Infineon — OPTIGA™ TPM SLB 9672 & SLB 9673

Infineon OPTIGA™ TPM SLB 9672 and SLB 9673

Future-proof security solution

The OPTIGA™ TPM SLB 9672 FW15xx/ FW16.xx and SLB 9673 FW26.xx are the latest additions in a new generation of future-proof OPTIGA™ TPMs. The OPTIGA™ TPM serves as a robust foundation to identify and authenticate network infrastructure devices and equipment as well as protecting data integrity and confidentiality.

These standardized, ready-to-use security solutions are available with either a SPI interface (OPTIGA™ TPM SLB 9672) or an I2C interface (OPTIGA ™ TPM SLB 9673). The OPTIGA™ TPM SLB 9672 and SLB 9673 are future-proof thanks to a PQC-protected firmware update mechanism, extended memory, and stronger cryptographic algorithms.

Integrated resiliency features allow the TPM firmware to be recovered in compliance with the NIST SP 800-193 Platform Firmware Resiliency Guidelines.

• OPTIGA™ TPM SLB 9672 FW15.xx is the primary choice for Microsoft Windows environments/ecosystems and connected devices with PC architectures.
• OPTIGA™ TPM SLB 9672 FW16.xx offers enhanced security features such as AES bulk encryption, configuration of the TPM’s unique ID, and configuration of the endorsement primary seed.
• OPTIGA™ TPM SLB 9673 FW26.xx gives IoT “things” a unique identification number so they can connect to the IoT or the network. This number can be used to track IoT devices and equipment on the networks, and to validate their access rights. To avoid the risk of counterfeit, this number is protected from being be modified.

For a quick and easy way to set up future-proof TPM 2.0 for Raspberry Pi, Infineon offers the OPTIGA™ TPM SLB 9672 and OPTIGA™ TPM SLB 9673 RPI evaluation boards. Each board comes as a Raspberry Pi HAT (hardware attached on top) that conforms with the rules defined by the Raspberry Pi Foundation. This add-on makes it easier for users to connect the board to all 40-pin GPIO Raspberry Pi boards.

To enable easy evaluation and integration of the board, Infineon also provides the OPTIGA™ TPM Explorer, a GUI-based software tool that allows designers to check out OPTIGA™ TPM SLB 9672/73 features and use cases without deeper knowledge of the product. In addition, ready-to-use code examples can be downloaded from GitHub.
