Trusted Platform Module (TPM) certificates
Introduction
STMicroelectronics embeds EK certificates (TCG Endorsement Key Credential) in its Trusted Platform
Module (TPM) products.
STMicroelectronics operates its own Certificate Authority (CA) which was certified by GlobalSign®.
Several intermediate certificate authorities may be created in order to discriminate different application
major revisions or product technology. The following table defines the current link between intermediate
CAs and product sales types.
