目前访问涉密网中地理空间信息服务的传统做法，是使用网闸、防火墙等安全手段实现公网与涉密网的通讯连接。但由于涉密网与公网之间的物理隔离被逾越，必然造成涉密网络的安全隐患。在某省级空地一体化土地动态监测项目中，提出了一种基于短信的异步通信协议，采用对地理空间信息数据压缩加密的处理方法，降低数据敏感度和被监听风险，保障了数据安全，实现了在野外数据通信严苛条件下对涉密网络内的地理空间信息服务的有效访问。

At present, the traditional way of accessing to the classified network of geographic spatial information services is using network gateReeper, firewall and etc to ensure the public and classified network communications links. However, the physical isolation between classified network and public network is crossed, which is bound to cause classified network potential security hazard. In provincial space land dynamic monitoring integration project, it proposed the point to point text message communication protocol and asynchronous transmission mechanism. Using geo-spatial information encryption processing and data compression processing method, it reduced the risk of data and ensured data security, which realized geographic spatial information communication effectively in the field conditions.
