CAREER: Secure and Privacy-assured Data Service Outsourcing in Cloud Computing

云计算推动了数据服务部署和交付方式的根本性转变，实现了灵活、动态的外包，同时降低了硬件和软件的资本成本承诺。然而，云计算也剥夺了客户对管理其数据的系统的直接控制，引发了对安全和隐私的担忧。本研究开发了提供安全和隐私保证的数据服务外包的方法，这种外包是可用的、可扩展的，并通过以下方式满足性能目标：(1)加密的云数据服务，包括模糊和排名关键字搜索，对大量用户和文件具有强大的隐私保证；(2)可扩展和所有者控制的云数据共享服务，具有细粒度的数据访问强制和可扩展性；(3)保护隐私的安全云存储审计，保持存储正确性的强大保证。启用安全且有隐私保障的数据服务外包是云计算部署成功的基础。该项目还开发课程，教授和监督学生。该项目的材料将作为教程、软件包和大众感兴趣的出版物在网上提供。

The economics of Cloud Computing Cloud Computing impels a fundamental shift in how data services are deployed and delivered, enabling flexible, dynamic outsourcing while reducing capital cost commitments for hardware and software. However, cloud computing also deprives customers of direct control over the systems that manage their data, raising security and privacy concerns. This research develops the means to provide secure and privacy-assured data service outsourcing that is usable, scalable, and meets performance goals, through: (1) an encrypted cloud data service, including fuzzy and ranked keyword search with strong privacy-assurance for large numbers of users and files, (2) scalable and owner-controlled cloud data sharing service with fine-grained data access enforcement and scalability, and (3) privacy-preserving secure cloud storage auditing that maintains strong guarantees of storage correctness.Enabling secure and privacy-assured data service outsourcing is fundamental to the success of cloud computing deployment. This project also develops curricula and teaches and supervises students. Materials of this project will be made available online as tutorials, software packages, and publications of general interest.
