摘　　要：随着Internet的迅速发展和广泛应用,网络和信息安全越来越受到人们的高度重视。防火墙作为一种网络与系统之间强制实行的访问控制机制,是确保网络安全的重要手段。但是当敏感信息通过防火墙进入开放的网络进行传送时,如何保证这些敏感信息的完整性和保密性,防火墙就无能为力了。为此,需引入加密技术来保证其完整性和保密性。加密技术与防火墙技术的强强联合,将使网络安全得以增强并在一个更大的范围得以实现。如何构建一个具有加密机制的防火墙是本篇论文研究的重点。With the rapid development and wide application of Internet,network and information security draws more and more attention.As an enforced mechanism of control and access between network and system,firewall becomes an important means to ensure network security.However,when sensitive information is being transferred through public network,firewall becomes powerless to ensure their integration and confidentiality.Therefore,it is very important to introduce encryption into firewall technology to fulfil this task.The combination of firewall technology and encryption will not only enhance the network security,but extend it to a much wider range.This thesis aims at studying how to build a firewall with encryption.
