Title : New results in code-based cryptography
Abstract : In this talk, I will introduce the notion of code-based cryptography, I will detail the McEliece and Niederreiter and describe some identification and signature schemes based on hard problems of coding theory namely the syndrome decoding problem. Then, I will describe an identity-based signature scheme provably secure in the ROM, a threshold ring signature scheme and I will conclude by describing the good properties of the Stern scheme with respect to some side-channel attacks (like SPA and DPA).
