TM8107 - Cryptographic Protocols and Their Applications


Lessons are not given in the academic year 2018/2019

Course content

The course will be given every second year, on demand, next time spring 2020.

The course will study mechanisms and properties of cryptographic protocols that establish and maintain security properties of information exchange in two-party and multiparty settings within ambient open communications networks. More complex requirements beyond basic communication secrecy and authenticity are identified in e-commerce, banking services, health informatics, digital payments and credentials, auctions, voting. The course will give models and classes of attack; computational classes, parameter and key establishment protocols; authentication protocols; commitment protocols; zero-knowledge techniques; consensus/multiparty computations; privacy-preserving protocols, and formal specification and reasoning.

Learning outcome

A. Knowledge:
1) Acquire an overview and understanding of the problems, notions, definitions, design principles and proof techniques for selected cryptographic protocols referred to in the "Academic content" section.
2) Insight into some typical applications of cryptographic protocols in networked systems, as referred to in the "Academic content" section.

B. Skills:
1) The ability to describe, analyse and construct cryptographic protocols.
2) The ability to apply proof techniques and automatic verification tools to existing and new constructions.

C. General competence:
1) Individually author a technical paper for publication.

Learning methods and activities

Lectures, colloquiums, assignments and self-study.

Portfolio assessment is the basis for the grade in the course. The portfolio includes an individual paper which counts 40% and an oral exam which counts 60%. The results for the parts are given in %-scores. The grading rule for the entire portfolio is pass/fail. The minimum passing grade is 70/100 points (70%).

The paper must be submitted and approved prior to the oral examination.

Compulsory assignments

  • Written paper assignment

Specific conditions

Exam registration requires that class registration is approved in the same semester. Compulsory activities from previous semester may be approved by the department.

Course materials

Established at the beginning of the course.


Detailed timetable


  • * The location (room) for a written examination is published 3 days before examination date.
If more than one room is listed, you will find your room at Studentweb.
