A Secure Document Self-Destruction Scheme: An ABE Approach

Today's personalized and newfangled services and legal landscape put forward formidable challenges to personal data privacy security in cloud computing. In this paper, we propose an ABE-based secure document self-destruction (ADS) scheme, which is a novel integration of attribute-based encryption (ABE) algorithm with global-scale, decentralized distributed hash table (DHT) network. Specifically, the ADS scheme is able to protect the privacy security of past, archived sensitive documents, and make sure that all copies of those documents become unreadable by making them automatically destructed after a user-specified time. The security and performance analysis shows that the ADS scheme not only resists various possible attacks, but also supports flexible access control policies for sensitive documents during their lifetime.
