Rambus Cryptography Research Division Licenses DPA Countermeasures to Thales

Advanced hardware-based security technologies protect against side channel attacks

SUNNYVALE, CA – April 14, 2015 — Rambus Inc. (NASDAQ:RMBS) today announced that its Cryptography Research division has licensed security technologies to Thales e-Security, a leader in information systems and communications security. In this agreement, Thales will integrate DPA Countermeasure technologies developed by Cryptography Research into its line of hardware security modules (HSMs) to protect against side-channel and related attacks. Specific terms of the agreement are confidential.

“Thales’ products are designed to stay ahead of the increasingly pervasive with sophisticated attacks being developed every day,” said Cindy Provin, VP Strategy & Marketing at Thales e-Security. “Protections against side-channel attacks will be an added important element in our robust solutions.”

“We are seeing threats intensify as there are increasing demands to keep keys protected to conduct secure transactions,” said Paul Kocher, chief scientist of the Rambus Cryptography Research division. “Thales is a critical player in the overall security space and this agreement shows their continued commitment to safeguarding information.”

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.
