Prerequisites

Basic knowledge in cryptography might be helpful, as for example Cryptography I. Yet, this is not required.

This course is about various aspects of security in the internet.

Who can read my email?
How do I know that eBay is eBay, or amazon is amazon?
What is the public key of Angela Merkel? Where do I get it and how do I verify that it's really hers?
...

In the internet a large variety of protocols ("chatting programs") are in use to make this or that `secure'. VPN, IPsec, SSL, PKI, PGP are just a few tokens that need explanations. We will try to understand a little of that and how things are used and made available.
