Reducing the Key Size of McEliece Cryptosystem from Goppa Codes via Permutations
McEliece cryptosystem automorphism-incuded Goppa codes quasi-cyclic
2018/11/2
In this paper, we propose a new general construction to reduce the public key size of McEliece-based schemes based on Goppa codes. In particular, we generalize the ideas of automorphism-induced Goppa ...

that such codes can be disting...
Structural Cryptanalysis of McEliece Schemes with Compact Keys
public-key cryptography McEliece cryptosystem algebraic cryptanalysis
2016/1/25
A very popular trend in code-based cryptography is to decrease the public-key size by
focusing on subclasses of alternant/Goppa codes which admit a very compact public matrix, typically
quasi-cyclic...
We present a new family of linear binary codes of length n and dimension k accompanied with
a fast list decoding algorithm that can correct up to n

We show that the plaintext of some of the proposed CCA2 conversions of McEliece cryptosystem
with a public key in systematic form can be recovered faster than with a general linear
