STMicroelectronics Expands STSAFE Range with New Advanced Security Modules
Expansion of the STSAFE family provides devices certified to the highest security-industry standard and with the largest on-chip memory for storing sensitive data
STMicroelectronics has introduced two state-of-the-art security modules that provide an industry-validated shield to protect computers and
smart connected devices against cyber-attacks. The new STSAFE Trusted Platform Modules (TPM) store system-authentication data such as cryptographic keys and
software measurements in inaccessible and unalterable hardware, offering an industry-standardized way to protect PCs and servers,
as well as other home and office equipment such as printers, copiers, home gateways, network routers, and switches.
This protected storage prevents attackers from interfering with the device’s integrity, stealing private data, or taking over the system
to gain unauthorized access or privileges that would put the system, data, or its network at risk.
“Robust security is central to maintaining trust in the rapidly growing number of smart connected devices that support
the way we live and work,” said Marie-France Florentin, General Manager, Secure Microcontrollers Division, STMicroelectronics.
“Our state-of-the-art security modules combine the latest trusted computing technology with value-added features that
enable superior protection for end-users’ privacy and safety.”
The Trusted Computing Group’s latest TPM 2.0 specification adds extra features over and above the earlier TPM 1.2,
including cryptographic algorithms and support for user hierarchies. The first of ST’s new STSAFE-TPM devices,
the ST33TPHF2ESPI, supports both specifications and can switch easily between the two, allowing OEMs to provide TPM 1.2 or TPM 2.0 capability
on the latest device technology. The second device is the ST33TPHF20SPI, which supports TPM 2.0 and has the largest non-volatile memory
in the market to provide up to 110Kbytes storage for sensitive data.
The STSAFE-TPM modules leverage ST’s expertise with the secure ARM® SecurCore® SC300™ processor, which has anti-tamper,
data-watching, and memory-protection features. Both devices are Common Criteria (CC) and Trusted Computing Group (TCG) certified
against the applicable TPM 1.2 and 2.0 protection profiles and US Federal Information Processing Standard (FIPS) 140-2 certifications are in progress.
The new modules come with RSA and ECC Endorsement Keys (EKs) needed to support authentication and associated key certificates are provided,
signed by the independent certification authority Globalsign Ltd to guarantee authenticity.
STSAFE is a family of authentication products offering turn-key solutions. All STSAFE products rely on highly secure MCUs that achieve top-level
Common Criteria EAL5+ certification, as certified by independent labs. The STSAFE product family is aimed at offering well-tailored solutions
to meet the increasing security challenges in Trusted Computing, Brand Protection, and the IoT.
¹ TPM1.2 and TPM2.0 are both approved as formal international standards under ISO/IEC (the International Organization for Standardization and the International Electrotechnical Commission).
² RSA and ECC: cryptographic algorithms supported by TPM 1.2 (RSA) and 2.0 (RSA and ECC) specifications
³ Endorsement Key: a cryptographically encoded key pair used to authorize transactions and identify deviations from a known equipment configuration
