What about private & Public Keys

[Thomas.Hluchnik at netcologne.de]

Maybe this subject has already been discussed here.

Given, an attacker succeeds to break into a large number of tornodes and gets a copy of the secret keys from all those nodes. This would increase the chance to decrypt parts of the traffic that goes through the tor network. Am I right?

So would it be of advantage for the to network to change keys from time to time, like one should do with his passwords? Lets say, each month? Would this be of negative impact to the tor net?

What is your opinion?
