Elliptic Curve Cryptography and Certicom implementations add fast and secure digital signature capability to ImageNow products

MISSISSAUGA, Ontario – (October 28, 2004)– Certicom Corp. (TSX: CIC), the authority for strong, efficient cryptography, that Perceptive Software, known for its innovative document imaging, management and workflow software, has licensed Security Builder® PKI™ software developer toolkit. For Perceptive Software, the toolkit will enable its developers to quickly and easily add digital signature functionality to its ImageNow® suite of products. Perceptive Software's customers benefit because they can now use digital signatures natively to approve documents, thereby eliminating additional steps and saving time. And, because the Perceptive Software team chose to use elliptic curve cryptography (ECC) algorithms, customers can expect the process to be fast and secure, regardless of the number of documents being signed.

Enterprise customers use Perceptive Software's solutions to electronically capture, index and store documents in one central repository, which allows users to search, route and view the documents from any business application. These capabilities create measurable efficiencies, and by enabling their customers to approve documents electronically, the approval workflow process is shortened even more.

In sourcing a solution, the Perceptive Software team had two overriding criteria. It had to be a proven technology and it had to be fast. The team ruled out open-source admitting that the associated costs were too great, especially in light of patent indemnifications and the ongoing need for code updates and maintenance. Given that many of their customers handle sensitive documents-healthcare, financial, government and human resource markets-the team wanted trusted implementations backed by cryptography experts who could provide ongoing support and code maintenance. Speed was critical because the solution would have to handle a large number of documents.

"We initiated a competitive process but were quickly focused on Certicom and its technologies around ECC, which had the speed and strength we need," said Darren Knipp, senior product manager at Perceptive Software. "Not only was the Certicom team responsive, it was backed by 20 years of experience with ECC and validation from security-sophisticated customers like the National Security Agency and Motorola."

Convinced of the merits of ECC, Perceptive Software's checklist didn't stop with the technology. They had certain expectations for the toolkits, all of which were met. Knipp describes the Certicom toolkits as extensive and flexible. Not only are all of the functions for digital signatures available, including verification, hashing, authentication and certificate and trust validation, developers are given implementation options. "We really liked the ability to get to the low-level API components," said Knipp.

"By choosing ECC, and Certicom's toolkits to implement it, the Perceptive Software team is meeting and exceeding their customers' expectations. They are providing strong security to protect sensitive documents and technology that will not impact user experience," said Ian McKinnon, president and CEO of Certicom. "As ECC adoption continues to grow, enterprises will begin to ask for it and Perceptive Software will already be ahead of the curve."
