【摘要】 入侵容忍数据库的复杂性主要是由破坏扩散所引起的。由于检测延迟、破坏评估延迟及破坏修改延迟造成的破坏扩散对于入侵容忍数据库系统实现数据的完整性、一致性和可用性构成严重挑战。针对各种延迟造成的破坏扩散,提出了将入侵隔离技术和多阶段控制技术相结合实现一个入侵容忍数据库系统的改进架构,可以有效地解决破坏扩散问题。更多还原

【Abstract】 The complexity of intrusion tolerance database system is mainly caused by a phenomenon called damage spreading. The da- mage spreading caused by detection latency, evaluation latency and repair latency seriously do harm to integrity, consistency and avai- lability of intrusion tolerance database system. According to damage spreading caused by various latency, a new frame is introduced, for intrusion tolerant database system integrated intrusion isolation and multi phase containment to solve damage spreading.更多还原
