Description of Working Group: 

The goal of the working group is to update and standardize the popular SSH protocol. SSH provides support for secure remote login, secure file transfer, and secure TCP/IP and X11 forwardings. It can automatically encrypt, authenticate, and compress transmitted data. The working group will attempt to assure that the SSH protocol:

·   Provides strong security against cryptanalysis and protocol attacks, 
·   Can work reasonably well without a global key management or certificate infrastructure, 
·   Can utilize existing certificate infrastructures (e.g., DNSSEC, SPKI, X.509) when available, 
·   Can be made easy to deploy and take into use, 
·   Requires minimum or no manual interaction from users, 
·   Is reasonably clean and simple to implement.

The resulting protocol will operate over TCP/IP or other reliable but insecure transport. It is intended to be implemented at the application level.
