4.6. Attack against GRS codes
...In this session we will discuss the proposal of using generalized Reed-Solomon codes for the McEliece cryptosystem. As we have already said, generalized Reed-Solomon codes were proposed in 1986 by Niederreiter. Recall that these codes are MDS,...

4.3. Distinguisher for GRS codes
...In this session we will see that generalized Reed-Solomon codes behave differently than random codes with respect to the star operation. Thus we can define a distinguisher for Generalized Reed-Solomon codes. Let us recall the definition of...

4.4. Attack against subcodes of GRS codes
...In this session, we will talk about using subcodes of a Generalized Reed–Solomon code for the McEliece Cryptosystem. Recall that to avoid the attack of Sidelnikov and Shestakov, Berger and Loidreau proposed to replace Generalized Reed–Solomon...

4.2. Support Splitting Algorithm
...This session will be about the support splitting algorithm. For the q-ary case, there are three different notions of equivalence. The general one: two codes of length n are semi-linear equivalent if they are equal up to a fixed linear map. Each...

4.7. Attack against Reed-Muller codes
...In this session, we will introduce an attack against binary Reed-Muller codes. Reed-Muller codes were introduced by Muller in 1954 and, later, Reed provided the first efficient decoding algorithm for these codes. Reed-Muller are just a...

4.8. Attack against Algebraic Geometry codes
...In this session, we will present an attack against Algebraic Geometry codes (AG codes). Algebraic Geometry codes is determined by a triple. First of all, an algebraic curve of genus g, then a n-tuple of rational points and then a divisor which...

4.9. Goppa codes still resist
...All the results that we have seen this week doesn't mean that code based cryptography is broken. So in this session we will see that Goppa code still resists to all these attacks. So recall that it is assumed that Goppa codes are pseudorandom,...

4.5. Error-Correcting Pairs
...We present in this session a general decoding method for linear codes. And we will see it in an example. Let C be a generalized Reed-Solomon code of dimension k associated to the pair (c, d). Then, its dual is again a generalized Reed-Solomon...

4.1. Introduction
...Welcome to the fourth week of the MOOC Code-based Cryptography. Recall that we have mainly two ways of cryptanalyzing in the McEliece cryptosystem. We have Message Attacks, which address the problem of decoding a random linear code; these attacks...

Conférence #179 IEAoLu d'Emmanuel Dockès : " Pour un autre code du travail "
... s’est même accéléré avec les grandes lois du précédent quinquennat et les ordonnances de l’été. Dans ce contexte, un groupe d’une vingtaine d’universitaires (le Groupe de recherche pour un autre code du travail, GR-PACT), convaincu de la nécessité d’un droit...
