  • The ST33GTPMASPI is a cost-effective and high-performance trusted platform module (TPM) targeting automotive and embedded systems.

    The product implements the functions defined by the Trusted Computing Group (www.trustedcomputinggroup.org) in the TCG Trusted Platform Module Library Specifications version 2.0 Level 0 Revision 138 and errata version 1.4. It is also based on the TCG PC client-specific TPM Platform specifications rev1.03. The applicable protection profile is TCG Protection Profile for PC Client Specific TPM 2.0.
    The product also supports the ability to upgrade the TPM firmware thanks to a persistent Flash memory loader application to support new standard evolutions.

    Key Features

      • Monitoring of environmental parameters (power and clock)
      • Hardware and software protection against fault injection
      • SP800-90A-compliant deterministic random bit generator (DRBG) built with an AIS-31 class PTG2-compliant true random generator (TRNG)
      • Cryptographic algorithms:
        • RSA key generation (1024 or 2048 bits)
        • RSA signature (RSASSA-PSS, RSASSA-PKCS1v1_5)
        • RSA encryption (RSAES-OAEP, RSAESPKCS1-v1_5)
        • SHA-1, SHA-2 (256 and 384 bits), SHA-3 (256 and 384 bits)
        • HMAC SHA-1, SHA-2 and SHA-3
        • AES-128,192 and 256 bits
        • TDES 192 bits
        • ECC (NIST P-256, P-384 curves): Key generation, ECDH and ECDSA, ECSchnorr
        • ECDAA (BN-256 curve)
        • Device provided with 3 EK and EK certificates (RSA2048, ECC NIST P_256 and ECC NIST P_384)
        • Device provisioned with 3 RSA key pairs to reduce the TPM provisioning time
    • Product compliance
      • Compliant with TCG test suite for TPM 2.0
      • Common Criteria certifications:
        • EAL 4+ on TCG TPM2.0 protection profile
        • EAL 5+ on hardware
      • Targets FIPS 140-2 level 2 certification (physical security level 3)
