Hardware Root of Trust
A hardware root of trust is the foundation upon which all other security in a system is built, typically implemented in hardware that cannot be modified. It provides a trusted starting point for the system's boot process, ensuring that only authorized, untampered code is executed.
Without a hardware root of trust, an attacker could replace the operating system or firmware with a malicious version to steal assets. By anchoring security in the physical silicon, it provides a level of certainty that software-only solutions cannot match.
It is essential for protecting the integrity of cryptocurrency hardware, from the initial power-on to the signing of complex derivative transactions. It is the bedrock of secure computing, ensuring that the system is what it claims to be.
