无线身体传感器网络（WBSNs）在物联网（IoT）时代变得越来越重要。现代医疗系统是WBSN技术越来越多地被用于各种基本手术的一个特殊领域。尽管wbsn的部署越来越多，但传感器设备的尺寸、功能和有限的数据处理能力等问题限制了它们在资源要求高的应用中的采用。虽然从云服务器提供计算和存储补充可以潜在地丰富WBSNs设备的功能，但数据安全性是影响云辅助服务可靠性的主要问题之一。现代医疗系统等敏感应用需要确保存储在远程云服务器上的用户医疗记录的隐私。由于在经济上不可能为每个客户端都设置私有云服务器，因此审计远程服务器上管理的数据安全性必然成为依赖公共云服务器的wbsn应用程序的一个不可或缺的需求。为此，本文提出了一种集成隐私保护的新型无证书公共审计方案。我们方案中的多用户模型支持用户组存储和共享数据，从而展示了在社区环境中部署wbsn的潜力。此外，我们的方案通过提供公共可验证性、转发安全机制和撤销非法组成员来丰富用户体验。实验评估证明了我们提出的方案在随机Oracle模型（ROM）下的安全性有效性，优于现有的云辅助WBSN模型。
Wireless Body Sensor Networks (WBSNs) are gaining importance in the era of the Internet of Things (IoT). The modern medical system is a particular area where the WBSN techniques are being increasingly adopted for various fundamental operations. Despite such increasing deployments of WBSNs, issues such as the infancy in the size, capabilities and limited data processing capacities of the sensor devices restrain their adoption in resource-demanding applications. Though providing computing and storage supplements from cloud servers can potentially enrich the capabilities of the WBSNs devices, data security is one of the prevailing issues that affects the reliability of cloud-assisted services. Sensitive applications such as modern medical systems demand assurance of the privacy of the users’ medical records stored in distant cloud servers. Since it is economically impossible to set up private cloud servers for every client, auditing data security managed in the remote servers has necessarily become an integral requirement of WBSNs’ applications relying on public cloud servers. To this end, this paper proposes a novel certificateless public auditing scheme with integrated privacy protection. The multi-user model in our scheme supports groups of users to store and share data, thus exhibiting the potential for WBSNs’ deployments within community environments. Furthermore, our scheme enriches user experiences by offering public verifiability, forward security mechanisms and revocation of illegal group members. Experimental evaluations demonstrate the security effectiveness of our proposed scheme under the Random Oracle Model (ROM) by outperforming existing cloud-assisted WBSN models.
