Abstract

This paper examines a relatively new problem of how to securely identify a human through an insecure channel. It proposes a simple but powerful cryptographic scheme that fits human ability of memorizing and processing. Typical applications of the scheme are the identification verification of an user at an on-line terminal of a central computer or holder verification done by an IC card which can communicate its holder only through an equipment like an automatic vendor machine.
