摘要
现有的网络地址自动配置缺乏自动检测的手段和认证机制,在进行地址配置过程中无法有效保证其安全性。随着网络设备数量的逐渐增加,仅仅依靠手工的方式进行配置会增加出错率。针对存在的这些问题,本文提出了一种基于LLDP的自适应网络拓扑测量算法,通过仿真实验的方式,验证该算法的准确度。针对DHCP中存在的安全漏洞,提出了一种基于OTP机制的安全认证模型,通过对比验证得到,该模型可以保证DHCP协议安全。在以上方法的基础上,设计了一款网络地址自动配置系统,并采用分层的体系架构实现网络地址的自动生成功能。
The existing network address automatic configuration lacks the means of automatic detection and authentication mechanism,and can not effectively guarantee its security in the process of address configuration.With the gradual increase in the number of network devices,only relying on manual config uration will increase the error rate.To solve these problems,an adaptive network topology measurement algorithm based on LLDP is proposed.The accuracy of the algorithm is verified by simulation experiments.Aiming at the security vulnerabilities in DHCP,a security authentication model based on OTP mechanism is proposed,which can ensure the security of DHCP protocol through comparison and verification.On the basis of the above methods,an automatic network address configuration system is designed,and a hierar chical architecture is used to realize the automatic generation of network addresses.
