基于组件的密码学虚拟实验室的设计与实现

基于组件技术的密码学虚拟实验室(CVL)以Java Applet实现客户端,以JavaBean的形式开发密码算法组件,利用Java反射技术实现了系统组件的动态分析,采用XML技术实现了实验组件信息的保存,结合计算机图论中的有向无环图的概念和Java线程机制,提出了一种基于有向无环图的管理线程控制机制,较好地反映了组件之间的数据依赖关系和运行管理过程.CVL实现了可视化实验流程的定制,实验流程的保存与读取以及密码算法的验证和性能分析性等功能.为科研、教学提供了一个很好的密码学实验平台,并给从事仿真系统开发的研究者提供了有力的参考模型.

Design and implementation of cryptology virtual lab based on component

A design model and implementing method of CVL(cryptology virtual lab) is proposed based on component techniques.In this model,the client is implemented with Java applet,cryptology algorithms are developed with JavaBean.The dynamic analysis and save operation of component information can be achieved by using Java reflection and XML technique.A management control mechanism based on DAG is presented,which is implemented by Java thread scheme and the concept of DAG in graph theory.The mechanism better reflect t...
