LOS GATOS, Calif., October 10, 2001 - Network security and flow classification market leader Hifn™ (NASDAQ: HIFN) today announced that it has licensed Elliptic Curve Cryptography (ECC) technology from Certicom Corporation (NASDAQ: CERT; TSE: CIC), a leading provider of mobile e-business security. 

ECC is a public key cryptography technology commonly applied in wireless applications because its small size and high speed are well suited to low-end CPUs and mobile appliances. Hifn's industry leading, high-performance security ICs utilize unique intelligent packet processing technology and efficient encryption acceleration hardware cores for algorithms such as DES (Data Encryption Standard) and AES (Advanced Encryption Standard). Hifn will include support for ECC encryption in future offerings targeted at wireless applications. 

"We licensed Certicom's ECC technology because it is fast, secure and well proven," says Douglas L. Whiting, Ph.D., Hifn chairman and chief scientist. "Hifn's goal is to deliver to our wireless customers products that match the highest standards of security and performance in the industry." 

Hifn security processors are used by most networking equipment manufacturers to speed-up the encrypted traffic in VPNs (Virtual Private Networks) and e-commerce applications. 

"Certicom continues to provide market leaders with the best technology for wireless applications and to have Hifn opt for our technology is yet another great endorsement," says Prakash Panjwani, Certicom's senior vice president, business development. "Hifn leads the market with products that are recognized for their performance and innovation. We believe that their application of ECC continues that fine tradition."
