PROPOSED SOLUTIONS TO IMPROVE THE CODE RATE OF CODE-BASED CRYPTOGRAPHY

Abstract

This paper is mainly to analyse the feature of the McEliece cryptosystem, in which it gives a variety of solutions in order to enhace the effect of the algorithm such as using error vector and replace Goppa code which use in the traditional by succeed concatenated coding. The algorithm improves the coding rate about ~0.8, gain encoding 1.7dB and the security ability of McEliece algorithm improves more greatly than the traditional.
