An Advanced Secure Scheme of Domestic E-medical System in Body Area Network

Abstract

In the context of Body Area Network (BAN), e-medical service is gradually in high demand due to the increasing focus on health care recent years. However, there are still great challenges badly endangering medical information security. Designing for e-medical system, we propose a suit of well-integrated security scheme gathering functions of collecting, processing, diagnosing and querying medical data. Apart from resisting common attacks and eavesdropping from enemies, our proposed scheme borrows idea of dual signature in order to hide partial sensitive information from doctor, server and some other nice identities for privacy protection. In addition, we analyse the security performance of this e-medical system scheme and find it behaves well in resisting privacy disclosure, impersonation attack, replay attack and data falsification.
