Abstract: The main object of this reseach is to reveal the overall situation of the international cloud computing security technology field, the research status and hot spots of the main participating countries and regions, the main funding institutions, the main hosting institutions, the dominant disciplines, and the statistics and analysis of the main research directions of cloud computing security in China. Taking the scientific research achievements in the field of cloud computing security technology in the global scientific research project database as the research object, this paper uses the bibliometric method to make statistics and analysis on the data of related scientific research projects from 2011 to 2020. The results show that in the past 10 years, cloud computing security research projects show a fluctuating downward trend, the United States and the European Union have the most investment in scientific research, and medical science and information science are the leading direction of scientific research.

Key words: cloud computing security; , participating countries; , research project; , statistical analysis
