【摘要】 根据计算机网络出现的安全问题 ,分析了现有的网络安全机制。并重点讨论了防火墙技术在网络安全控制中的应用。在此基础上提出了一种根据路由表记录情况决定数据安全性的防火墙可靠性增强算法。该算法采用记录 IP数据报路由和设置不安全 IP地址 ,通过地址比较的办法来确认数据报的接收与抛弃。同其他同类算法比较具有实现简单、自适应性强、安全可靠等特点。为防火墙技术的进一步研究探索了一条新的途径更多还原

【Abstract】 The paper analyzes today’s focus on the network security and discusses the principle to some extent . On the basis of these analyses and discussion, the firewall of internet security is also presented, and an advanced way is shown in the paper. By recording message’s IP address and configing defused IP address,the message will be received or not according to comparing these IP address. Comparing to others,the arithmetic is simple implement, better adaptive and reliable. The arithmetic will influence today’s technolodge of firewall strongly.更多还原
