Abstract


We describe the implementation of a challenge-response protocol suitable for Web servers and Web browsers without HTTP digest authentication. Simple primitives are used (pseudorandom numbers, hash functions), which allow for easy implementation in Web servers. Our implementation allows Web developers to keep their own authentication information databases.
