Silicon Root of Trust
What is Silicon Root of Trust
Silicon Root of Trust is firmware technology that integrates security directly into the hardware level of servers, making an immutable fingerprint in the silicon that provides advanced levels of protection against firmware attacks. It detects changes being introduced by cyber attackers and disables the server, so malicious code never penetrates and allows operation to quickly regain its original state.

Types of a silicon Root of Trust
A silicon-based hardware root of trust falls into two categories: fixed function and programmable. Essentially, a fixed-function root of trust is firmware controlled. In contrast, a hardware-based programmable root of trust is built around a CPU. Performing all the functions of a firmware-controlled solution, a programmable root of trust can also execute a more complex set of security functions
Open source
OpenTitan is the first open source project building a transparent, high-quality reference design and integration guidelines for silicon root of trust (RoT) chips
