WebOct 12, 2024 · The design of a practical code-based signature scheme is an open problem in post-quantum cryptography. This paper is the full version of a work appeared at SIN’18 as a short paper, which introduced a simple and efficient one-time secure signature scheme based on quasi-cyclic codes. As such, this paper features, in a fully self-contained way, an … Webthe operation such that, the probability of the observed noise in S is maximized. Computing this probability requires the adversary to model both the intrinsic signal and the noise probability distribution for each operation accurately.
