Certicom conditional access system secures subscription revenue

MISSISSAUGA, Ontario – (February 5, 2007) –Certicom (TSX: CIC) today announced that WORLDSPACE® Satellite Radio (NASDAQ: WRSP), a global leader in satellite-based digital radio services, has licensed Certicom’s Conditional Access System to secure its Satellite Digital Radio (SDR) based broadcast services for the European market.

WORLDSPACE plans to roll out a European service on a sequential, country-by-country basis, beginning with Italy, which will be serviced by its current AfriStar™ satellite. An additional satellite is expected to provide increased capacity over Europe, enabling consumers to have access to approximately 50 channels per country of diversified sports, talk and commercial-free music programming at service maturity. Satellite radio requires a security solution that is strong enough to protect copyrighted material during transmission and at rest, while at the same time providing seamless activation and authorization by users.

Certicom’s Conditional Access System is currently deployed in millions of consumer and commercial electronic devices and protects hundreds of millions of dollars in subscription-based revenue. Certicom, the authority for strong, efficient cryptography, is the global leader in delivering security and conditional access solutions for the specialized needs of one-way digital satellite broadcasting systems and is ideally suited for other digital broadcast architectures such as Internet Protocol Television (IPTV) and mobile IPTV.

“At WORLDSPACE we pride ourselves on delivering unique, personalized content to our global subscribers. Through this agreement with Certicom, we are ensuring that our customers will continue to receive the highest quality programming available,” said Alexander P. Brown, Co – COO of WORLDSPACE. “Certicom has proven itself under the most demanding digital broadcasting environments and will deliver the highest level of security for our content while ensuring our customers the ease of use they expect.”

“WORLDSPACE has made a commitment to offer innovative programming to its users, enhancing their listening experience. The value of this level of investment demands a strong security solution,” said Ian McKinnon, Certicom’s president and CEO. “Satellite broadcasting environments present unique challenges where bandwidth constrained systems require optimized security that doesn’t affect performance.”

Under the terms of the agreement, WORLDSPACE will pay license royalties and an annual system maintenance and support fee.
