摘要
随着网络的不断发展,传统的Internet网络体系结构越来越不能满足人们的实际需要。由于缺乏灵活性,传统网络制约了新协议和新应用的开发和应用。主动网是为彻底解决以上问题而产生的一种新型网络。主动节点具有一定的编程和计算能力。用户可以根据需要注入程序到网络节点,动态地发布协议或服务。由于主动网络的高度开放性,使其面临着巨大的安全性挑战。通过对国内外大量相关文件的阅读和分析,文章介绍主动网的相关概念,并对保护移动代码安全性的一般方法进行详细归纳和比较。
With development of the network, the traditional Internet network architecture is increasingly unable to meet the actual needs of the people. Due to lacking of flexibility, it limits the development and application of the new protocols. Active Network is a new type network and of the computing and programming capability. Users could inject customized programs and deploy customized protocols and services dynamically. Because of the high openness, the active network is facing huge security challenges. Based on reading and analyzing lots of related literatures both at home and abroad, this article presents the concept of Active Network, incuding the general methods for protecting the security of mobile code and the comparison of these methods.
