Archived course open to registration
« In the context of the Coronavirus virus outbreak », this archived course remains open to registrations although it is not facilitated by the course teachers: its contents are no longer updated and may therefore no longer be up to date. The last version of this Mooc Code-Based Cryptography dates back to June 2016. If you register, you can freely consult the read-only resources but all collaborative spaces are closed (forums, wiki and other collaborative exercises): you cannot interact with the teaching team or with other learners. Furthermore, you will not be able to obtain an attestation of achievement for this course.
About This Course
We all use cryptography in our daily lives. The security of the most popular Public-Key Cryptosystems are based either on the hardness of factoring or the presumed intractability of the discrete logarithm problem. Advances on these problems or the construction of large quantum computers would dramatically change the landscape: Code-Based Cryptography is a powerful and promising alternative.
The objective of this course is to present the state of the art of these cryptosystems. This MOOC covers the essentials that you should know about this hot topic in Cryptography and Coding Theory: the security-reduction proofs, the possible attacks, several proposals to reduce the key-size, etc.
Week 1: Error-Correcting Codes and Cryptography
Week 2: McEliece Cryptosystem
Week 3: Message Attacks (ISD)
Week 4: Key Attacks
Week 5: Other cryptographic constructions relying on coding theory
