This model gives a formal definition and proof of trust state, trust root and trust measurement and chain of trust by the concept of Smith’s entity dependence and the assumption that the authenticity can measure the entity’s conduct with accuracy. Webmisbehavior cannot be detected (such as by measurement) by attestation or observation”. The TCG Roots of Trust Specification (“this specification”) is intended to supplement the TCG Glossary definition of a Root of Trust by further defining and refining the properties of a RoT, which is a component of trustworthy computing.

WebThe problem with the static root of trust is that, in gen-eral, it does not offer any guarantees about the current state of a device, since adversarial exploits can occur post-boot. Even worse, a static root of trust (e.g., TPM v1.1 or Secure Boot) is unsuitable for detecting a powerful attack class based on Return-Oriented Programming (ROP) [39].
