Computational and logical foundations of privacy and security

对计算机和通信系统安全的需求从未像现在这样大。在网络环境中发生的计算量的增加使系统面临重大的安全威胁。幸运的是，在过去的三十年中，安全和密码学方面的工作已经产生了可以用于保护系统的复杂技术和工具。在许多情况下，存在稳定的安全原语，可用于更复杂的安全协议和系统。然而，这并不是故事的结尾。安全系统的日益复杂导致对建模、验证和测试的新工具的需求。特别是，系统或协议中使用的构建块的安全性并不能保证最终产品的安全性。我们正在开发有助于验证复杂系统和协议安全性的技术。

The need for security in computer and communication systems has never been greater. The increase in the amount of computation taking place in networked settings exposes systems to significant security threats. Fortunately, work in security and cryptography over the past thirty years has led to sophisticated techniques and tools which may be used in securing systems. In many cases, there are stable secure primitives which may be used in more complex security protocols and systems. However, this is not the end of the story. The increasing sophistication of security systems leads to a need for new tools for modeling, verification and testing. In particular, the security of the building blocks used in a system or protocol does not guarantee security in the end product. We are developing techniques that facilitate verification of the security of complex systems and protocols.
