The Security Project - Compiler and runtime systems for secure program execution
Computer systems are storehouses of personal information. As more and more personal data are stored in computer systems, and more and more computers are connected through the Internet, ensuring the confidentiality of the private data has become a critical problem. The Security project proposes a co-designed compiler and runtime system that securely protect private information in various computing environments.
