Kein TCPA: Transmeta entwickelt Sicherheitsverfahren

Diese sei jedoch nicht mit der Trusted Computing Platform (TCP) verbunden, sondern eine eigene Entwicklung. Der neue Crusoe-Chio wird eine Arbeitseinheit für "Symmetric Encryption Algorithms" beinhalten, inklusive dem Data Encryption Standard (DES), DES-X und Triple DES. Transmeta kommentierte dies mit den Worten: "It's slow in software, but Transmeta reckons it's good in hardware." Pressemitteilung Transmeta Announces First Embedded Security Features for x86 Microprocessors Santa Clara, California; January 14, 2003...Transmeta Corporation (Nasdaq:TMTA) today announced that it has received first silicon for a Crusoe® TM5800 processor with new, proprietary technologies that enable the company’s current and future microprocessors to increase security for wireless computing, protect sensitive data, deter intellectual property theft and deliver tamper-resistant, x86 storage environments. As the demand for transmitting and storing digital data continues to increase, so does the need to secure these operations, especially when managing confidential information ranging from personal passwords and financial records to proprietary business data and national security secrets. "Today's corporate and government information technology managers are concerned about data security in computer systems and across networks," said Tim Bajarin, president, Creative Strategies. "By addressing security at the chip level, Transmeta is taking an important leadership role on this critical issue facing the marketplace and the computer industry." Transmeta’s Crusoe processors and accompanying Code Morphing™ software, with the support of third-party technologies, provide robust security features to address emerging requirements for securing sensitive data and intellectual property. Embedding these features in the main processor provides increased security over existing multi-chip solutions. “As computer users worldwide become more mobile and communicate via wireless technologies, the threat of information theft becomes a major concern to consumers, businesses and governments,” said Dr. Matthew R. Perry, president and CEO, Transmeta Corporation. “Transmeta has met this challenge by leveraging the company’s unique software and hardware processor design to enable embedded security capabilities unmatched by any other x86 processor.” Transmeta’s new security technologies are planned for customer availability in the second half of 2003. These technologies include secure hidden storage of confidential information, encryption acceleration and a flexible processor architecture that can easily be extended to support new features and industry standards, such as the Advanced Encryption Standard (AES). Secure Hidden Storage Providing secure storage of certificates and keys used for the authentication or encryption of confidential data for wired and wireless transmissions is a critical challenge facing the computer industry and end users. The storage of such information must be tamper-resistant. Current solutions, such as Smart Cards and the Trusted Computing Platform Alliance’s (TCPA) Trusted Platform Module (TPM), are external components that add cost and increase both design complexity and system space requirements. Transmeta’s new security technologies will provide interfaces to the Crusoe architecture that enable both runtime and persistent, secure storage of certificates, keys, and eventually, other confidential information. These storage facilities are within the Crusoe architecture and thus invisible to the x86 space, representing the ultimate tamper-resistant environment. Such robust capabilities are a direct benefit of Transmeta’s unique software and hardware approach to microprocessor design. Encryption Acceleration Transmeta’s Crusoe processors will 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. Triple-DES is an encryption algorithm approved by the United States National Institute of Standards and Technology (NIST) for the protection of government data, but is not commonly used to protect sensitive data in commercial applications due to its slow performance when implemented in software. Transmeta’s encryption acceleration should alleviate this bottleneck. Transmeta’s hardware support for DES, DES-X and Triple-DES is designed to accelerate security applications such as file and disk data encryption and the Internet Protocol Security (IPSec) algorithm commonly used in Virtual Private Networks (VPNs) to secure both wired and wireless data transmissions. Transmeta will provide interfaces to this hardware encryption engine via cryptographic instructions that are an extension to the x86 instruction set architecture. Named the Transmeta Security Extensions (TSX), these instructions will support key preparation and the DES, DES-X and Triple-DES ciphers. TSX instructions allow programmers to leverage Transmeta’s encryption acceleration hardware for increased performance when protecting data. Architectural Flexibility With its software driven architecture, Transmeta’s Crusoe processors are adaptable to the ever- changing security landscape. The company’s approach to implementing security features can be easily extended to support the newest encryption algorithms as they become ratified by the technology industry. The technology for providing secure data storage that is invisible to the x86 space can also be extended to hide the operations on such data and could in the future hide entire algorithms and intellectual property from the x86 world. With these new security technologies as an integral component of its energy efficient microprocessors, Transmeta continues to innovate and deliver to the market a solid foundation for securing the computing environment.
