CERTICOM SUITE B POWER BUNDLE FOR NCIPHER HSMS TO DELIVER COMPLETE HARDWARE AND SOFTWARE SUPPORT FOR ELLIPTIC CURVE CRYPTOGRAPHY

Strength of elliptic curve cryptography meets government and commercial security requirements

MISSISSAUGA, ON (Apr 10, 2007)-Certicom Corp. (TSX: CIC) today announced a partnership with nCipher (LSE: NCH) to provide Certicom's Suite B Power Bundle products for nCipher hardware security modules (HSMs). This will allow nCipher and Certicom customers to quickly comply with the U.S. government's Suite B specifications. The need for stronger security is driving the demand for elliptic curve cryptography (ECC), which is recommended by the U.S. government and is also being adopted by industry to protect valuable information.

ECC is a computationally efficient form of cryptography - an essential building block in security applications - that offers equivalent security to other competing technologies but with much smaller key sizes. This efficiency results in faster computations, lower power consumption, as well as memory and bandwidth savings, thereby making it ideal for today's servers and enterprise applications. Because of this efficiency, organizations can meet growing security requirements, and reduce the number of servers required to manage the cryptographic keys. For example, depending on the hardware platform used, ECC can provide better than a 10:1 performance advantage over RSA and reduces the number of servers required by 7.5:1.

"By offering an ECC-enabled HSM with Certicom's Suite B Power Bundle software tools customers can easily adopt best practice and use hardware to protect their ECC applications as well as having access to the most advanced key management tools available," said Dr Nicko van Someren, chief technology officer at nCipher. "The partnership with Certicom ensures that our customers will have the most efficient and secure implementation of ECC available and be compliant with the latest government standards."

ECC is used in a growing number of sectors ranging from consumer electronics, wireless devices and semiconductors to government and financial services. In 2005, The National Security Agency's (NSA) recommended ECC as the public-key cryptosystem to protect classified and unclassified government communications. These recommendations, known as Suite B, are part of an initiative to upgrade the security infrastructure of the government's 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 Crotty, president and CEO of Certicom. "The nCipher partnership provides our government and enterprise customers with a range of deployment options allowing them to develop end-to-end ECC solutions with the highest performance implementations available and hardware protection from the most trusted name in the market."

Under the agreement, nCipher will provide the first high-speed ECC-enabled HSMs on the market and Certicom will provide Suite B software tools for developing complete ECC applications.
