A common layer of abstraction to rule all TEE: DHTee as a common ground for SGX,SEV

What is it about?

The paper discusses a way to improve the security of critical systems, like power grids or water supplies, using a technology called TEE. However, there's a challenge: not all devices use the same type of TEE, making it hard for them to work together. To solve this, the researchers introduce a system called DHTee, which uses blockchain (similar to the technology behind cryptocurrencies like Bitcoin) to help different TEEs communicate and trust each other. This ensures that our critical systems remain safe from cyber threats while allowing different devices to work in harmony.

Why is it important?

This work is crucial because it addresses a significant challenge in today's digital world: ensuring that different security systems can effectively communicate and trust each other. As we increasingly rely on technology to manage essential services and infrastructure, it's vital that these systems can work harmoniously and securely. Without a solution like the one proposed, our critical systems, like power grids or water supplies, could be vulnerable to cyber threats. By creating a "trust bridge" between different security technologies, this research ensures a safer and more integrated digital future for everyone.
