Abstract

We outline an end-to-end password authentication protocol for the web designed to be stateless and as secure as possible given legacy limitations of the web browser and performance constraints of commercial web servers. Our scheme is secure against very strong but passive attackers able to observe both network traffic and the server's database state. At the same time, our scheme is simple for web servers to implement and requires no changes to modern, HTML5-compliant browsers. We assume TLS is available for initial login and no other public-key cryptographic operations, but successfully defend against cookie-stealing and cookie-forging attackers and provide strong resistance to password guessing attacks.
