冶金类Web数据库在物理隔离网络间安全同步的方法研究

Study the way of the security database synchronization between physical isolated networks of Web-based metallurgy database

为了提高各类冶金数据库研究安全性,与互联网物理断开的内部网络成为这些数据库存放的主要网络环境。在对外发布共享的业务需求时,需要在互联网上放置一个冶金数据库作为安全网络上数据库的子集(部分内容的数据库),用于把可公开的相关数据发布出来。为了在两个没有物理连接网络间把数据库的数据进行单向或双向的同步,我们设计了一个安全数据摆渡机制。该设备同时连接到两个网络,但内部并没有任何的物理连接,它的作用就是同时只连接一个网络,把需要传输的数据取走和传送到另外一个网络来完成一个完整的摆渡过程。这样大大提高了数据库的研究安全性,能提供较好的数据库同步实时性,为整个冶金类数据库提供了另外一种可采用的研究方法。

In order to advance the security of all kinds of metallurgy databases, the internal network which is disconnected from intemet in physical way is a major network environment of these databases storages. When we need to release and share the data and operation, we also need a metallurgy database to be a subclass of the metallurgy database which is located in a safe network. We can use this way to release the data which can be opened. In order to finish database synchronization in unilateralism or bidirectional way between physical isolated networks. This equipment is connected to two networks, there no any connections in it. It can transport data to another network only through one network in one time to finish a whole ferry process. This way advances the research security greatly which can provide good real time capability of database synchronization. This way also provides another research way we can use in all metallurgy databases.
