\label{appendix:protocol_list}

The following table lists the protocols available in 1993 for performing authentication in a distributed system. The bugs and redundancies information is also based on the knowledge people had at that time. It has been extracted from \citetitle{Liebl1993}\cite{Liebl1993}.

The types column correspond to the encryption type: it can be based on a public key (PK), a secret key (SK) or on a one-way function (OF).
