Building a Better Shield for Computer Chips

Creating secure designs for computer chips is no easy task. It takes a lot of time and effort. Even small mistakes can cause big problems. To tackle this, a new system called CITADEL was created. It's like a building block set for security. You can mix and match different parts to create a strong defense. One big worry in the world of computer chips is something called supply-chain attacks. These happen when bad actors sneak harmful parts into the chip-making process. CITADEL was tested to see if it could stop these attacks. The results show that it can, and it doesn't use up too many resources. But building a security system that can handle many different threats is hard. CITADEL has some smart ways to deal with these challenges. Real-world examples show how it works and what it can do. When it comes to using CITADEL, it doesn't take up much space or power. This makes it a good choice for keeping computer chips safe.
