摘要:后量子密码正处于蓬勃发展时期，分析该领域的研究现状和热点，以便更好地把握密码学科新的研究方向。利用深度挖掘和分析软件（derwent data analyzer，DDA），运用文献计量学、关键词共现分析的方法，揭示后量子密码研究的整体趋势、地域分布、机构分布和研究热点。结果表明，后量子密码领域研究文献呈上升趋势，其中中国发文量世界排名第一，处于快速发展阶段。后量子密码领域研究主要集中在基于格理论密码、基于编码理论的密码、多变量密码、基于密码杂凑函数的签名等领域，其中基于格理论的加解密算法、数字签名算法、密钥协商协议、密码杂凑函数算法、全同态加密算法已经成为当今密码学科研究的热点。

Abstract:Post quantum cryptography is in a period of vigorous development.The analysis of current research status and hot spots in this field can help to better grasp the new research direction of cryptography.The software Derwent Data Analyzer，bibliometrics and keyword co-occurrence analysis methods were used to reveal the overall trend，regional distribution，mechanism distribution and research topic of post quantum cryptography.The results showed that the research papers in the field of post quantum cryptography were on the rise，among which the paper number of Chinese ranked first and was in the vigorous development stage.The research on post quantum cryptography mainly focused on the fields of lattice-based cryptography，code-based cryptography，multivariable cryptography and hash-based signature.Among them，encryption and decryption algorithms based on lattice theory，digital signature algorithms，key agreement protocols，as well as cryptographic hash function algorithms，fully homomorphic encryption algorithms have become the hot spots in the field of cryptography.

Key words:post quantum cryptography;bibliometrics;Derwent Data Analyzer;co-occurrence analysis;visualization
