摘要
无线体域网和云平台的结合使得数字化医疗和远程医疗成为可能,其隐私保护是十分重要的研究内容。针对无线体域网中加密数据的检索问题,提出使用可多关键词搜索的公钥加密算法,并通过让云服务商参与部分解密减轻移动设备的计算压力。用户可以在不泄露隐私的情况下对云端存储的加密数据进行搜索,且该方案适用于体域网设备运算能力不足的场景。从正确性、安全性和计算效率对方案进行分析。
The combination of wireless body area network（WBAN） and cloud computing makes digital health and remote treatment possible. Privacy protection is a major concern. Proposes to use a public key encryption with conjunctive keyword search scheme, which reduces the computational overhead of WBAN devices by enabling service provider to participate in partial decipherment. This scheme protects user data privacy during the search process, and it is suitable for the WBAN device. Analyzes the scheme in correctness, security and efficiency.
