-## 1. TCB Measurement
 
-The diverse application in confidential computing could be firmware or monolithic application
-in Confidential VM(CVM), micro service or macro service on Kubernetes. Although
-different type application might get the trust states measured in different Trusted
-Computing Base (TCB), the definition and structure of integrity measurement register and
-event log follows the below specifications.

-## 2. Trusted Foundation
-
-Normally Trusted Platform Module(TPM) provides root of trust for PC client platform.
-In confidential computing environment, vTPM (virtual TPM) might be provided different
-vendor or CSP, which root of trust should be hardened by vendor secure module. Some
-vendor also provided simplified solution:
