MISSISSAUGA, Ontario--August 25, 2004--Certicom Corp. (TSX: CIC), the authority for strong, efficient cryptography, today announced it has licensed Security Builder Crypto 4.0, its cross-platform cryptographic toolkit, to Avanza Technologies to build Elliptic Curve Cryptography (ECC) into its secure identity management product, It'sM*iMail. Avanza's product generates an email address that looks and acts like a standard email address but is encrypted with security features that dictate user identification and privileges. Avanza needed the strength of ECC to provide authentication and key exchange, and the small key size to make it all fit.

It'sM*iMail fights spam and viruses by creating a non-transferable email address that prevents others from using an email address without the owner's authority. The Avanza framework gives the email creator control over who can read the message, who can respond to it and how long the address remains valid.

For Avanza, Security Builder Crypto and its optimized ECC implementations was the obvious choice for its cryptography. First, Avanza needed a cyptosystem small enough to fit into an email address. Second, the ECC implementation had to be flexible enough to work on a number of different platforms, including Pocket PC, Linux and Microsoft Win32. Third, Avanza's customer-data protection technology required a cryptographic framework robust and efficient enough to process hundreds of thousands of key pairs in conjunction with a real-time customer database to prevent theft of customer information. Finally, Avanza needed the confidence that the public-key scheme used would remain viable for the life of a potential email address -- potentially for many years.

"The email address would be unwieldy if we used any other public-key technology," said Philippe Richard, VP-Technology at Avanza, when asked why he chose ECC. "With ECC we get small key sizes which means we can express a crypto strength stronger than those used by even the most security-conscious Internet transaction sites. We chose Certicom because they had the right technology, the right expertise and the right patents."

Certicom is a pioneer in researching and developing ECC, which provides the highest strength-per-bit of any known public-key today. In 1997, the company developed the industry's first toolkit to include ECC. Security Builder Crypto is optimized for size and performance on over 30 platforms and includes strong, efficient ECC implementations. Last year, the National Security Agency (NSA) purchased extensive licensing rights to Certicom's ECC-based intellectual property, validating ECC as a strong public-key technology and spurring adoption by other companies.

"Avanza's secure identity product is another example of an application where the need for a small key size sets ECC above other public-key cryptosystems. ECC's efficient size makes it ideal for resource-constrained environments or for applications where speed is important," said Ian McKinnon, president and CEO at Certicom. "Avanza's solution offers a powerful value proposition: it protects users from unwanted email while being easy to use and adaptable across a number of platforms."
