A fast growing worldwide trend is to view computation as a commodity: Instead of maintaining their own computer systems, organizations or individuals may pay specialized providers to carry out the desired computation for them. This trend (often called "Cloud Computing") carries with it great promise in terms of overall computing efficiency, power consumption, and financial flexibility. However, it also opens the door to much more acute security threats than those we have encountered so far: Without additional protection, the client must completely trust the provider to perform the computation correctly, and at the same time keep the secrecy of the clients' most sensitive private data. Allowing the client to benefit from this service without putting such an unreasonable amount of trust in the provider turns out to be an extremely complex and delicate task. In particular, traditional cryptographic techniques and concepts are of no help here. Indeed, the cryptographic community is recently abuzz with a set of new techniques that are aimed at dealing with such adversarial scenarios. These include exciting new techniques for: - Computation on encrypted data (often called "fully homomorphic encryption")- Verifiable Delegated Computation- Program Obfuscation- Leakage-Resilient Cryptography- Circular Encryption- Searchable and Conditionally Decryptable EncryptionThe workshop will bring together researchers that work on different aspects of this problem, allowing for exchange of ideas and coming up with new research directions.

一个快速增长的全球趋势是将计算视为一种商品：组织或个人不必维护他们自己的计算机系统，而是向专门的提供商付费，让他们为他们执行所需的计算。这种趋势（通常称为“云计算”）在整体计算效率、功耗和财务灵活性方面带来了巨大的希望。然而，它也为我们迄今为止遇到的更严重的安全威胁打开了大门：如果没有额外的保护，客户端必须完全信任提供者正确执行计算，同时保持客户端最敏感的私有数据的机密性。要让客户从这项服务中获益，而又不对提供者给予如此不合理的信任，这是一项极其复杂和微妙的任务。特别是，传统的加密技术和概念在这里没有任何帮助。事实上，密码学社区最近正在讨论一套旨在处理这种对抗性场景的新技术。其中包括令人兴奋的新技术：-加密数据的计算（通常称为“完全同态加密”）-可验证委托计算-程序混淆-防泄漏加密-循环加密-可搜索和有条件解密加密研讨会将汇集研究该问题不同方面的研究人员，允许交换思想并提出新的研究方向。
