associated satisfy the access structure of the key. The major advantage of this scheme over others is that it supports user-defined authorisation period and provides a fine-grained access control. The sensitive data gets self-destructed when the user specified time gets expires.
