摘 要:针对无线体域网(wireless body area networks,WBAN)存储资源有限的特点,在WBAN中引入云存储,将WBAN收集到的数据外包到云端,提出无证书公共审计方案保护外包数据安全。无证书公钥密码体制消除了证书管理负荷,避免了密钥托管问题。公共审计无需下载云端数据到本地,通过第三方审计员远程检查数据的完整性,保护数据隐私。在计算Diffie-Hellman问题困难性假设下,该方案被证明在随机预言模型中是安全的。模拟分析结果表明,该方案运算消耗低,更适用于云辅助WBAN中。To enhance the storage capability of wireless body area networks(WBAN),the cloud storage was integrated with WBAN.A certificateless public auditing scheme was proposed to address the security issue of the outsourced data which was collected by WBAN.The certificateless public key cryptography does not require the use of the certificate and avoids the key escrow problem.The public auditing scheme with privacy preserving did not need to download outsourced data to the local,but remotely checked the integrity of data by the third-party auditor.The proposed scheme was proved to be secure in the random oracle model under the assumption of the hardness of the Diffie-Hellman problem.Simulation results show that the proposed scheme has low computational cost and it is more suitable for cloud-assisted WBAN.
