Mobile computing company looks to Certicom to meet customer demand for proven, standards-based security

MISSISSAUGA, Ontario – (November 16, 2005)– Certicom Corp. (TSX: CIC) today announced that Realm Systems has licensed Security Builder IPSec to build a proven, standards-based virtual private network (VPN) into its mobile enterprise platform.

The Realm Mobile Enterprise Platform offers a new medium for managing, distributing, and securing data and applications to authenticated end-users. The platform consists of a secure pocket-sized computer for employees and a router that centrally manages the devices for IT. When plugged into any computer USB port, mobile workers can safely and securely access data systems without installing software or configure settings.

Realm has embedded Certicom's Security Builder IPSec technology into the mobile computer to provide its customers with the leading VPN solution, which is backed by 20 years of experience in proven security technology. Realm also recognizes the value of elliptic curve cryptography (ECC) in IPSec and the advantage of implementing cryptography with smaller keys and on smaller processors.

"With today's mobile environment, chief security officers and IT managers are re-evaluating the technologies and companies they use to secure remote access," said Rick White, CEO of Realm Systems. "Thanks to Certicom's technology our platform can securely manage, distribute and secure data and applications to authenticated mobile workers."

For two decades, Certicom has focused on developing and providing standards-based security for resource-constrained environments. This expertise has resulted in an IPSec module that help companies like Realm build a VPN client that is one-tenth the size of desktop versions but with equivalent functionality. By using Security Builder IPSec, companies like Realm can provide strong security, including confidentiality, integrity and authentication-from handheld devices to the corporate network-and with support for industry-leading VPN gateways and the latest industry standards including Internet Key Exchange (IKE).

"The Realm system takes mobile security to the next level by establishing complete trust through a revolutionary new platform and proven, efficient security," said Ian McKinnon, president and CEO at Certicom. "Realm is helping companies to optimize the productivity of their mobile workforce while mitigating risks by using security backed by the industry expert."

Security Builder IPSec is one of the security services modules that comprises the Certicom Security Architecture, a comprehensive, modular and portable solution designed to allow developers to quickly and cost-effectively embed security across multiple families and generations of devices. Its Federal Information Processing Standards (FIPS) 140-2 Validated modules enable developers to meet stringent government security guidelines without having to undergo the time-consuming and costly testing process themselves.
