Root of Trust

Definition ∞ A root of trust is a highly secure, immutable, and trusted component within a computing system that serves as the foundation for all security operations. It is typically hardware-based and responsible for verifying the integrity of other system components, ensuring that only legitimate software is executed. This foundational element cannot be modified or compromised, providing a secure starting point for the entire security chain. Establishing a robust root of trust is critical for protecting sensitive data and operations.
Context ∞ In the realm of digital assets and secure computing, the root of trust is paramount for establishing verifiable execution environments and protecting cryptographic keys. Discussions often involve hardware security modules (HSMs) and Trusted Platform Modules (TPMs) as physical implementations of this concept. News about supply chain security or advancements in confidential computing often highlights the importance of a strong root of trust.
