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.
