Give some examples where traffic analysis could jeopardize security. Describe situations where end-to-end encryption combined with link encryption would still allow enough traffic analysis to be dangerous.
Since this is not my area of expertise, I searched Google under the key words "computer traffic analysis security" to get these possible sources:
http://en.wikipedia.org/wiki/Traffic_analysis

I hope this helps. Thanks for asking.
One big way, especially for login-style networks, is through password hacking. Read through the paragraph on Wikipedia's link posted above about security. It's NOT an easy read. Take your time and look up any difficult words. If you're really stuck on any terms, you know where we are :)
