Analysis of Cybersecurity Area Using e-CSTI

Abstract

Cybersecurity covers a wide range of areas including networking, software, hardware, cryptography, authentication, and cyberattack countermeasures. On the other hand, few cybersecurity experts are well familiar with all areas of cybersecurity. So, evidence-based analysis, such as the number of papers and patent families, is very important to understand the trends in the cybersecurity field without bias. However, few cybersecurity analyses are conducted in terms of both research papers and patent literature. In this paper, we focus on cybersecurity as a specialized field and conduct a detailed analysis of trends in the field of cybersecurity using e-CSTI, a research field analysis tool developed by the Japanese Cabinet Office, and Elsevier's bibliography. Specifically, we extract two representative clusters in the field of cybersecurity (cryptography and cyberattack countermeasures), clarify the structure of each paper cluster and patent cluster, and analyze the research trends and trends of hot topics in each country around the world at the cluster level.
