Requirements

Except basic mathematics, no requirements are needed to particpate in this lecture.

Contents

We start with security objectives, Kerckhoffs's principle, and some terminology. Then, we provide a survey of the current methods available, such as Symmetric-Key Ciphers (e.g., AES) and one-time pads; cryptographic hash functions; Public-Key Ciphers (e.g., RSA, ElGamal). Later on, we will focus on interactive proof systems and Zero-Knowledge proofs. If time permits, we will also discuss Quantum Cryptography and Lattice Cryptography.

Organization

Schedule:

  • Lecture: Tuesday, 12-14, 101-00-036, Christian Schindelhauer
  • Exercises: Thursday, 12-14, 101-00-036, Christian Schindelhauer

 

We have a 2h lecture and a 2h exercise class. Participation is voluntary. The lecture will be recorded and published on ILIAS. The exercise class will not be recorded. Exercise sheets will be published on ILIAS on Thursday. Submission is voluntary. There are no points nor minimum requirements to participate in the exam.

Exam

If more than 12 students are registered for the exam, a written exam with a duration of 90 minutes will take place. Otherwise there will be oral exams. Please register online using the HisInOne-system. 

In the summer semester 2024 a written exam will take place on 03.09.2024 starting at 09:15 in 082-00-006 (cinema lecture hall). As the result of the  survey, the early exam will take place on 31.07.2024 at 10 am in 082-00-006. Please participate in the ongoing exam to signal if you want to show up (so that we have enough copies for you). The early exam will be published the day later. In both exams you may use a single sheet of paper (of unspecified size) with your hand written notes (on both sides).
