A Star-Topological Privacy Encryption for Telecare Medical Information Systems
Jing Li, Licheng Wang, Xinxin Niu · 2016
In the telecare medical information systems, the sensitive data of patients are closely related to their privacy. A sound remote transaction processing system for server-clients (one to many) structure is urgently needed. In this paper, a diagram of privacy encryption that features a star-like topology is introduced. Security requirements are presented by an adhoc manner. We proposed a concrete star-topological encryption scheme based on some reasonable hardness assumptions from computational group theory. The scheme achieves the confidentiality and non-repudiation of the delivered messages for server and clients. Therefore, these characteristics guarantee privacy for each client and prevent malicious attacks. Besides, our scheme is efficient, especially for batch processing.
