Code-based public-key cryptosystems for the post-quantum period

Code-Based Public-Key Cryptosystems were been considered in this work. In addition, the current state, the existing contradictions and prospects of practical use for the post-quantum period were been studied. The authors have proposed new scheme of crypto-transformation that significantly exceeds the relative speed of information transmission. An advantage of the proposed scheme compared with the well known the McEliece and Niederreiter schemes has shown.
