  Cryptography Research and StarChip Sign Patent License Agreement for DPA

Business Wire

SAN FRANCISCO & MEYREUIL, France -- April 4, 2013

Cryptography Research, Inc. (CRI), a division of Rambus Inc. (NASDAQ:RMBS),
and StarChip SAS (StarChip), experts in designing and qualifying Smart Card
ICs, today announced they have signed a patent license agreement allowing the
use of Cryptography Research’s patented technology in StarChip products,
including the StarChip line of smartcard integrated circuits. Incorporating
Cryptography Research’s patented countermeasures onto their devices will help
protect StarChip’s products against differential power analysis (DPA) and
related side channel attacks. The license covers hardware and software
countermeasures developed by StarChip or its customers.

“At StarChip, we are committed to being a leading supplier in the Smart Card
industry and to delivering the highest possible level of security in our Smart
Card chips. We recently announced our innovative GAIA technology designed to
protect products against current, and future threats and to control costs by
eliminating complex and hazardous analog protection, as well as optimizing the
size of our Invincte crypto engine,” said Lucien Brau, CEO at StarChip. “The
DPA countermeasures licensed from Cryptography Research are a significant part
of the security solutions that we are delivering to our customers.”

“DPA countermeasures are crucial to securing smartcards, other semiconductor
products, and electronic systems from malicious attacks,” said Pankaj Rohatgi,
technical director at Cryptography Research. “StarChip joins a growing line of
chip makers who are licensing our DPA countermeasures. We are excited about
the integration of DPA countermeasures into their smartcard integrated chip

DPA is a form of attack that involves monitoring the fluctuating electrical
power consumption of a target device and then using statistical methods to
derive cryptographic keys and other secrets. Strong countermeasures to DPA are
important for securing mobile devices, bank cards, pay television systems,
secure identity products, secure storage media, anti-tamper products, and
other electronic systems and components. Many of the world’s leading security
standards require that devices be protected against DPA and related attacks.

Cryptography Research has developed a portfolio of more than 60 patents
covering countermeasures to DPA attacks, with additional patent applications
pending worldwide. For additional information on DPA Countermeasures or on
