Trident’s new TSC100™ family of SoCs to Include CryptoFirewall™ Technology from Cryptography Research

SAN FRANCISCO, Calif. and IBC 2011 — September 7, 2011 — Cryptography Research, Inc. (CRI), a division of Rambus Inc. (NASDAQ:RMBS), today announced that Trident Microsystems, Inc. (NASDAQ: TRID), a leading provider of set-top box (STB) and TV semiconductor solutions, has integrated CRI’s CryptoFirewall™ security technology into Trident’s new TSC100 family of STB System on Chip (SoCs). The advanced security measures provide a hardware foundation for conditional access and rights management systems in set top boxes using the Trident TSC100 family of STB SoCs.

“The advanced security protection provided in our solutions is a strategic differentiator for Trident,” said Mark Samuel, senior vice president and general manager of Trident Microsystems’ Set-top Box Business Unit. “As high-value digital content becomes more pervasive, it is critical to develop dedicated STB solutions to counter piracy in the Pay-TV markets.”

The Trident TSC100 family, unveiled at IBC 2011, is part of Trident’s new generation of high-performance set-top box system-on-a-chip (SoCs) designed for the worldwide satellite, cable and IPTV markets. Trident has integrated CRI’s CryptoFirewall security core to provide conditional access companies and operators with robust hardware-level protection against tampering and emulation. The CryptoFirewall core is an on-chip, hardware-based security block that protects cryptographic keys and computations from attack. Successfully deployed in over 100 million devices, CryptoFirewall has helped eliminate signal theft in some of the world’s highest-threat environments. The CryptoFirewall core can prevent the theft of pay TV broadcast signals, simplify compliance with content owners’ anti-piracy requirements, and streamline product development.

“Trident has developed an impressive platform of semiconductor solutions for digital televisions and set-top boxes to transform the consumer experience,” said Paul Kocher, president and chief scientist for CRI. “Implementing our CryptoFirewall security hardware into Trident chips provides a hardware foundation that conditional access and security solutions can leverage for securing content delivery.”
