Adobe Approved Trust List Recognizes VeriSign(R) Federal and Non-Federal Shared Service Provider PKI Certificates to Digitally Sign Documents in Adobe Acrobat and Reader

MOUNTAIN VIEW, CA -- (Marketwire) -- 08/19/09 -- Government agencies, health care providers and others wishing to protect their PDF documents with independently authenticated digital signatures now have the option of relying on the most trusted brand on the Internet.

VeriSign, Inc. (NASDAQ: VRSN), the leading provider of Internet infrastructure for the networked world, today announced it is an anchor member of the new Adobe Approved Trust List from Adobe Systems Incorporated in addition to being a long-standing member of the Adobe Certified Document Services (CDS) program. The Adobe Approved Trust List (AATL) is a roster of independent Public Key Infrastructure (PKI) Certificate Authorities (CAs) trusted to verify digital signatures for users of the latest Adobe family of document creation and management applications. Adobe applications will now automatically recognize VeriSign's Non-Federal Shared Service Provider (SSP) CA as a trusted certificate authority and accept VeriSign's Federal SSP CA.

Today's announcement also means that VeriSign and Adobe are making it easier for federal agencies and enterprises to protect their PDF documents with digital signatures validated by the VeriSign® Federal and Non-Federal SSP PKI services. The VeriSign Non-Federal SSP PKI service facilitates trusted collaboration between federal and state governments and the public and private sector by enabling enterprises to operate at the assurance levels mandated by the federal government. The managed service, which is offered for free to VeriSign Federal and Non-Federal SSP PKI customers, simplifies the task of managing digital certificates for authentication, encryption and digital signing.

"As a VeriSign Non-Federal SSP-PKI customer, we are excited to now have the ability to use the certificates we've already issued to digitally sign Adobe documents as part of the AATL program," said Mike Stewart, CIO, Kansas Secretary of State. "VeriSign and Adobe have made it easy to deploy and use. It's another reason we trust VeriSign for our PKI services."

Digital signatures are increasingly used for PDF documents that may contain sensitive or confidential information, for example, engineering drawings, invoices, medical records, financial statements, legal agreements and project bids.
