摘要:
基于编码的公钥密码由于能抵抗量子攻击和美国NIST后量子公钥密码算法的征集而受到越来越多的关注。本文主要围绕最近的基于编码的NIST抗量子攻击公钥密码征集算法,梳理基于编码的公钥方案具有的特点,即三种加密方式,三种重要的参与码类,三种安全性基于的困难问题,为对这方面有兴趣的科研人员提供一篇综述性论文。

Abstract:
Code-based public key cryptography has received more and more attention due to its resistance to quantum attacks and call for post-quantum public key cryptography by NIST.In this paper,we focus on the NIST submissions based on hardness of syndrome decoding problem,and study the characteristics of these code-based schemes,i.e.,three encryption methods,three important involving code classes,and three difficult problems.We provide a survey paper for those who are interested in this areas.
