Identifying Recent Research Topics in Post-Quantum Cryptography via Topic Modelling

We collect the papers of Post-Quantum Cryptography (PQC) published from August 2022 to July 2023, which are able to be accessed on Web of Science. To get an idea what topics have mainly been researched about PQC for the recent one year, we employ topic modelling using Latent Dirichlet Allocation (LDA) approach. It is a popular method to extract topics from a collection of documents and divide them into the topics. Our LDA analysis classifies the selected PQC papers into six topics based on their similarities and extracts main keywords of each topic. The result supports us to be able to understand the recent research of PQC and find the future research directions.
