SAN FRANCISCO, Calif. & DELFT, The Netherlands -- December 19, 2013

Cryptography Research Inc. (CRI), a division of Rambus Inc. (NASDAQ:RMBS), and
Riscure today announced the certification of Broadcom’s set-top box silicon
under the Differential Power Analysis (DPA) countermeasure validation program.
The analysis, conducted by security evaluation firm Riscure, validates the
effectiveness of DPA countermeasures to protect quality content distribution
in set-top box products utilizing the Broadcom BCM7538 SoC.

“Implementing effective countermeasures to DPA is important to enable a secure
foundation for content distribution,” said Dan Marotta, Broadcom executive
vice president and general manager, Broadband Communications Group. “We will
continue to leverage our engineering expertise to be first to market and
industry leader in providing secure set-top box home networking technology to
our customers and partners.”

Cryptography Research licenses DPA countermeasure technologies to protect
devices against side channel attacks that can extract cryptographic keys and
other sensitive data from chips in set-top boxes and other home networking
products. The need to integrate more comprehensive security solutions in
set-top boxes has emerged as basic content protection solutions sometimes fail
to thwart today’s advanced piracy techniques. Broadcom is the first
semiconductor company to provide these new DPA countermeasures across its line
of set-top box SoCs.

The DPA countermeasure validation program is a certification program
administered by security experts at Cryptography Research, and involves
rigorous independent testing of products to evaluate resistance to side
channel attacks. The testing program's goal is to enable chip purchasers and
downstream customers to identify devices with effective security. In 2012
Riscure was accredited by Cryptography Research as an independent testing lab
to conduct evaluations for the DPA countermeasure validation program.

"Emerging requirements demand the highest levels of protection for premium
content distribution across the broad spectrum of pay TV systems," said
Benjamin Jun, chief technology officer for Cryptography Research. “This
certification demonstrates Broadcom’s dedication to implement state-of-the-art
security countermeasures in its SoCs.”

“Riscure has conducted comprehensive testing of the relevant cryptographic
functions deployed by the Broadcom BCM7538 SoC, which are used in pay TV
set-top box applications. We are pleased to confirm that these techniques are
effective in protecting against side channel attacks,” said Pascal Van Gimst,
managing director of Riscure Security Labs.

The BCM7538 is now approved to display the “DPA Lock” security logo, which
provides customers with assurance that devices contain DPA countermeasures
which are authorized and have been rigorously tested by an independent
security-testing lab.
