摘要： 针对数据同步过程中接入设备不合法和终端设备不稳定的问题，提出一种带身份验证和灾备功能的数据同步模型。该模型使用E-G方案管理密钥并进行身份验证。同步网络中的设备被定义为中心同步、灾备同步和成员同步3种角色，采用触发更新的方式交换数据。通过获得设备参数，计算优先级，从而选举灾备同步设备，实现设备角色无缝切换。应用结果证明了该模型的有效性。

Abstract: For the unauthorized access and unstable status of devices during the data synchronization process, data synchronization model with identity authentication and disaster backup function is presented. This model uses Eschenauer-Gligor(E-G) scheme to manage key while conducting authentication. Three roles, i.e. central synchronization, disaster backup synchronization and member synchronization devices existed in the synchronization network conform data switch with triggered update. Fetching main parameters of devices in the synchronization network, the model is calculated priority to elect backup synchronization device and perform seamless switch of different roles. Application result proves that the model is feasible.
