Cryptography Research and Entropic Sign License Agreement for DPA Countermeasures to Secure Next Generation Content

Security technology fully protects set-top box SoCs from non-invasive side channel attacks

SAN FRANCISCO and SAN DIEGO – July 23, 2014 – Cryptography Research, the security division of Rambus (NASDAQ:RMBS), and Entropic(NASDAQ:ENTR), a world leader in semiconductor solutions for the connected home, today announced they have signed a patent license agreement allowing for the use of the Cryptography Research side-channel attack countermeasures in Entropic’s integrated circuits. The Cryptography Research patented technology will protect Entropic’s set-top box system-on-a-chip (SoC) products against differential power analysis (DPA) and related attacks. This agreement builds on the previous agreement between the two companies with Entropic already licensing the Cryptography Research CryptoFirewall™ tamper-resistant core for set-top boxes.

“While high value content enhances the Pay-TV experience, it also carries with it substantial risk for our OEM and Service Provider customers,” said Matt Rhodes, senior vice president, Global Marketing, Entropic. “Today’s premium programming requires strong protection systems and CRI’s DPA countermeasure technology provides an essential foundation for any Conditional Access or Digital Rights Management system.”

“The market demands for protection against non-invasive side channel attacks such as DPA have grown with the continued rise of high quality content,” said Paul Kocher, chief scientist of the Rambus Cryptography Research division. “Entropic has been a terrific partner for our CryptoFirewall technology and is once again taking a leadership role in deploying strong content protection technology in the set-top box SoC market.”

Using DPA, attackers can measure the power consumption of a set-top box chip to extract secret cryptographic keys stored within the set-top box. The discovery of secret keys undermines the security of set-top boxes within a service provider’s network and can result in the theft of valuable, high-quality content and services as well as leaving other data like personal information vulnerable. Set-top box SoCs that contain DPA countermeasures prevent the power consumption analysis through a series of techniques to ultimately protect the secret keys of a set-top box from being discovered.

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.
