      ROBERT HARLEY AND TEAM WIN $10,000 PRIZE IN CERTICOM'S ECC CHALLENGE

    MAJOR CHALLENGE EFFORT IN PUBLIC-KEY CRYPTOGRAPHY CONFIRMS ECC SECURITY

HAYWARD, CALIF., APRIL 17, 2000 - Dr. Scott Vanstone, Chief Cryptographer for
Certicom Corp., is pleased to announce that a team of researchers led by Robert
Harley, Damien Doligez, Daniel de Rauglaudre and Xavier Leroy of INRIA (France)
have solved Certicom's ECC2K-108 Challenge. For this achievement, Certicom is
pleased to award them a cash prize of $10,000.

The Certicom ECC Challenge was developed in November 1997 to increase the
industry's understanding and appreciation for the difficulty of the elliptic
curve discrete logarithm problem (ECDLP), which forms the basis for the security
of elliptic curve cryptography (ECC).

"We believe this response to our ECC Challenge demonstrates the ongoing
international commitment to the development and deployment of elliptic curve
cryptography," said Dr. Vanstone. "The effort of Harley's group is significant
because it provides practical confirmation of the theoretical estimates of the
security of the ECC cryptosystem."

The solution to the ECC2K-108 challenge is believed to be the largest effort
ever expended in a public-key cryptography challenge. It took four months and
involved approximately 9,500 machines and 1300 volunteers from 40 countries. The
amount of work required to solve the ECC2K-108 challenge was about 50 times that
required to solve the 512-bit RSA cryptosystem.

The method Harley's team used for solving ECC2K-108 is well known, having been
introduced independently by Certicom researchers and Harley's team in 1998.
Although the effort therefore provides no fundamental advances, it is
nonetheless an impressive computational achievement that demonstrates the
strength of distributed computer networks.

"Harley's team's accomplishment is an impressive example of the power of modern
distributed computing," said Neal Koblitz, Professor of Mathematics at the
University of Washington and co-inventor of ECC. "Their work shows the accuracy
of Certicom's estimates of the amount of time required to solve the Certicom
Challenges, and in this way reinforces our confidence in the security of ECC."

Harley's team's effort also supports Certicom's recommendation that keys of at
least 160 bit ECC encryption should be deployed in practice. Solving a 163-bit
ECC challenge is
