CERTICOM SUITE B POWER BUNDLE FOR ELLIPTIC CURVE CRYPTOGRAPHY NOW SUPPORTS CAVIUM NETWORKS NITROX AND OCTEON PROCESSORS

Elliptic Curve Cryptography Fast Becoming Mandatory Requirement For US Government Applications

MISSISSAUGA, Ontario – (Nov. 1, 2007) – Certicom Corp. (TSX: CIC) today announced that Certicom’s Suite B Power Bundle will support the market-leading NITROX Security Processors and OCTEON Multi-core MIPS64 Processors from Cavium Networks (NASDAQ: CAVM), a provider of highly integrated semiconductor products that enable intelligent processing in networking, communications, storage and security applications. The joint solutions are targeted for high-security, US government applications as part of routers, switches, servers, appliances and gateways.

Suite B is the set of cryptographic algorithms recommended by the National Security Agency (NSA) to secure classified and unclassified communications. The private sector is also beginning to implement Suite B algorithms in a range of products and services.

Through this agreement, both Cavium and Certicom customers are able to quickly comply with the U.S. government’s Suite B specification by integrating Cavium Processors with Certicom’s software toolkits for Crypto, SSL, SSH and SRTP that are FIPS-validated and Suite B-enabled. The need for meeting stringent federal standards for security is driving the demand for Certicom’s NSA-approved ECC technology, which is recommended by the U.S. government and is also being adopted by industry to protect valuable information.

“Cavium’s line of scalable security and network services processors with advanced Suite B hardware acceleration, combined with Certicom’s Suite B Power Bundle software tools, allows our customers to be compliant with the latest government standards without compromising performance,” said Rajiv Khemani, vice president, marketing and sales of Cavium Networks. “The partnership with Certicom ensures that our customers will have the most efficient and secure implementation of ECC available.”

ECC is used in a growing number of sectors ranging from networking, consumer electronics, wireless devices and semiconductors to government and financial services. In 2005, the NSA recommended ECC as the public-key crypto-system to protect classified and unclassified government communications. Known as Suite B, these recommendations are part of an initiative to upgrade the security infrastructure of government communications to meet present and future security needs.

“ECC security technology meets the demanding requirements of many customers, including the U.S. government,” said Bernard W. Crotty, president and CEO of Certicom. “The Cavium partnership provides our network infrastructure customers the critical public key infrastructure needed to develop end-to-end ECC enabled network products with the highest performance implementations available.”
