As one of the most promising emerging concepts in Information Technology, outsourced computation (also known as cloud computing) is transforming our perception of how IT is consumed and managed, yielding improved cost efficiencies and delivering flexible, on-demand scalability. Cloud computing reduces IT resources and services to commodities acquired and paid-for on-demand through a fast-growing set of infrastructure, platform, and service providers.Despite the relatively fast growth and increased adoption of clouds, our understanding of aspects related to their security, privacy, and economic value proposition -- and hence our ability to trust them -- is lacking. This project addresses this challenge by (a) extending cloud service-level agreements to govern aspects such as integrity of outsourced services, information leakage control, and fair market pricing; (b) developing mechanisms that allow providers to guarantee and users to verify that such trust-enhancing service-level agreements are being followed; and (c) exposing trustworthiness guarantees and tradeoffs to cloud customers and system integrators in ways that are both practical and usable.The research work pursued in this project is timely as it addresses the issues of cloud trustworthiness early enough to avoid having the conflicts among its various stakeholders develop unchecked -- as was the case with the Internet decades ago. Doing so has the potential of improving the utility and hardness of our cyber-infrastructure, with significant benefit to our economy and society. The project will ultimately lead to a better marketplace for computing resources, in which users are assured that the services they acquire satisfy their performance, security, and privacy expectations.

作为信息技术领域最有前途的新兴概念之一，外包计算（也称为云计算）正在改变我们对 IT 消费和管理方式的看法，提高成本效率并提供灵活的按需可扩展性。云计算将 IT 资源和服务减少为通过一组快速增长的基础设施、平台和服务提供商按需购买和付费的商品。尽管云的增长相对较快且采用率不断提高，但我们对其相关方面的了解安全、隐私和经济价值主张——以及因此我们信任它们的能力——是缺乏的。 该项目通过以下方式应对这一挑战：(a) 扩展云服务级别协议以管理外包服务的完整性、信息泄漏控制和公平市场定价等方面； (b) 制定机制，使提供商能够保证并让用户核实此类增强信任的服务水平协议得到遵守； (c) 以实用且可用的方式向云客户和系统集成商公开可信度保证和权衡。该项目进行的研究工作是及时的，因为它尽早解决了云可信度问题，避免了云可信度之间的冲突。各个利益攸关方的发展不受限制，就像几十年前互联网的情况一样。这样做有可能提高我们网络基础设施的实用性和硬度，为我们的经济和社会带来重大利益。该项目最终将打造一个更好的计算资源市场，让用户确信他们获得的服务满足他们的性能、安全和隐私期望。
