The security kernel isdivided into two parts and trusted mechanism Is separated from security functionality. Ihe TCBmodule implements the trusted mechanism such as measurement and attestation, while the othercomponents of security kernel provide security functionality based on these mechanisms. Thisarchitecture takes full advantage of functions provided by trusted platform and clearly defines thesecurity perimeter of TCB so as to assure stlf-securily from architcetmal vision.
