The Telnet protocol offer no form of encryption of the data stream. This section suggests a way to implement encryption using the standard Telnet option code scheme. The encryption option uses session keys exchanged during the authentication stage. It does not require the PGP authentication option to be used, any authentication type which exchanges session keys will suffice.
The encryption option presented here is based on an Internet RFC draft from April 1990 by David Borman of Cray Research, Inc. The draft has been modified to meet the security policy and goals set forth in this thesis.
