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.

The following TPM certificates are included in the attached ZIP file:

 GlobalSign Trusted Computing CA

 ST TPM Root certificate

 ST Intermediate CA 01

 ST Intermediate CA 02

 Sample TPM EK certificate for ST19NP18PVMT (certified by ST Intermediate CA 01)

 Sample TPM EK certificate for ST33ZP24PVSC (certified by ST Intermediate CA 02)

STMicroelectronics CA infrastructure has been successfully audited by GlobalSign®. The details of the

infrastructure are available in the Certificate Practice Statement.
