Modules boost online security for data

Hardware-based online security is extended with the STSAFE family of trusted platform modules (TPMs) from STMicroelectronics. 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 two security modules provide an industry-validated shield to protect computers and smart connected devices against cyber-attacks.

They store system-authentication data such as cryptographic keys and software measurements in inaccessible and unalterable hardware, offering an industry-standardised way to protect PCs and servers, as well as other home and office equipment such as printers, copiers, home gateways, network routers, and switches. Protected storage prevents attackers from interfering with the device’s integrity, stealing private data, or taking over the system to gain unauthorised access or privileges that would put the system, data, or its network at risk.

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 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 modules use 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 modules come with RSA and ECC Endorsement Keys (EKs) needed to support authentication and associated key certificates are signed by the independent certification authority Globalsign to guarantee authenticity.

Both modules are available in either a TSSOP28 or QFN32 package. Both devices are in production now.
