San Jose, Calif. – March 22, 2010 – Verayo, a security and authentication solutions provider, announces its exclusive rights to U.S. patent number 7,681,103, titled “RELIABLE GENERATION OF A DEVICE-SPECIFIC VALUE,” granted to MIT by the U.S. Patent and Trademark Office. This fundamental patent covers, for example, reliable generation of silicon chip-unique values using Physical Unclonable Function (PUF) technology. Such chip-unique values can be used as dynamic, volatile secret keys for cryptographic operations.

“This license to the issued patents is a significant milestone for moving this technology into various commercial applications in the security and authentication industry,” said Dr. Srini Devadas, Professor of Electrical Engineering and Computer Science at MIT and CTO and co-founder at Verayo.

PUF-based key generation significantly elevates security and trust in cryptography-based solutions. Current state-of-the-art cryptography is based on keys that are typically stored on-chip. These keys are then used to authenticate and encrypt sessions for various applications such as identification, access control or financial transactions. With PUFs, such cryptographic solutions can provide a higher level of security and trust by dynamically generating chip-unique (or shared) volatile, though robust/reproducible, cryptographic keys, instead of storing and securing these keys. Additionally, a PUF-based cryptography solution can generate multiple, volatile secret root master keys even after being deployed in the field. This allows PUF-based cryptography solutions to renew root master keys in the field or support multiple vendors, features and functions.

About Verayo

Verayo was founded in Silicon Valley in 2005. The company is focused on building security and authentication solutions based on Silicon Physical Unclonable Functions (PUF) technology, which was invented and first implemented at MIT by Prof. Srini Devadas and his team. Since its founding, the Verayo team has designed, built, and tested ICs using PUFs and built-up a growing body of additional IP and substantive know-how beyond the initial IP that Verayo licensed exclusively from MIT. Verayo is funded by Khosla Ventures and has assembled an experienced Advisory Board drawn from the semiconductor and security industries. In addition to developing commercial products, the company is working on projects for various U.S. Defense Agencies.

MILPITAS, CA – March 22, 2010 – Linear Technology announces the LT3741, a synchronous step-down DC/DC converter designed to accurately (±6%) regulate output currents up to 20A. Its 6V to 36V input voltage range, constant current and constant voltage operation makes it ideal for a wide variety of applications, ranging from battery and supercap chargers and laser drivers to high current LED lighting. The LT3741 uses two external switching MOSFETs and delivers up to 20A of continuous output current over a wide voltage range of 0V to 34V. Efficiencies as high as 95% eliminate the need for external heat sinking. The LT3741’s frequency can be programmed and synchronized between 200kHz and 1MHz, allowing designers to optimize efficiency while minimizing external component size. Combined with a 4mm x 4mm QFN-20 or thermally enhanced TSSOP-20 package, the LT3741 provides a highly compact constant voltage and current solution.

The LT3741 uses an average current mode control scheme to maintain inductor current regulation over a wide output voltage range of 0V to VIN-2V. The regulated current is set by an analog voltage on the CTRL pins and an external sense resistor. The LT3741’s unique topology enables it to both source and sink current. The LT3741’s regulated output voltage and overvoltage protection are set with an external voltage divider. Additional features include an accurate external voltage reference, a programmable undervoltage lockout (ULVO) pin and thermal shutdown.

The LT3741EUF is available in a 20-pin 4mm x 4mm QFN package and the LT3741EFE is available in a thermally enhanced TSSOP-20, priced starting at $3.95 and $4.10 each, respectively in 1,000-piece quantities. Extended temperature versions, or “I” Grades, the LT3741IUF and LT3741IFE, are also available. Pricing starts at $4.65 and $4.82 each, respectively in 1,000-piece quantities. All versions are available from stock. For more information, visit www.linear.com.
