CS-E4340 - Cryptography D, Lecture, 2.9.2024-28.11.2024

Guest access
Please note! Course description is confirmed for two academic years, which means that in general, e.g. Learning outcomes, assessment methods and key content stays unchanged. However, via course syllabus, it is possible to specify or change the course execution in each realization of the course, such as how the contact sessions are organized, assessment methods weighted or materials used.

LEARNING OUTCOMES

Having completed the course, you understand the security that commonly used cryptographic primitives provide as well as their limits. You can read and understand security definitions of cryptographic building blocks and are able to judge whether a cryptographic building block is suitable for use in a particular application, and you can assess security models for applications critically. You can construct reductions between cryptographic primitives and recognize whether small modifications to a cryptographic primitive compromise their security.

CONTENT, ASSESSMENT AND WORKLOAD

Content

  • valid for whole curriculum period:

    We introduce cryptographic security models and concepts and understand the relations between them. We then apply the learnt concepts and techniques to real-world problems. In particular, we cover:

    • Pseudorandom functions/ciphers
    • symmetric encryption
    • asymmetric encryption
    • message authentication codes
    • signature schemes
    • selected advanced cryptographic primitives (might depend on the course instance), e.g., fully homomorphic encryption, cryptographic obfuscation, indistinguishability obfuscation
    • selected applications (might depend on the course instance), e.g., secure communication, attacks on TLS, secure distributed computation

Assessment Methods and Criteria

  • valid for whole curriculum period:

    The course is pass/fail, and to pass, one is required to collect a certain amount of participation points (for the exact thresholds for each teaching period and overall course, see MyCourses page of the course instance in question).

    Participation points are primarily obtained via submitting solutions to weekly exercises (there is no exam), and it is possible to pass the course by only submitting exercises.

    In some course instances, there might be additional ways to obtain participation points. See MyCourses page of the course instance in question for details.

Workload

  • valid for whole curriculum period:

    Lectures 24 h (12 90-minutes sessions),

    Teaching in small groups 24h (12 90-minutes sessions),

    Weekly written exercises 40 h (10 assignments)
