Global semiconductors specialist, ST Microelectronics presents a breakthrough 32-bit Trusted Platform Module (TPM) system-on-chip that supports next-generation TCG standards for attack-resistant trusted computer hardware.  

ST Microelectronics serves customers across the spectrum of electronics applications and is a provider of Trusted Platform Modules (TPMs) to major PC OEMs.  

The new industry-leading high performance TPM enables significantly stronger security and trust for activities including e-commerce and cloud computing services.  

As part of the Trusted Computing ecosystem, the TPM is a highly secure processor mounted on the computer motherboard to protect against threats such as software attacks or theft and tampering.  

The processors safeguard sensitive data such as keys, passwords and digital certificates, and provide trustworthy reports of system integrity.  

According to the Trusted Computing Group (TCG), the industry alliance promoting Trusted Computing technology, almost all enterprise PCs, servers and various embedded systems now have a TPM inside.  

ST’s new ST33TPM12LPC increases the strength of this hardware-based security by featuring a 32-bit secure processor, which allows the device to handle advanced cryptography algorithms and support the next-generation TPM 2.0 standard.  

The ST33TPM12LPC will not only achieve functional certification but also Common Criteria security certifications based on the TPM 1.2 latest Protection Profile at EAL4+ level, thus fully complying with TPM Certification Program defined by the TCG.  

In addition, ST will be proposing derived versions with other communication interfaces such as I²C and SPI to enable a range of devices besides desktops, notebooks, servers and network equipment to perform as trusted hardware. These include printers, copiers, mobile phones, tablets, home gateways, appliances, smart meters, industrial controls and automotive electronics.  

The ST33TPM12LPC demonstrates ST’s leading position in advanced process technology and security expertise.  

According to Marie-France Florentin, General Manager, Secure Microcontrollers Division at STMicroelectronics, ST is clearly committed to bringing the highly powerful and compliant Trusted Platform Module not only to the PC industry but also to a virtually unlimited number of connected platforms.  

The NIST (National Institute of Standards and Technology) promotes best practice in using the SHA-256 (Secure Hashing Algorithm version 2, 256Bit) algorithm. However, to date, the adoption in commercial markets has been much slower than originally anticipated.  

Steve Roylance, Business Development Director for GlobalSign Ltd, the certificate authority chosen by ST to certify the Endorsement Key within the TPM explains that the decision to use this algorithm within the TPM Root Certificate supports the longer term needs of tomorrow’s trustworthy computing environments and offers real value to users today in being able to meet the NIST requirements and accelerate the replacement of ageing SHA1 implementations.  

Key features of ST33TPM12LPC TPM:  

  • ARM SC300 32-bit secure processor supports SHA1 and SHA2 hash algorithms as well as AES
  • Ready for next generation TPM 2.0
  • Embedded EK certificate root certified by independent Certification Authority (GlobalSign)
  • Embedded 90nm non-volatile memory
  • Low Pin-Count (LPC) interface
