IPv6环境下地震观测网络系统构建

Construction of Seismological Observation Network Monitoring System Based on IPv6

现有的地震观测网络系统都是基于IPv4协议开发的,由于IPv4地址的匮乏,无法对各个台站直接进行数据访问,只能进行台网级数据访问;另外,现有的地震观测网络系统只是简单的通过用户名和密码进行验证,而且传输时没有对用户名和密码进行加密,安全性低。通过研制基于IPv6协议的地震观测网络系统,开发出了新型的IPv6环境下地震观测系统组网协议,实现了台站级数据共享的目标;使用各种类型实时数据加密方法,保证了数据的完整性和机密性;建立了新型的证书管理和认证机制;在实验的基础上,开发出了现有基于IPv4的地震观测系统向IPv6的过渡技术,为下一步IPv6技术在地震行业的推广应用打下了良好的基础。

At the present,all seismological observation network systems are developed based on IPv4 protocol.Because IPv4 address is presented exhaustedly,we can′t access station data directly from the station-level,and can only access data from the network center.In addition,seismological observation network system now is verifying the user by way of ＂user name/password＂,and doesn′t encipher user name and password when transmitting data.It′s unsafe.By way of developing seismological observation network system based on IPv6 protocol,we developed new seismological observation system networking protocol under the IPv6 environment,and have accomplished the target of station-level data sharing;the integrity and confidentiality of data have been guaranteed by enciphering methods for real time data;new certificate management and authentication mechanisms have been set up.On the basis of experiment,we developed a transitional technology from IPv4 to IPv6,which provide a good basis for more application of IPv6 technology in seismological observation technology in the future.
