STMicroelectronics STSAFE-TPM trusted platform modules

STMicroelectronics has launched the FIPS 140-3 certified STSAFE-TPM trusted platform modules (TPMs), a range of standardised cryptographic modules that are designed to provide cryptographic asset protection to meet security and regulatory requirements for critical information systems.

The ST33KTPM2X, ST33KTPM2XSPI, ST33KTPM2XI2C, ST33KTPM2I and ST33KTPM2A are used in PCs, servers and network-connected IoT devices, as well as medical and infrastructure high-assurance equipment. The ST33KTPM2I is qualified for long lifetime industrial systems. The ST33KTPM2A, commercialised under the name STSAFE-V100-TPM, leverages an AEC-Q100 qualified hardware platform required for automotive integration.

The products support use cases like secure boot, remote/anonymous attestation and secure storage with an extended user memory of 200 kilobytes. In addition, each product supports secure firmware update to add new cryptographic algorithms like PQC and maintain state-of-the-art cryptographic asset protection.

The STSAFE-TPM devices are compliant with multiple industry security standards. These include Trusted Computing Group TPM 2.0 applicable to trusted platform modules, Common Criteria EAL4+ and now FIPS 140-3 level 1 with physical security level 3. They offer cryptographic services (ECDSA & ECDH up to 384 bits, RSA up to 4096 including key generation, AES up to 256 bits, SHA1, SHA2 and SHA3), standardised by TCG and compatible with software stacks under FIPS 140-3 certification.

ST also offers provisioning services to load device keys and certificates to reduce the total solution cost and time to market and to guarantee the security of the supply chain.
