Abstract

The SSH protocol provides a secure way of accessing remote systems. Besides traditional password-based authentication mechanisms, it currently only includes public-key authentication as a cryptographic method. This paper introduces an additional method based on a zero-knowledge proof of knowledge and the necessary additions to the SSH protocol. Additionally, we present a proof-of-concept implementation of our zero-knowledge scheme for OpenSSH, an open source SSH implementation.
