To address these challenges, Infineon Technologies has unveiled the OPTIGA TPM (Trusted Platform Module) SLB 9672, a future-proof security solution with a post-quantum cryptography (PQC) protected firmware update mechanism using XMSS signatures.
This mechanism counteracts the threat of firmware corruption by attackers with access to quantum computers and increases long term survivability of the device by enabling a quantum-resistant firmware upgrade path. According to Infineon, the standardised, out-of-the-box TPM provides a solid foundation for securely establishing the identity and software status of PCs, servers, and connected devices, and for protecting the integrity and confidentiality of data at rest and in transit.
According to the company, this is the first TPM to offer a firmware update mechanism with a 256-bits key length, along with an additional check based on PQC. With this mechanism, the OPTIGA TPM SLB 9672 can still be updated if the standard algorithms are no longer trusted. Its design is engineered for improved computing performance with fail-safe features that counteract the effects of corrupted firmware. For instance, built-in fail-safe features enable TPM firmware recovery in accordance with the NIST SP 800-193 Platform Firmware Resiliency Guidelines.
This TPM also provides an expanded non-volatile memory to store new features such as additional certificates and cryptographic keys. Security evaluation and certification are performed by independent bodies according to the Common Criteria and FIPS requirements. The TPM also fully complies with the Trusted Computing Group (TCG) requirements (TPM 2.0 standard version 1.59) and is certified according to the latest TPM 2.0 standard.
Featuring a standardised trust base, as well as various tools to support design activities (software/demo boards), this TPM can be easily added via with host software. It also supports the latest versions of Windows and Linux.
In addition, the chip boasts an extended temperature range of -40°C to 105°C.
Infineon is committed to the long-term availability of OPTIGA TPM SLB 9672 for a minimum of ten years and offers tailored support and maintenance through the Infineon Security Partner Network (ISPN).
