Internet的出现引起了现代计算方式的变革,分布式计算已成为现代计算方式的主流。Internet和分布式计算在给人们带来好处的同时,也由于它自身的分布式特点给人们带来了前所未有的安全问题。随着Internet的快速增长和分布式计算的不断扩展,人们越来越注重个人和企业计算环境的安全。Java语言的出现开辟了人类编程方式的新纪元,Java由于能够提供“一次编成,到处运行”(Write Once,Run Anywhere)的好处,因而已经成为事实上分布式应用的标准开发平台。由于Java本身就是针对Internet和分布式计算的特点而设计的,因此它在设计时就内置了强大而又灵活的安全机制,本文简要分析Java的安全机制。
The emergence of the Internet has led to the change of modern computing methods, distributed computing has become the mainstream of modern computing methods. Internet and distributed computing bring benefits to people at the same time, but also because of its own distributed features to bring unprecedented security problems. With the rapid growth of the Internet and the continuous expansion of distributed computing, people pay more and more attention to the security of personal and enterprise computing environments. The advent of the Java language has opened the door to a new era in human programming that has become the de facto standard development platform for distributed applications by offering the benefits of Write Once, Run Anywhere. Because Java itself is designed for the characteristics of the Internet and distributed computing, it built a powerful and flexible security mechanism at design time. This article briefly analyzes Java’s security mechanisms.
