the context of TC means (as defined by the Trusted Computing Group, TCG) that an entity always behaves in the expected manner for the intended purpose. The trust anchor, called Trusted Platform Module (TPM), offers various functions related to security.

Each TPM is bound to a certain environment and together they form a trusted platform (TP) from which the TPM cannot be removed. Through the TPM the TP gains a cryptographic engine and a protected storage. Each physical instantiation of a TPM has a unique identity by an Endorsement Key (EK) which is created at manufacture time. This key is used as a base for secure transactions as the Endorsement Key Credential (EKC) asserts that the holder of the private portion of the EK is a TPM conforming to the TCG specification. The EKC is issued as well at production time and the private part of the key pair does not leave the TPM. There are other credentials specified by the TCG which are stating the conformance of the TPM and the platform for instance the so called platform credential. Before a TPM can be used a take ownership procedure must be performed in which the usage of the TPM
