基于网络的分布式计算为基于网络的PDM应用系统提供了底层技术支持,在一个开放的网络环境里,存在着不安全因素,如何保障构筑于其上的PDM系统的安全性是一个必须解决的问题,该文以所开发的某型号PDM系统(拟称为QH-PDM)为背景对网络环境下的PDM系统的安全保障问题进行了研究并提出解决方案和软件实现方法。
Network-based distributed computing provides the underlying technical support for network-based PDM applications. In an open network environment, there are insecure factors. How to protect the security of a PDM system built on it is a must. In this paper, the security of PDM system under network environment is researched and the solutions and software implementation methods are put forward based on the developed model PDM system (to be referred to as QH-PDM).
