Cryptology is concerned with realising the impossible, namely securing information in open networks. This includes ensuring
- confidentiality of messages,
- integrity of messages,
- authenticity of principals.
The course gives an introduction to cryptology, its history and its use in modern computer systems. While the lectures are self-contained, some familiarity with basic algebra (Z/NZ, finite fields, cf. MAT552), networking (cf. INF557) is highly recommended. This course is part of the Cybersecurity track and a prerequisite for INF568.
To each lecture corresponds a TD, in which you apply the learnt concepts by implementing them in C.
The course is validated by a written examination. Moreover, many topics can be at the heart of a 3rd year project.
