Global defense manufacturer uses Certicom modules to meet security requirements to protect government information

MISSISSAUGA, Ontario – (April 11, 2006)–Certicom Corp. (TSX: CIC) today announced that L-3 Communications, a manufacturer of military satellite communication terminals, has licensed Certicom technology to meet emerging National Security Agency (NSA) security requirements, including Suite B. Suite B refers to the NSA's cryptographic specifications for securing both classified and unclassified communications.

The U.S. government, through the NSA, has identified elliptic-curve cryptography- (ECC) based security mechanisms as the recommended technology for protecting government communications. ECC provides more security per bit and a longer life span than other public-key cryptography schemes. Certicom's cryptographic modules provide developers with the tools to efficiently implement ECC-based security mechanisms.

"Compliance with regulatory requirements is critical to our business. Certicom gives us a cost effective way to ensure that our products meet all of the necessary security standards required by our customers," said Rick Roane, security systems engineer with L-3 Communications. "Certicom is the authority on ECC so by working with them we are confident we are providing customers with proven, efficient implementations."

Certicom is well known as the ECC pioneer and expert, having researched and developed ECC-based security implementations for more than 20 years. The Certicom Security Architecture, a modular and portable set of security services, enables device manufacturers and other government suppliers to easily add strong, efficient cryptography into applications, and across multiple families and generations of devices.

"Through the crypto modernization program, the NSA has recommended security standards for the next few decades and has identified ECC-based algorithms as the public-key cryptography scheme of choice," said Ian McKinnon, Certicom's president and CEO. "By selecting Certicom, L-3 Communications will benefit from Certicom's vast expertise and efficient implementations of ECC-based security mechanisms."
