Infineon's TCPA-compliant security solution provides world-class
platform security in conjunction with safer application software
As internet-based communication and commerce has rapidly developed
in the past few years, the need for enhanced platform-based system
security has grown as well. With the emergence of e-commerce and an
increased reliance on the internet for all forms of communication,
businesses and consumers alike are in greater need of assurance that their
communication is trustworthy. The Infineon TPM solution provides for
authenticity validation, platform integrity metrics checking, user
confidentiality, and privacy. These attributes help to ensure that this safer
communication environment is available and address today's business and
consumer computing needs. The Trusted Computing Platform Alliance
(TCPA) was founded by Intel, Hewlett-Packard, Compaq, IBM, and Microsoft
in 1999 to address these issues and to allow for the continued growth of
internet- and computing-based communications and commerce models.
Today, the TCPA has more than 200 member companies and has developed
both hardware and software security standards to address today's need for
strong platform computing-based security and management.
The TPM-based system forms a Root of Trust for every computer and a
basis for "safer computing" among these more trusted PC clients. In the
near future, TPMs will be present in additional devices such as PDAs and
mobile phones to increase the network of trusted communication for
consumers and businesses. In addition to the ability of a TPM-based
system to authenticate remote users and systems via policy and
permission, the system can help to ensure that both users are operating
within their authorized system configuration profiles. Thus, both user
privacy and confidentiality are assured for computing-based transactions
and communication. One of the most important secured features of a
TPM-based system is its ability to support a Public Key Infrastructure (PKI).
The ability to support a public key hierachy provides the first managed
security system architecture to develop a globally assured mutual trust
network for commerce and communications on PCs, PDAs, and mobile
phones. The PKI environment helps to ensure that applications are more
secure, and extends the trusted computing model to numerous device
types that could not safely communicate in the past.
Infineon Technologies has a well-established reputation for developing
innovative and certified security solutions for numerous device types. We
have sold almost 3 billion security controllers. The TCPA and the
standards it has developed for the computing market continue to
demonstrate the need for innovation in the field of platform security.
Infineon Technologies is committed to providing certified world-class
security solutions that comply with TCPA standards in order to address
the complexities of today’s full-time network environments. Infineon has
developed the only complete end-to-end TCPA solution that includes all
required hardware, software, and management utilities to design a
complete platform security solution from one source. The Infineon TPM
Solution offers numerous security features including non-volatile memory,
multiple algorithm support, secure hashing, true random number
generation, key generation, numerous security controller sensors to
prevent physical attacks, and a secure operating system. In conjunction
with an on-going committment to providing complete security solutions,
Infineon Technologies will continue to provide complete solutions that
will guarantee the adoption of tomorrow's technologies today.

System Integration:
In order to ensure easy integration into almost every platform type PC desktop and
notebook, the Infineon TPM solution utilizes the Low Pin Count (LPC) bus interface as
defined by Intel Corporation. Utilizing the bus together with the low-cost TPM package
provides cost savings and power efficiency. Due to the available bandwidth of the LPC
bus (approximately 4 mBytes), the Infineon TPM can perform numerous sophisticated
platform security functions to enhance the safety of today's PC architecture.
In conclusion, the LPC bus offers an optimized way of easily integrating Infineon's TPM
solution into both notebook and desktop PC BIOS images for initiation of safer computing.
