STMicroelectronics has announced volume production of the ST19WP18 Trusted Platform Module (TPM), and confirmed that more than one million of the Trusted Computing Group (TCG) 1.2 devices, complete with software stack, have already been delivered in Q2 2005 to a number of major PC motherboard makers across the world. Embedded in a PC system, the module increases security by enabling validation of both the PC and its user, as well as providing secure storage for critical data and passwords.

Intel is shipping its first series of motherboards that make use of the ST19WP18 TPM security chip. The Intel desktop boards D945GNTLKR, D945GTPLKR, D945GCZLKR from its executive series line are based on the Intel 945G express chipset and are positioned to deliver the stability, manageability and security valued by corporate users in sectors where protection against identity theft, viruses and other attacks are especially important.

"ST was the first company to release an integrated TCG 1.2 solution, implementing this latest and most advanced TCG 1.2 specification," said Alain Jarre, director of the consumer & IT business unit in STMicro's smartcard ICs division.

The TCG is a broad alliance of major hardware and software companies working to create more secure computing environments through the use of hardware building blocks and cross-platform software interfaces.

The product now shipping is an off-the-shelf TCG 1.2-ready security solution intended for desktop and laptop PCs, and is backward compatible with the earlier TCG 1.1b specification already used in millions of PCs shipped by computer manufacturers. New functions include delegation, transport protection and locality. The chip includes the Core TCG Software Stack (CTSS) licensed from NTRU Cryptosystems Inc., which provides the essential core interface and security services framework for any application that relies on the TPM; and the Embassy Security Center (ESC) and Cryptographic Services Provider (CSP) from Wave Systems Corp., powerful TPM management and cryptographic support utilities for PC applications; the CSP is compliant with Microsoft's crypto-API specification.

In addition the software stack includes the BIOS and Windows drivers required by Windows 2000 and XP systems, including the Memory Absent and Memory Present BIOS drivers, the Windows Kernel-mode driver (TDD), and the Windows user-mode driver (TDDL). The ST19WP18 hardware is based on a full- featured 8bit microcomputer from the ST19W family of security-proven MCUs, which is dedicated to smart card and other secure applications, with an advanced 1088-bit cryptographic co-processor supporting Public Key Infrastructure (PKI) functions. It includes a 33MHz low pin count (LPC) interface compliant with the Intel specification, for communication with the host processor.
