\centerline{\sc Abstract}
{\rightskip=0pt\narrower\narrower
\noindent
The design of the \TTI/ prototype Trusted Mail Agent (\TMA/) is discussed.
This agent interfaces between two entities:
a key distribution center (\KDC/) and a user agent (\UA/).
The \KDC/ manages keys for the encryption of text messages,
which two subscribers to a key distribution service (\KDS/) may exchange.
The \TMA/ is independent of any underlying message transport system.

\lp
Subscribers to the \KDC/ are known by unique identifiers,
known as IDs.
In addition to distributing keys,
the \KDC/ also offers a simple directory lookup service,
in which the ``real-world'' name of a subscriber may be mapped to an ID,
or the inverse mapping may be performed.

\lp
This document details three software components:
\underbar{first},
a prototype key distribution service,
which has been running in a TCP/IP environment since December, 1984;
\underbar{second},
a prototype trusted mail agent;
and, 
\underbar{third},
modifications to an existing \UA/,
the Rand \MH/ Message Handling system,
which permit interaction with the prototype \TMA/.
