#OPTIGA TPM

Infineon Technologies AG has announced that it is taking security to the next level with the new OPTIGA TPM (Trusted Platform Module) SLB 9672, a future-proof security solution with post-quantum cryptography (PQC) protected firmware update mechanism using XMSS signatures. The mechanism brought by the OPTIGA TPM with PQC can counteract the threat of firmware corruption by attackers with access to quantum computers and increases the long-term survivability of the device by enabling a quantum-resistant firmware upgrade path. The standardized, 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. In addition, the OPTIGA TPM family is the industry’s first TPM to offer a firmware update mechanism with a 256-bits key length, along with an additional check based on PQC. With this strong and trusted update mechanism, the OPTIGA TPM SLB 9672 can still be updated if the standard algorithms are no longer trusted. 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.
