Cryptography Research and Entropic Sign License Agreement for DPA Countermeasures to Secure Next Generation Content
|By Business Wire
|July 23, 2014 05:00 PM EDT
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
“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
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

The essence of data analysis involves setting up data pipelines that consist of several operations that are chained together – starting from data collection, data quality checks, data integration, data analysis and data visualization (including the setting up of interaction paths in that visualization). In our opinion, the challenges stem from the technology diversity at each stage of the data pipeline as well as the lack of process around the analysis.
