    • The present invention discloses a bus monitor for enhancing SOC system security and a realization method thereof. The bus monitor disposed between a system bus and a system control unit includes a configuration unit, a condition judgment unit, an effective data selection unit, a hardware algorithm unit and a comparative output unit. Without affecting the bus access efficiency, the present invention provides the method capable of immediately monitoring the bus behavior, and the detection system notices whether a particular bus access serial behavior is changed due to an accidental fault or intentional attacking fault. If the particular bus access serial behavior is changed, the present invention warns the system to adopt a suitable security measure to prevent the security hidden trouble and leakage of classified information due to the incorrect system security process.
    • 本发明公开了一种用于提高SOC系统安全性的总线监视器及其实现方法。 布置在系统总线和系统控制单元之间的总线监视器包括配置单元,条件判断单元,有效数据选择单元,硬件算法单元和比较输出单元。 本发明不影响总线访问效率,提供能够立即监视总线行为的方法,并且检测系统注意到由于意外故障或故意攻击故障特定的总线访问串行行为是否改变。 如果特定的总线访问串行行为发生变化,本发明警告系统采取适当的安全措施,以防止由于不正确的系统安全过程导致的安全隐患和分类信息的泄漏。
