Secure System Solutions for IT Security

Trusted computing is set to become the major IT issue for companies and governments as computer systems become ever more complex, and ever more vulnerable, in an increasingly open and hostile world.

The Trusted Platform Module (TPM)

The TPM is a secure microcontroller hardware component with a low pin-count (LPC) interface, plus embedded software, which sits on the PC or other platform motherboard and provides the first link in the chain of trust. The TPM validates the integrity of the platform hardware and BIOS, so it can then be used to verify boot, OS and application integrity. The latest TPM standard, TCG 1.2, as defined by the Trusted Computing Group (TCG), specifies a secure hardware component at motherboard level, which provides a trusted ‘root’ on which BIOS, OS and applications security can be built.

STMicroelectronics leads the industry in supplying TCG1.2 devices for the PC to major motherboard manufacturers. ST19WP18TPM is ST’s contribution to the computing platform based on the latest TCG specification version 1.2.

TPM solutions for PC motherboard

The ST19WP18-TPM System-on-Chip is provided with a complete suite of software including the core TCG software stack licensed from NTRU Cryptosystems Inc. and the Embassy® Security Center and Cryptographic Services Provider from Wave Systems Corp. Drivers and administration tools are also available, offering a turnkey solution for OEMs who want to offer a trusted platform to both the IT management community and end users. The ST19W family of secure MCU, to which the ST19WP18 belongs, is expected to receive EAL5+ certification.

Personal IT security and access control of corporate IT networks may be cost-effectively deployed using solutions based upon secure USB tokens. This is the case for PC-based applications such as secure login, secure email, digital signatures, secure Internet/Extranet/Intranet and remote access. The portability of a USB-based device allow users to carry their secure digital and biometric signatures wherever they go, so they can identify themselves securely on any digital appliance.

USB tokens and cards with USB smartcard ICs

With the 8bit based ST19XT34 device, ST was the first company to release a secure microprocessor with combined ISO 7816 and USB interfaces. We have now expanded our portfolio with a new set of USB products, providing embedded USB library support as well as higher performance based upon a 32-bit CPU architecture. The ST22T064-USB is the first in a new range of 32-bit secure microcontrollers provided in System-on-Chip form with embedded software libraries for fast development and deployment.
The ST22T064 implements a full-speed interface giving outstanding performance for applications demanding high-speed data transmissions. Key benefits include an on-chip clock recovery circuit, making ST ICs the most highly-integrated solutions currently available, requiring no external components. The ST22T064 is compliant with Windows XP standard CCID driver allowing easy system integration. In addition, other USB classes like mass storage can be implemented.
