Abstract: This paper discusses the experimental education of cryptology in the course system of information security and the problems existed in the current virtual laboratory (VL) construction,and proposes the design model and implementing method of VL platform of cryptology based on components.Using this experimental system,the users can customize the experimental flow,verify the algorithm written by themselves,and extend the experimental components.The components are developed with JavaBeans,which not only improves the efficiency,realizes the reuse of software,but also makes the laboratory easy to extend and carry through secondary development,so as to provide a good virtual experimental platform of cryptology for scientific research and teaching.

Key words: virtual laboratory, cryptology, component
