Reducing the Key Size of McEliece Cryptosystem from Goppa Codes via Permutations
McEliece cryptosystem automorphism-incuded Goppa codes quasi-cyclic
font style='font-size:12px;'>

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 ...
DRANKULA: a McEliece-like rank metric based cryptosystem implementation
Code-based cryptography Public key cryptography Cryptosystem
font style='font-size:12px;'>
2018/8/28
We present and analyze the performance of DRANKULA, a McEliece-like cryptosystem implementation using \textit{rank metric} instead of Hamming distance. Namely, we use the scheme proposed by Loidreau i...

2016/1/25
We present a polynomial time structural attack against the McEliece system
based on Wild Goppa codes from a quadratic finite field extension. This attack uses the fact
that such codes can be disting...
Structural Cryptanalysis of McEliece Schemes with Compact Keys

font style='font-size:12px;'>
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...

2016/1/7
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
decoding. This is...
