Infineon has launched the world's leading TPM security chip that uses post-quantum encryption technology for firmware updates

     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 AG has introduced the new OPTIGA™ TPM (Trusted Platform Module) SLB 9672, 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 data both static and in transit.

    OPTIGA™ TPM SLB 9672 is a new addition to Infineon's OPTIGA™ TPM family of security chips and a leading TPM for firmware updates using post-quantum cryptographic technology (PQC) with a key length of 256 bits. With this powerful, reliable update mechanism, even when standard algorithms are no longer trusted, OPTIGA? TPM SLB 9672 can also be upgraded to the firmware. 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.

     PTIGA™ TPM SLB 9672 is a standardized trusted platform module equipped with a variety of tools (software/evaluation board) to support product design and easy integration 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 OPTIGA? With a service life of at least 10 years, the TPM SLB 9672 will also 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.
