摘　　要：提出一种面向电子飞行包系统(EFBS)的数据交换模型。该模型采用星型逻辑结构进行数据传输,以XML格式通过数据交换组件实现其他子系统与中央内容管理单元的数据交换,介绍数据完整性检查机制,确保数据交换的安全性,其中,发送方通过DSA算法生成数字签名,并运用SHA-1算法获得文本摘要,接收方通过数字签名验证对交换数据进行完整性检查。实验结果验证了该检查机制的有效性。This paper presents a data exchange model of Electronic Flight Bag System（EFBS）.This model uses star-type logic structure to implement data transfer,and exchanges the message through data exchange components and central content management elements,then implements EFBS message exchange through a data exchange procedure designed with XML.A data integrity exchange procedure and an integrity check mechanism of EFBS are presented.In this mechanism,the sender generates digital signatures with DSA algorithm and the text summary is calculated by SHA-1 algorithm.At the receiver,the data integrity checking operation is conducted through digital signature verification consequently.Experimental results demonstrate the effectiveness and feasibility of this EFBS data integrity checking mechanism.
