New VIA PadLock SDK Extends Security Support in VIA C7®/C7®-M Processors for Windows and Linux Software Developers

Easy to use Software Development Kit assists developers in integrating support for the world’s most comprehensive security tools in the integrated VIA PadLock Security Engine

Taipei, Taiwan, 30 November 2005 – VIA Technologies, Inc, a leading innovator and developer of silicon chip technologies and PC platform solutions, today released for free download, an enhanced VIA PadLock Security Engine software development kit, which facilitates easy integration of the powerful military-grade security feature set included within the VIA C7™ processor family for Windows and Linux based security applications .

Integrated directly onto the die of VIA C7®/C7®-M processors, the VIA PadLock Security Engine builds upon previous generations and offers software developers a comprehensive set of security tools to help strengthen and accelerate the process of data protection without taxing system resources. The extended feature set includes the world’s fastest x86 AES encryption engine, a secure hash engine for SHA-1/SHA-256 processing, a Montgomery Multiplier to accelerate public key encryption such as RSA™, and dual quantum-based random number generators to provide an unshakable foundation for security.

The enhanced VIA PadLock SDK is an easy to use utility that simplifies the integration of support for the full feature set of the VIA C7 processor family based VIA PadLock Security Engine. Comprising a programming guide, source code for both Microsoft® Windows® and Linux operating system, and numerous sample programs for reference purposes, the enhanced VIA PadLock SDK also acts as a source for pieces of code that developers can directly copy into other programs. Offering full backwards compatibility, the enhanced VIA PadLock SDK, not only supports the full security feature set of the VIA C7/C7-M processors, but also the VIA Eden™ and VIA C3® processors.

“As VIA C7 and C7-M processor systems arrive on the market, we have a real opportunity to implement pervasive secure computing by enabling the power of VIA PadLock,” said Richard Brown , VP of Corporate Marketing, VIA Technologies, Inc. “When combined with the enhanced VIA PadLock SDK, both professional and novice software developers alike can simply and easily integrate the military-grade security offered by the VIA C7 processor family to combat the growing threat of cyber attacks on our PCs and notebooks.”

About the VIA C7® Processor Family

The VIA C7 processor family was designed to inspire a new breed of mobile and embedded devices, featuring a unique architecture that enables high performance with low power, cool temperature operation. As the smallest x86 PC processor on the market, the VIA C7 processor family is targeted specifically at the mainstream, thin and light, and ultra portable notebook segments, as well as consumer, corporate and industrial embedded segments.

To enhance the confidentiality, integrity, and authenticity of electronic data for mobile users on the go, the VIA C7 family has augmented the industry-leading on-die hardware cryptographic acceleration features within the VIA PadLock Security Engine, adding SHA-1 and SHA-256 hashing for secure message digests for data integrity, and a hardware based Montgomery Multiplier supporting key sizes up to 32K in length to accelerate public key cryptography, such as RSA™, to the world’s best random number generator (RNG) and AES Encryption Engine in the previous processor generation with the ‘Nehemiah’ C5P core. The VIA C7 family also provides execute protection (NX), providing protection from malicious software such as worms and viruses, and is used in Microsoft® Windows® XP with SP2. Integrating security directly onto the processor die ensures speeds and efficiency many times that available in software, yet with negligible impact on processor performance.
