Trusted Chip For Desktops & Notebooks

National Semiconductor today introduced two SafeKeeper™ Trusted Input/Output (I/O) devices, new hardware products designed to embed security into desktop and notebook computer motherboards. These devices allow PC manufacturers to protect their customers’ computer systems from hackers and viruses. IBM is the first manufacturer to equip selected models of its desktop computers with National Semiconductor’s SafeKeeper Trusted I/O devices. National’s SafeKeeper family includes two parts, the PC8374T Desktop and PC8392T Notebook Trusted I/O devices, which are based on National’s embedded 16-bit CompactRISC® core technology. Both reside on the low-pin-count (LPC) bus, an ideal place for integration because it sits at the intersection of input devices to the PC.

National Semiconductor today introduced two SafeKeeper™ Trusted Input/Output
(I/O) devices, new hardware products designed to embed security into desktop and
notebook computer motherboards. These devices allow PC manufacturers to protect
their customers’ computer systems from hackers and viruses.

IBM is the first manufacturer to equip selected models of its desktop computers
with National Semiconductor’s SafeKeeper Trusted I/O devices. “IBM has led the
industry in developing secure, manageable systems since pioneering embedded PC
security in 1999,” said Clain Anderson, program director of wireless and
security solutions, IBM Personal Computing Division. “Security, encryption and
password management are key components of IBM ThinkVantage Technologies, which
simplify the PC user experience and reduce management costs for organizations of
all sizes. Using National Semiconductor’s Trusted I/O chip for our newly
launched desktop models helps make IBM ThinkCentre models featuring the IBM
Embedded Security Subsystem the most secure industry-standard desktop PCs you
can buy.”

Unlike other security hardware, National’s Trusted I/O devices integrate a
Trusted Platform Module (TPM), Super I/O and embedded firmware to implement
industry-standard Trusted Computing Group security functions. TPMs are
microcontrollers that securely store passwords, digital certificates and
encryption keys for PCs and other systems. These devices, which comply with
Trusted Computing Group (TCG) specifications, protect computer software, such as
BIOS, operating systems and applications, from unauthorized or malicious
attacks. IBM has used TPMs since 1999.

Why Offer Computer Security in Hardware?
In an era of increased national security concerns and weekly reports of
malicious attacks on PC systems, companies and consumers rely primarily on
software programs to protect corporate and personal information. Unfortunately,
these software-based security solutions are still vulnerable to attacks. In
contrast, National’s Trusted I/O devices integrate the TPM into the existing PC
architecture (Super I/O), storing the computer’s identity in silicon and making
it virtually impossible for outsiders to locate key information.

Hardware solutions provide a stronger foundation for a secure computing
infrastructure than stand-alone software systems. This infrastructure provides
protected storage of cryptographic or sensitive data, authenticates a host
computing device by verifying its identity to other computing devices, and
supplies metrics that provide a reliable and trusted network environment.

Key Technology Features and Benefits
National’s SafeKeeper family includes two parts, the PC8374T Desktop and
PC8392T Notebook Trusted I/O devices, which are based on National’s embedded
16-bit CompactRISC® core technology. Both reside on the low-pin-count (LPC) bus,
an ideal place for integration because it sits at the intersection of input
devices to the PC.

Since these new Trusted I/O devices are pin- and software-compatible with
National’s current Super I/O products, system engineers easily can create a
dual-system design that can accept either part. This gives manufacturers
flexibility to design “TPM-ready” systems without designing in an additional
empty socket.

Industry Standards and Partnerships
National developed its Trusted I/O devices to meet the Trusted Computing Group’s
TPM 1.1b specification. TCG developed these specifications with industry-leading
system, silicon and software providers to create standard interfaces and
interoperability between hardware and software layers. These industry standard
interfaces allow National to partner with security software developers such as
IBM and Wave Systems Corp. to offer customers multiple software solutions that
work in conjunction with National’s integrated hardware.

Pricing and Availability
National’s Desktop PC8374T Trusted I/O device is available now in a PQFP-128
package and is priced at $ 5 each in 1,000-unit volumes. The Notebook PC8392T
Trusted I/O device will be available in the fourth quarter of 2004 and will be
priced at $ 7 each in 1,000-unit volumes. All packages are available lead-free.
