HAYWARD, Calif., November 20, 2001 - Certicom, (Nasdaq: CERT; TSE: CIC), a leading provider of mobile e-business security, today announced that its Digital Rights Management (DRM) and content protection security technology and services are being utilized to secure data transmission in some of the industry's most innovative wireless applications. Certicom has provided services and technology to leading applications providers, including the design of conditional access solutions for Honeywell, Inc. (NYSE: HON) to deliver its Flight Information Systems Broadcast (FIS-B) Program and for XM Satellite Radio (Nasdaq: XMSR) to deliver the first U.S. digital satellite radio service. 

"Innovative application developers have turned to Certicom for trusted security solutions that enable them to deliver subscription services that are content-protected in a manner transparent to their customers," said Simon Blake-Wilson, Certicom Director of Business Development and Cryptographer. "Certicom's leading security solutions are specifically tailored to the constraints of the wireless environment. The solutions developed with Honeywell and XM Satellite Radio illustrate the broad potential of wireless applications beyond wireless phones and computer devices." 

Certicom's technology, including its Security Builder® and SSL Plus™ software, provides a more efficient alternative to conventional public-key cryptographic algorithms in many mobile and wireless environments, allowing for faster processing speed, reduced bandwidth usage and decreased battery requirements. These advantages make Certicom's security technology particularly well suited to mobile devices that incorporate less powerful processors, such as handheld computing devices, Internet-enabled phones and two-way pagers. 

"XM Satellite Radio is transforming radio with the support and participation of its leading music and news programming partners including MTV, CNBC, CNN Headline News, CNET, Fox News, ABC News & Talk, USA Today, Bloomberg, and BBC World Service," said XM Vice President Derek de Bastos.
