Prompted User Retrieval of Secret Entropy: The Passmaze Protocol

Daniel R. L. Brown

Abstract

A prompting protocol permits users to securely retrieve secrets with greater entropy than passwords. The retrieved user secrets can have enough entropy to be used to derive cryptographic keys.

Note: Minor clarifications and corrections.
