Certicom vice president awarded 2004 Distinguished Fellow for work with cryptography

MISSISSAUGA, Ontario – (November 22, 2004)– Certicom Corp. (TSX: CIC), the authority for strong, efficient cryptography, today announced that the Centre for Applied Cryptographic Research (CACR) has recognized Tony Rosati with the 2004 Distinguished Fellow. The award was presented at a ceremony at the University of Waterloo on Friday (November 19) evening. CACR is an internationally recognized center for research in applied cryptography and related areas of information security.

Since graduating from the University of Waterloo in 1985, Mr. Rosati has made significant contributions to advance the adoption of cryptography in commercial applications. In 1991, he co-founded TimeStep Corp. and together with colleagues, Tim Hember and Brett Howard, designed the first elliptic curve accelerator integrated circuit. They also developed a number of products to protect networking traffic. While at TimeStep Mr. Rosati was also instrumental in establishing the IP Security Protocol (IPSec) standard through the Internet Engineering Task Force (IETF). This standard is widely used today in virtual private networks to secure the transportation of data across insecure networks, including the Internet. In 1999, Alcatel (formerly Newbridge Networks) acquired TimeStep and continues to integrate the TimeStep technology into many core products.

Today, Mr. Rosati is vice president of intellectual property licensing at Certicom, responsible for deriving value from Certicom's extensive patent portfolio in the areas of elliptic curve cryptography and other related protocol and security patents. Mr. Rosati played a key role in last year's agreement with the National Security Agency, when the agency purchased licensing rights for 26 elliptic curve cryptography (ECC)-based patents from Certicom.

"Tony has been an active member of the cryptography community for almost twenty years: as a product designer, an entrepreneur and now as a senior executive at Certicom. His vision and commitment to advancing this technology have had a great impact on the security industry," said Scott Vanstone, executive director of CACR and founder and executive vice-president of strategic technology at Certicom. "This recognition reflects Tony's accomplishments and underscores the importance of elliptic curve cryptography in data security."
