Aimed to improve the secure performance of traditional mediator/wrapper architecture, it was pro-posed an information integration model with multi-mediator.Adopting multi-mediator collaboration technology, the model could dynamically elect a mediator to deal with the query according to status and performance of me-diators and least-wait-time policy, so that the model was not only secure, but also efficient.%针对传统中介器/包装器（ mediator/wrapper）结构上的安全问题，提出了一个多中介器的安全信息集成模型。该模型采用多中介器协作技术，根据当前系统的状态和各中介器本身的性能，以最少等待时间为调度原则，动态选举最优的中介器完成查询任务。该模型既可保证系统的安全性，又可提高系统的效率。
