STMicroelectronics has introduced a personal computer security solution meeting the Trusted Computing Group (TCG) 1.2 specification.

The basis of the company's solution is the single-chip ST19WP18 Trusted Platform Module (TPM), a fully featured microcomputer from the STMicro's ST19W family of security-proven MCUs that has an advanced cryptographic co-processor supporting PKI (Public Key Infrastructure) functionalities. It includes a 33MHz Intel-compliant LPC (Low Pin Count) Interface as recommended by TCG PC Client Specific TPM Implementation Specification (TIS) for communication with the host processor.

The ST19WP18-TPM is based on an 8-bit CPU architecture with an embedded set of memories (ROM, RAM & EEPROM NVM) and security features. A 1,088-bit Modular Arithmetic Processor (MAP) is designed to speed up cryptographic calculations using Public Key Algorithms.

Backward compatible with the earlier 1.1b specification, the new solution currently includes software layers providing support for Windows 2000/XP OSs drivers, and MA (Memory.Absent) and MP (Memory.Present) BIOS drivers.

The fully compliant 1.1b embedded firmware supports features like cryptographic key generation, integrity metrics and secure storage. In addition, the device is TCG v1.2 ready and provides support for the new functions such as Delegation, Transport Protection and Locality.

Prototypes of the ST19WP18-TPM packaged in TSSOP28 will be available in the second quarter of 2004, with production planned for the second half of 2004. Pricing is $4 in quantities of 10,000-unit.

The TCG is a broad alliance of major hardware and software companies which aims to create more secure computing environments through the use of hardware building blocks and cross-platform software interfaces, without compromising functional integrity, privacy or individual rights.
