Others Problem
Spring 2000
Due May 10, 9pm
Intro
In the last lecture we looked at SSL/TLS both as
a protocol, as messages, and remaining problems.
SSH is similar, but not the same.
Problem
Research SSH and answer the following questions:
-
The format of SSH protocol messages, e.g., the arrangement
of headers and trailers..
-
The actual set of SSH messages, e.g., all the possible SSH
messages, including alerts.
-
The general operation of SSH, e.g., who is the client, who is
the server, how is a relationship maintained.
-
The certificate authority, and the format of the actual
certificates.
-
How authentication, integrity, and privacy are maintained,
what are the possible algorithms, DES, etc.
-
The differences between ssh 1 and ssh 2, was ssh 1 broken or
is ssh 2 just an enhancement.
-
The critical issues for breaking ssh, e.g., lousy certificate,
?
Anything else you want to tell me.
