During this week's second half of our discussion of GRC's new secure roaming authentication system, I reveal and fully describe the unique, simple, clean, and super-secure one-time password solution I designed to provide roaming authentication for GRC's employees. I also describe our own freely available software implementation of the "PPP" system, as well as several other recently created open source implementations.

Leo and I discuss questions and comments from listeners of previous episodes. We tie up loose ends, explore a wide range of topics that are too small to fill their own episode, clarify any confusion from previous installments, and present real world 'application notes' for any of the security technologies and issues we have previously discussed.

In this first of a two-part series, Leo and I discuss my recent design of a secure roaming authentication solution for GRC's employees. I begin to describe the lightweight super-secure system I designed where even an attacker with "perfect knowledge" of an employee's logon will be unable to gain access to protected resources.

Having several times addressed the value and potential of the open source, open spec., and popular OpenID system, which is rapidly gaining traction as a convenient means for providing "single sign-on" identification on the Internet, this week Leo and I examine problems and concerns, both with OpenID and those inherent in any centralized identity management solution.

Leo and I delve into some of the non-obvious problems encountered during the creation of a robust and secure eCommerce system. I explain the hurdles I faced, the things that initially tripped me up, and the solutions I found when I was creating GRC's custom eCommerce system.

Leo and I discuss two topics this week: The availability and operation of VeriSign Labs' OpenID PIP (Personal Identity Provider) beta, offering many useful features for online identity authentication; and my recent redesign of the algorithms behind GRC's popular Perfect Passwords page.

Leo and I open the Security Now mailbag to share and discuss the thoughts, comments, and observations of other Security Now listeners.
