Microsoft, VeriSign ink security deal

The companies will work closely in order to integrate VeriSign's authentication services into Windows Server 2003, for enhanced businesses security and digital rights management.

Microsoft and VeriSign plan to announce on Tuesday that they will work together to offer secure Web services and enhanced digital rights management.

The deal builds on technology in Microsoft's Windows Server 2003 that allows access to data using digital signatures. Digital-signature technology, which uses a variant of the mathematics behind encryption, lets people digitally sign data and verify their identity online. VeriSign, which makes server software that manages such signatures on a large scale, plans to launch a service that will take advantage of the new Windows Server 2003 features.

By working together, Microsoft and VeriSign hope to make authenticated Web services easier to use and more likely to interoperate. "It is that combination that brings (companies) a lot of the benefits," said Nico Popp, vice president of Research and Advanced Products for VeriSign.

Suppliers that want to bid on a corporate contract, for example, could provide the potential client with their digitally signed proposals, which would then be authenticated through VeriSign's digital signature system. A company sending e-mail to a partner could mark the digital document with a rights-management tag indicating that it should be inaccessible a week later.

While such services are valuable, so-called public-key authentication has been adopted slowly, because installing the software and servers needed to support the technology is difficult, said Michael Stephenson, lead product manager for Microsoft's Windows Server group.

"This could be much simpler than it is today," he said. That is the primary aim of Tuesday's announcement, he added.

Mountain View, Calif.-based VeriSign will be the first company to provide an Internetwide clearinghouse of Web transactions for Microsoft's newest products. But the software giant said the deal with VeriSign is not exclusive and it will be looking for other partners to push the public-key infrastructure component that will make its digital-rights management strategy work.

However, Stephenson said, VeriSign currently is the largest player in that market. "We really view VeriSign as a leader in the marketplace for authentication services."
