Description:
Establishing Electronic Trust is becoming a more important part of the digital landscape than ever before. This presentation aims to do two things: One is to use allegory and a story like approach to explain what PKI is without the math. The other seeks to paint a picture of the impact to doing business and where the road looks to be going. Part One: What is PKI in practical terms. It may seem commonplace in the industry by now, but believe you me, there are plenty who don't know a Relying Party from a hole in the ground. We'll cover some of the common terms above and beyond Digital Certificates, how they interact, and how things are managed. An attempt will be made to inject some humor as gravy to what is seen as an otherwise dry topic. This isn't to say this that finger puppets will be used, but for the people want to learn, demystifying information in plain English should be a welcome change. An explanation of the trusted roles involved in deploying certificates, the governance of the system, and the management and distribution of keys will be offered afterwards. Part Two: A few real world examples of how to apply these concepts will then be offered, having established a basic understanding of how the pieces of the jigsaw fit together. Once these topics are briefly covered, it will be time to suggest where things are going based on key events taking place in this ever active and growing industry of Identity Management. Included will be some observed happenings regarding the National Strategy for Trusted Identities in Cyberspace (NSTIC) and the much sought after on-the-fly provisioning methods.
