VeriSign to endorse Infineon's PC security system

German chipmaker Infineon Technologies AG is working with VeriSign Inc. on extending the security of transactions made with personal computers.

VeriSign (Mountain View, Calif.) is set to certify Infineon's Trusted Platform Module (TPM) Certification Authority with its own Trusted Computing Root Certification Authority. This will enable the creation of VeriSign secure digital certifications on computer systems that include Infineon's TPM hardware.

Infineon's TPM offering includes an integrated circuit, a suite of embedded security and TPM system management software, as well as application software for file and folder encryption protected with hardware-based key generation and storage. PC manufacturers can use Infineon's TPM to build a security subsystem to be used for data authenticity, integrity and confidentiality.

The Trusted Computing Group, with more than 100 member companies, is a not-for-profit organization formed to develop, define, and promote open standards for hardware-enabled trusted computing. It has mandated that an Endorsement Key (EK) certificate is the only acceptable way for a TPM to prove its legitimacy and by linking with Verisign Infineon can gain that certification.

The implication for Infineon is that during chip manufacturing it is required to digitally sign an EK to confirm the authenticity and integrity of their TPM. VeriSign will then cross-sign the Infineon TPM Certification Authority with its own Trusted Computing Root Certification Authority. Additionally, Infineon said it had agreed to embed the VeriSign Class 3 Primary CA certificate into its TPM 1.2. This would provide a "trust anchor" for secure authentication services and encryption for networking applications, Infineon said.

"Through our work with Infineon, which will see VeriSign certificates embedded in the very heart of a computing environment, we can maximize the legitimacy of operating platforms," said Nicolas Popp, vice president of authentication services at VeriSign, in a statement issued by Infineon.
