Rambus, more famous for licensing high speed memory designs and fighting cases in court, is to buy privately-held Cryptography Research, Inc. (CRI), a leading semiconductor security R&D and licensing company. Rambus plans to acquire CRI for $342.5 million comprised of $167.5 million in cash, approximately 6.4 million shares of Rambus stock, and $50 million payable to CRI employees in cash or stock over three years. This acquisition will expand the breadth of Rambus’ memory and communications technologies available for licensing with complementary technologies from CRI that include patented innovations and solutions for content protection, network security, anti-counterfeiting and financial services.
Over five billion semiconductor products secured by CRI’s technology are made under license annually. CRI’s licensees include leading semiconductor, electronics and services companies such as Atmel, Infineon, Microsoft, NXP, Raytheon, Renesas, Samsung, STMicroelectronics, Toshiba, and Visa. CRI is led by internationally renowned cryptographer and scientist Paul Kocher, whose accomplishments include helping author the SSL 3.0 standard, discovering differential power analysis (DPA), as well as developing techniques for securing electronic systems against DPA attacks.
“Rambus will provide our team the perfect home to continue development of technology which addresses an increasingly complex range of security requirements,” said Kocher, president and chief scientist of Cryptography Research. “With many billions of connected devices conducting electronic transactions, storing important personal data, and delivering copyrighted content, the needs for security are paramount. Our passion is solving these challenging data security problems through innovative cryptographic techniques to the benefit of our licensed customers and consumers worldwide.”
Key technologies developed and licensed by CRI include DPA countermeasures. DPA attacks involve monitoring the fluctuating electrical power consumption of a target device and then using advanced statistical methods to derive cryptographic keys and other secrets. With CRI’s DPA countermeasures, electronic systems and security devices, such as smart cards, are protected from DPA attacks. Critical to electronic system security, DPA protection is now mandated for many government and commercial services.
“The addition of CRI’s world-class security technology is a pivotal step in our strategy to extend our IP leadership and aggressively drive our revenue growth,” said Harold Hughes, president and chief executive officer at Rambus. “Combined with our complementary semiconductor, and lighting and display technologies, we will create an unrivaled set of innovations and solutions critical for a broad range of electronics, with particular focus on the fast growing mobile market.”
CRI also offers anti-piracy and anti-counterfeiting solutions including CryptoFirewall technology. The CryptoFirewall core is a separate, on-chip, hardware-based security block that protects cryptographic keys and computations from attack. CryptoFirewall solutions can be used across a broad spectrum of applications including Pay TV security and counterfeit protection of printer consumables.
