Atmel Corp. claimed that its single-chip security device makes it possible for OEMs to build PCs and PDAs that comply with the security specifications of the Trusted Computing Platform Alliance. The AT97SC3201 is designed to permit high levels of security and interoperability while maintaining user convenience and privacy.

At $5 in volume, it is believed to rank among the lowest-cost hardware security mechanisms available for PCs, requiring no external tokens, readers, boards, or special keyboards.

When soldered onto a computer motherboard, the chip provides a secure vault where digital IDs can be stored, safe from viruses. The digital IDs can be used to secure communication channels.

The chip supports file encryption on a PC's hard disk and enables network servers to identify a computer that is requesting access and to verify that the BIOS running on that computer is correct and valid.

"The combination of an industry-standard specification that has been widely reviewed, third-party certification of the security level and availability of all the necessary on-board firmware simplifies the integration of security into a system," said Kerry Maletsky, Atmel's director of secure/ASIC marketing.
