A Method of Processing-Storage Transmission Model-Based System Survivability Measure

摘要

Survivability is the capability of a system to fulfill its mission in the presence of attacks, failures, or accidents, and recover full service in a timely manner. On the basis of J. K. Millen's Survivability measure method, the paper sets the PST-based (processing-storage-transmission) Survivability system model, gives description of Survivability of PST-based Survivability systematic model, and proposes the algorithm of PST-based system Survivability measure. Finally, it composes a system based onprocessing, storage and transmission, and gets the data of system Survivability measure with the algorithm. It proves that the feasibility and validity of the method of PST-based system Survivability measure.
