Rambus Cryptography Research Division Licenses Advanced Security Technologies to Altis Semiconductor

Agreement provides protection against DPA and other side-channel attacks in mobile and other connected devices

SAN FRANCISCO and CORBEIL ESSONNES CEDEX, FRANCE, Mar. 16, 2016 – Rambus Inc. (NASDAQ:RMBS) today announced that its Cryptography Research division has signed a license agreement with Altis Semiconductor for the use of advanced security technologies. These technologies, developed by Cryptography Research, include differential power analysis (DPA) countermeasure techniques and are designed to protect against DPA and other side-channel attacks. This agreement also extends to software developed by Altis Semiconductor customers when executed on certain Altis Semiconductor manufactured chips.

"As more devices are connected, the need for superior security and protection against attacks is paramount," said Arnaud Salomon, Executive Vice President at Altis Semiconductor. "By incorporating DPA countermeasures from Cryptography Research, integral components are made available for the robust security solutions of our customers."
"DPA countermeasures are a crucial element to securing electronic systems worldwide," said Paul Kocher, president and chief scientist of the Rambus Cryptography Research division. "We're proud to work with Altis Semiconductor to ensure that anti-tamper processor solutions are equipped with the most secure solutions."

Side channel and DPA attacks are non-invasive attacks that involve monitoring the fluctuating electrical power consumption of a target device and then using advanced statistical methods to derive cryptographic keys and other secrets. Strong countermeasures to these attacks help protect tamper-resistant products used in applications such as banking, pay television, mass transit, secure ID, and wireless telecommunications.
