The lecture "Introduction to Cryptography" (ItC) will be taught in a "flipped classroom" style. After registering in PAUL for our course, you are enrolled (up to 24 hours later) to our PANDA course via which ItC will be organized. Concretely, each week we will provide online lecturing material (mostly consisting of lecture recordings from a previous term and lecture notes). Based on these contents, which you have to work upon by yourself, we'll have weekly in-class discussion rounds. In these rounds we'll briefly summarize the contents, ask you some questions on the topics, and give you the opportunity to ask questions. The duration depends on your questions and discussions resulting from these. The better you prepare, the more you may benefit from these in-class events. Additionally, weekly we have mandatory as well as optional exercises and in-class tutorials (see details below and in our PANDA course).
