摘要：With the fast improvement of flexible cloud services it becomes progressively powerless to utilize cloudservices to share information in a friend circle in the cloud computing condition. Since it is not practical to implementfull lifecycle protection security, access control turns into a testing task, particularly when we share sensitiveinformation on the cloud serverss. In the KP-TSABE plot, each ciphertext is set apart with a period interval whileprivate key is connected with a period minute. The ciphertext must be decoded if both the time minute is in thepermitted time interval and the properties related with the ciphertext satisfy the key's get the chance to structure. Thesensitive information should be securely self-destructed after a client determined close period.
