Improved Solvers for Code Equivalence Problems
code-based cryptography
Description
Due to the recent advances in quantum computers, the search for cryptosystems that survive quantum attacks is of great interest. Code-based cryptography is a promising candidate, since it is build on the NP-hard problem of decoding a random code [1].
The McEliece cryptosystem is a promising candidate for asymmetric encryption.
However, many attempts at constructing a code-based signature scheme have resulted in impractical parameters or security problems.
NIST's announcement of a competetion dedicated to standardizing post-quantum signatures has lead to the publication of several new code-based schemes
In this work we consider LESS [2] a signature scheme based on the hardness of the code equivalence problem [3]. State-of-the-art solvers of the problem [4] are analysed and modifications are made to improve their performance.
