Abstract |
Attribute based encryption has been widely applied for secure data protection in PHR systems. However, since different users may share the same attributes in the system, a user may leaks his private key for illegal data sharing without being detected. This will add more threat to the private data stored in PHR system. To help users achieve higher efficiency and more secure data sharing in mobile PHR system, based on previous works, we study the traitor tracing mechanism in attribute based cryptosystem and propose a high efficient attribute based encryption with user accountability in mobile PHR system. If a malicious PHR user exposes his private key for illegal data sharing, his identity can be accurately pinpointed by the system manager. During the whole process of data sharing, no bilinear pairing operations are needed, hence this will the mobile terminal devices from heavy computation burden. As a further study, in this short report, we show that using a novel attribute based encryption with user accountability can help users achieve better efficiency and more secure data sharing in mobile PHR system. |
