Finding your way in the wood: Signature Terminology and Security Resources

If you’ve been following this blog, you’ll know that we toss around lots of terms in each entry, along with references to standards, technologies, products and services.  Even if you haven’t read this blog before, you may have struggled trying to understand the difference between electronic and digital signatures, or what a "PKCS#11" is, or, for that matter, a trust anchor.

Well, struggle no more–today we published our latest security terms glossary, which should help to clearly define terms and keep everyone here in line with usage. (Let us know if we don’t!)   Over 140 terms are defined, along with spelled out acronyms, so you are no longer in the dark!  

What’s more, the glossary is posted on our Security Document Library site, part of the wiki area of Adobe’s web presence.   The Document Library contains links to the latest security documentation, including an omnibus guide, "Digital Signatures & Rights Management in the Acrobat Family of Products,"  which consolidates many separate documents we’ve had in the past on signatures, preferences, registry settings, encryption and the like.  In addition, there are links to many useful one page ‘keys’ on signature validation, icons, signature creation, etc.

Find the glossary here.  If we’ve missed any terms or some element of documentation, please email John Harris at jbharris(at)


News from Adobe’s Security Partner Community: VeriSign Joins the Adobe Approved Trust List

Several weeks ago, Adobe launched the Adobe Approved Trust List (AATL), our latest effort at making the use of digital signatures easier through better trust mechanisms.  VeriSign, already a Provider in our flagship trust program Certified Document Services (CDS) through its acquisition of GeoTrust, announced the inclusion of its Non-Federal SSP in the AATL, widening VeriSign’s trust foundation in Adobe Acrobat and Reader.

According to
Mike Stewart, CIO at the Kansas Secretary of State’s office:

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.  VeriSign and Adobe have made it easy to deploy and use.

Adobe is excited too!  VeriSign, along with other AATL charter Members and CDS Providers, is improving the capability for today’s agile enterprises and organizations to use digital signatures and bring cost efficiencies, integrity, and non-repudiation to more document workflows.
