Secure Channels (Course)

LecturerProf. Dr. Stefan Lucks

A secure channel, between two or more participants, provides privacy and integrity of the transmitted data. The goal of this course is to understand the principles of designing and analyzing secure channels. The students will learn to distinguish between a secure and an insecure design, by conceiving the basic ideas of secure channels:

  • Formalizing the security requirements
  • Analyzing existing protocol and channel designs
  • How to prove the security of a given design
  • Sound implementation of secure channels
