社交传感云安全研究进展

Research Progress of Social Sensor Cloud Security

社交传感云是由社交网络、无线传感网络与云计算结合产生的一种新型传感云系统,将虚拟社交网络信息世界与现实的物理世界融合在一起,不断为社交用户提供新的服务和应用。社交传感云(Social Sensor Cloud)不仅具备了无线传感网络在收集外界信息方面强大的社交感知能力,还利用云计算技术打破了传统传感器网络在数据处理和存储方面的局限性。但是,由于社交传感器被移动地部署在不可信的社交云环境中,导致现有的社交传感云服务面临许多严重的安全问题,如社交传感器共享数据时容易遭受恶意攻击;不同服务商与用户之间的信誉问题,导致社交传感数据泄露、服务完整性问题等,严重阻碍了社交传感云服务的进一步发展。文中针对目前已有的研究,介绍了社交传感云的产生背景、体系框架、应用领域以及系统新特性,对社交数据安全、社交传感网络安全、社交传感云服务安全的研究现状进行介绍,并分析对比了典型的安全技术方案。此外,文中还讨论了该领域面临的挑战,并对未来的研究方向进行了展望。

Social sensor clou d is a new type of sensor cloud system generated by social networks,wireless sensor networks and cloud computing,combines the virtual social networks world with the physical world,and provides new services and applications for social users continuously.It collects external information with the powerful social sensing ability of wireless sensor networks,and solves the limitations of traditional sensor networks in data processing and storage by using cloud computing technology.However,social sensors deployment in untrusted social cloud environment,which causes many serious security issues for social sensor cloud services,such as,malicious attacks when social sensors are sharing data,reputation issues between different service providers and users,social sensor data privacy leaks,service integrity issues.These security issues deeply hinder the further development of social sensor cloud services.For the related research progress of social sensor cloud,this paper introduces the background,the system framework,application fields and new system characteristics of social sensor cloud,and analyzes and compares typical security technology schemes.In addition,the key scientific issues to be solved in this field are discussed,and the future research work is prospected.
