Cryptography matrix examples
WebRecall that the adjoint of a complex matrix is the complex conjugate composed with the transpose (see terminology section for details). Hence, because a complex number can be considered as a single-entry matrix, its transpose is itself, so that its adjoint is its complex conjugate. In polar form, the complex 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 …
