Secure multi-party computation (MPC) allows several mutually untrusting parties to perform joint computations while keeping their inputs private. This project develops new techniques for constructing two-party secure computation protocols with low communication overhead. Building on the Principal Investigator's prior work for constructing special-purpose secure MPC protocols for greedy algorithms, this project develops new techniques that exploit the algorithmic structure of a function in order to develop more efficient secure computation protocols. The project develops new methods to achieve security against covert adversaries for linear algebraic tasks, graph matching algorithms, and problems from computational geometry. The investigators broadly disseminate the outcomes of the research and software libraries in order to benefit both theoreticians and practitioners. The project includes various educational and outreach activities such as organizing workshops for high-school students. The project has created a wiki for cryptographic constructions and security notions associated with these constructions.

安全多方计算 (MPC) 允许多个互不信任的各方执行联合计算，同时保持输入的私密性。该项目开发了构建低通信开销的两方安全计算协议的新技术。 该项目以首席研究员之前为贪婪算法构建专用安全 MPC 协议的工作为基础，开发了利用函数算法结构的新技术，以开发更高效的安全计算协议。该项目开发了新方法，以实现针对线性代数任务、图形匹配算法和计算几何问题的隐蔽对手的安全性。研究人员广泛传播研究成果和软件库，以使理论家和实践者受益。该项目包括各种教育和外展活动，例如为高中生组织研讨会。该项目为密码结构和与这些结构相关的安全概念创建了一个维基。
