基于CP-ABE实现隐私保护的远程医疗诊断系统

Telemedicine scheme for wireless body area networks with privacy protection based on CP-ABE

随着无线体域网应用的推广,隐私保护成为无线体域网安全领域的研究热点.本文提出了一种基于CP-ABE实现隐私保护的远程医疗诊断方案,实现病人的匿名问诊,病人可以在发起远程医疗诊断请求前设置医生的访问控制权限来完成分级隐私保护.同时采用医护服务器为病人终端承担加密计算,大幅降低病人终端开销,实现了远程医疗系统的保密性、真实性、完整性与可跟踪性等安全特性.理论分析和性能分析结果表明本方案具有较少的计算开销和通信开销,在安全性和性能上都可适用于无线体域网的应用场景.

With the promotion of the application of Wireless Body Area Network （WBAN） , privacy protection has become a research hotspot in the field of WBAN security. This paper presents a privacy protection scheme for Telemedieine System based on WBAN. The temporary identity is utilized to realize anonymous consultation; the patient can set access control authority rule for a doctor before initiating a remote medical diagnosis request to realize hierarchical privacy protection. At the same time, the medical server is assigned to undertake the enelTption computation for the patient terminal,it greatly reduces the computation cost and communication cost of the patient terminal. Security t）atures including confidentiality, authenticity, integrity and traceability are assured. Performance analysis shows that the proposed scheme, which can reduce the computing cost and communication cost, is applicable to WBAN applications in terms of security and performance.
