Subject: Paper: Weaning the Web off of Session Cookies

Hello,

I've just posted a new paper some of you may be interested in:
  http://www.vsecurity.com/download/papers/WeaningTheWebOffOfSessionCookies.pdf  

While it's primarily an argument for fixing HTTP authentication, it
does contain information on a few weaknesses common in browsers,
including password manager issues and user interface vulnerabilities.

Feedback is more than welcome.

Enjoy,
tim

Abstract
========
In this paper, we compare the security weaknesses and usability
limitations of both cookie-based session management and HTTP digest
authentication; demonstrating how digest authentication is clearly the
more secure system in practice.  We propose several small changes in
browser behavior and HTTP standards that will make HTTP authentication
schemes, such as digest authentication, a viable option in future
application development.
