Santa Clara, Calif.-based Transmeta on Tuesday
announced plans to issue a new version of its TM5800 Crusoe processor with
embedded technologies for securing sensitive data and delivering
tamper-resistant x86 storage environments.
Transmeta said its Crusoe processors (which already feature Code
Morphing software) would be slightly altered to tackle security and address
requirements for securing sensitive data and intellectual property.
Embedding these features in the main processor provides increased security
over existing multi-chip solutions, the company said.
The new security technologies include secure hidden storage of
confidential information, encryption acceleration and a processor
architecture that can be extended to support new features and industry
standards, such as the Advanced Encryption Standard (AES)
Transmeta said the new security technologies would ship in the second
half of 2003.
The company, which sells its chips to notebook computer makers like
Sony,
Toshiba and Fujitsu, said the providing of secure storage of certificates
and keys for authentication and encryption of confidential data was a
“critical challenge facing the computer industry and end users.”
Because existing software for storage security are external components,
Transmeta said they add cost and system space requirements. To address
this, Transmeta’s new security technologies would provide interfaces to the
Crusoe architecture that enable both runtime and secure storage of
certificates, keys, and eventually, other confidential information.
It said the storage facilities within the Crusoe architecture would
be invisible to the x86 space, representing a tamper-resistant environment.
The new processors would also feature a hardware acceleration engine for
commonly used symmetric key encryption algorithms such as the Data
Encryption Standard (DES), DES-X and Triple-DES. The company said hardware
support for DES, DES-X and Triple-DES would speed up security applications
such as file and disk data encryption and the Internet Protocol Security
(IPSec) algorithm commonly used in Virtual Private Networks (VPNs).
Competitors Intel and AMD
have also outlined
plans
to build security features into their chipsets.
