MISSISSAUGA, Ontario – (July 12, 2006)–Philips and Certicom today announced that Philips is licensing Certicom’s elliptic curve cryptography-based technology for a content protection scheme called DisplayPort Content Protection (DPCP). This is a copy protection scheme that protects data flowing between a personal computer and a display. DPCP could also be used in consumer electronics applications such as protection of content on TVs, projectors, DVD players and displays.

The Video Electronics Standards Association (VESA) recently released DisplayPort™, a new interface standard designed to unify the desktop and notebook PC markets to a common high-bandwidth display interface. DisplayPort allows high-definition digital audio to be available to the display device over the same cable as the digital video signal. It delivers plug-and-play with interoperability, and is cost competitive with existing digital display interconnects. DisplayPort is extensible and is expected to accelerate the adoption in PCs of digital outputs enabling higher levels of display performance.

“Philips agreed to license ECC from Certicom, confident that it is gaining access to the best cryptographic know-how and expertise,” said Michael Epstein, manager, technology and standards, Philips Intellectual Property and Standards. “Certicom’s ECC-based technology allows for efficient implementation, while maintaining excellent performance and security of our DisplayPort Content Protection system.”

DPCP relies on ECC for data integrity and authentication. ECC provides the most security per bit of any known public-key cryptography scheme. The cryptographic efficiency inherent in ECC benefits device manufacturers because it requires a fraction of the storage and processing power without compromising performance. The use of ECC dramatically improves the performance in the key infrastructure, enabling mass production of DPCP keys for manufacturing.

“Content protection is one of the most important issues facing industry and government today. The use of ECC in this new standard underscores the industry’s need for strong security,” said Dr. Scott Vanstone, Certicom founder and EVP strategic technology.

DPCP is the latest content protection scheme to adopt ECC. Its strength and efficiency make it ideal for content protection in resource-constrained environments. ECC has been selected by the National Security Agency (NSA) for Suite B cryptographic specifications to protect both classified and sensitive but unclassified government communications.

Under the terms of the agreement, Philips will pay royalties to Certicom for the use of Certicom’s ECC-based intellectual property.
