The U. S. Naval Research Laboratorys OPIE One-time Passwords In Everything Software Distribution is an enhancement of Bellcores SKey TradeMark 1.0 package. OPIE improves on SKey in several areas, including FTP service with one-time passwords, and a stronger algorithm for generating one-time passwords. OPIE diverges from SKey in select design decisions and in the behavior of certain programs. While not a total security solution, OPIE can be an important part of one. OPIE and its evolutionary predecessors have been used for over a year in parts of NRL. Its use has taught the authors lessons on implementation, usability, deployment, and future directions for improvement.
