STMicroelectronics N.V. (ST) has introduced what it claims as the industry's highest performing Trusted Platform Module (TPM). According to the company, the ST33TPM12LPC delivers stronger security and trust for activities such as e-commerce and cloud-computing applications.

As part of the Trusted Computing ecosystem, the TPM is a highly secure processor mounted on the computer motherboard to protect against threats including software attacks or theft and tampering, ST noted. It guards sensitive data such as keys, passwords and digital certificates, and provides trustworthy reports of system integrity, added the company. 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.

ST33TPM12LPC boasts stronger security for cloud computing services.

ST's TPM SoC increases the strength of this hardware-based security as the first TPM to feature a 32bit secure processor, surpassing existing standalone implementations, described the company. This allows the device to handle advanced cryptography algorithms and be ready to 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, 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 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. "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 aging SHA1 implementations," noted Steve Roylance, business development director for GlobalSign, the certificate authority chosen by ST to certify the Endorsement Key within the TPM.

The ST33TPM12LPC supports an embedded 90nm non-volatile memory and has a low pin-count (LPC) interface. Samples of the ST33TPM12LPC are available in the TCG-recommended TSSOP28 4.4mm surface-mount package or a leadless QFN32 5 x 5mm lead-free Ecopack option. The ST33TPM12LPC will be in volume production in 1Q12.
