Quantum computing will have a significant impact on cyber security, posing a threat to ensuring the confidentiality of encrypted data and the integrity of digital signatures. To address these challenges, Infineon Technologies has introduced the new OPTIGA TPM (Trusted Platform Module) SLB 9672, which is designed to further enhance system security. The TPM chip uses a firmware update mechanism based on post-quantum cryptography (i.e., XMSS, a hash-based signature algorithm), which is a forward-looking security solution.

     The mechanism can resist attacks launched by hackers using quantum computers, protect firmware from damage, and its quantum-computation-resistant firmware upgrade mode can ensure the long-term availability of devices. OPTIGA TPM SLB 9672 is a standardized, no-installation, out-of-the-box solution that effectively protects PCS, servers, and networked devices from unauthorized access, verifies software status, and protects the integrity and confidentiality of static and in-transit data.

     OPTIGA TPM SLB 9672 is a new product of Infineon's OPTIGA TPM family of security chips and the industry's first TPM to use post-quantum cryptography (PQC) for firmware updates, with a key length of 256 bits. With this powerful, reliable update mechanism, OPTIGA TPM SLB 9672 allows firmware upgrades even when standard algorithms can no longer be trusted. In addition, the TPM chip provides fault protection to eliminate firmware damage and improve computing performance. For example, the built-in fault protection function can be used to successfully repair the TPM firmware according to the NIST SP 800-193 Platform Firmware Protection and Recovery Specification.

     The TPM chip also incorporates an extended non-volatile memory for storing additional certificates and encryption keys, among other things. Its security assessment and certification is conducted by an independent body in accordance with the relevant requirements of the International General Standards (CC) and the Federal Information Processing Standards (FIPS). The new TPM chip is also fully compliant with the Trusted Computing Organization's (TCG) requirements (TPM2.0 Standard Version 1.59) and certified according to the latest TPM2.0 standard.

     OPTIGA TPM SLB 9672 is a standardized trusted platform module equipped with a variety of tools (software/evaluation board) to support product design and easily integrated with host software. It is also capable of supporting the latest versions of Windows and Linux operating stably in a wide temperature range from -40°C to 105°C. Infineon promises that the OPTIGA TPM SLB 9672 will last at least 10 years. The company will provide customers with customized technical support and maintenance services through the Infineon Security Partner Network (ISPN). This commitment allows customers to continue to use TPM chips with confidence and access to Infineon's unique technical support.
