摘　　要：安全数据交换主要指不同信息系统间数据的安全交换,数据在交换前的存在形式主要有数据库数据、文件数据、流媒体数据、请求响应数据四种,主要讨论在用网闸作为惟一连接点的网络中两个信息系统进行数据的安全交换,针对上述4种数据形式,可分别采用主动获取交换和被动接受交换两种方式。针对不同数据交换业务,在满足吞吐量、延时、并发业务功能性能需求的同时,根据不同数据形式的安全威胁选择合适的安全技术满足业务安全需求。主要比较分析了不同数据形式采用的不同交换技术,以及不同交换技术下存在的主要安全威胁,并总结了现有的安全技术手段。最后阐述了交换技术在新的技术推动下产生的新问题,并做了交换技术发展展望。Secure Data Exchange means exchange of various data between different information systems in a secure manner. Before exchange, data is stored in the forms of database data, flies, streaming media data, and request/response data. This article discusses data exchange between two networks connected only by a GAP device. Active [arching and passive accepting exchange modes are used for exchange of these four forms of data.Appropriate security technology for different types of data is used in order to reduce security threat, and to meet the functional and perform＆rice requirements such as throughput, latency, and concurrency. Different exchange technologies for different data forms and the main security vuinerabilities of every data exchange technology are discussed in this article. The present security technology is also summarized. In the last part, we examined the new problems incurred while the new data exchange technologies were used, and discussed the development outlook of secure data exchange .
