  Countermeasures to Secure Next Generation Content

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

Business Wire

SAN FRANCISCO & 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.
