TWC: Small: Techniques and Tools for General-Purpose Secure Computing and Outsourcing

受保护数据安全计算技术的快速进步为开发保护数据隐私的通用安全计算工具提供了主要动力，而不是专门任务的计算。最近出现的云计算和保护外包计算中使用的敏感数据隐私的需要是这项工作的另一个主要动机。考虑到这一点，这个项目的目标是开发一种适合于保护隐私地执行用户程序指定的任何功能的编译器。我们的编译器将用C编程语言的扩展编写的程序转换成其安全的分布式C实现，后者可以连续编译成可由本机编译器执行的二进制文件。该项目的目标是保留编程语言的所有特点，并利用若干优化技术有效地执行用户程序。安全分布式计算是利用秘密共享数据上的安全多方技术实现的，适用于安全协同计算和安全计算外包，即使在攻击者在场的情况下，这些技术也将允许更安全的云计算。其他更广泛的影响包括向女中学女生伸出援手，以提高对计算机科学的兴趣，为研究生提供一个关于云中安全计算的暑期学校项目，以及让附近一所以非裔美国人为主的大学的学生参与该研究项目。

The rapid advancement of techniques for secure computation on protected data offers a major incentive for development of tools for general-purpose secure computation that protects data privacy, as opposed to computation of specialized tasks. The recent emergence of cloud computing and the need to protect privacy of sensitive data used in outsourced computation serves as another major motivation for this work. With this in mind, this project targets at developing a compiler suitable for privacy-preserving execution of any functionality specified by a user program. Our compiler transforms a program written in an extension of the C programming language, where data to be protected are marked as private, into its secure distributed implementation in C, which can be consecutively compiled into a binary executable by a native compiler. The goal of the project is to preserve all features of the programming language and enable efficient implementation of user programs using a number of optimization techniques. The secure distributed computation is implemented using secure multi-party techniques on secret-shared data and is suitable for secure collaborative computation and secure computation outsourcing.These techniques will allow for more secure cloud computing, even in the presence of attackers. Other broader impacts include outreach to female middle school girls to increase interest in computer science, a summer school program for graduate students on secure computation in the cloud, and involving students from a nearby predominantly African-American university in the research program.
