摘　　要：分析目前移动平台信任传递存在的诸多缺陷,针对移动终端的特点及安全需求,提出了一种完整信任链模型,不仅能确保系统启动时的静态可信性,而且也能保障应用程序运行中的动态可信性。通过Dempster-Shafer原理计算信任值的方法验证分析,该模型能够有效解决信任度降低的问题,能增强平台可靠性,并且采用ARM微处理器对方案进行了实验验证。By analyzing the deficiencies of trust transfer in current mobile platform, a complete trust chain model for mobile terminal characteristics and safety requirements is proposed, the model not only ensure the static credibility in system start-up, but also protect the dynamic credibility during applications running. Through trust chain theory analysis, this model effectively solve the problem of the decreased confidence, and enhance platform reliability. Finally the ARM microprocessor is adopted to realize experimental verification on the scheme.
