云计算意味着将数据委托给由远程服务器上外部方管理的信息系统，在“云”中，提高了新的隐私和机密性问题。我们提出了一种用于设计云服务的通用技术，该技术允许云仅查看加密数据，同时仍允许其执行与数据相关的计算。该技术基于Web浏览器中的关键翻译和混合。
我们专注于会议管理的特定云计算应用。我们确定了EasyChair和Edas姿势等现有系统的特定安全性和隐私风险，并使用基础协议Confichair（一种基于云的新型会议管理系统）来解决它们，可提供强大的安全性和隐私保证。
在Conpichair中，作者，审稿人和会议主席通过浏览器与云进行互动，以执行上传和下载论文和评论的通常任务。与当前系统相反，在Conpichair中，云提供商无法访问论文和评论的内容以及审阅者给出的分数，而且无法将作者与论文的审稿人联系起来。
我们用称赞的协议及其属性以王朝的语言表示，并证明它确实提供了预期的属性。
Cloud computing means entrusting data to information systems that are managed by external parties on remote servers, in the "cloud", raising new privacy and confidentiality concerns. We propose a general technique for designing cloud services that allows the cloud to see only encrypted data, while still allowing it to perform data-dependent computations. The technique is based on key translations and mixes in web browsers.
We focus on the particular cloud computing application of conference management. We identify the specific security and privacy risks that existing systems like EasyChair and EDAS pose, and address them with a protocol underlying ConfiChair, a novel cloud-based conference management system that offers strong security and privacy guarantees.
In ConfiChair, authors, reviewers, and the conference chair interact through their browsers with the cloud, to perform the usual tasks of uploading and downloading papers and reviews. In contrast with current systems, in ConfiChair the cloud provider does not have access to the content of papers and reviews and the scores given by reviewers, and moreover is unable to link authors with reviewers of their paper.
We express the ConfiChair protocol and its properties in the language of ProVerif, and prove that it does provide the intended properties.
