英文摘要：

The autonomous recognition mechanism on survivability is still in the ascendant,and the cognition is the realization premise of the recognition. A cognitive evaluation mechanism for survivable system was proposed based on the shortest K-path algorithm. Firstly,a framework structure of the cognitive evaluation for survivable system is established,the cognitive state transfer matrix and cognitive evaluation index are given. Then,a quantitative model for the cognitive survivability of the system is made. Finally,a cognitive performance simulation experiment in some network security situation awareness system is carried out under Do S attacks. Experiment shows that the presented method faithfully reflects the dynamic evolution of cognitive performance under different attack parameters,analyses the survival threat of the system and validates the effectiveness of the proposed method.
