The Study of the Optimal Method for Tibetan Information System Security Resource Allocation

In order to improve the accuracy of Tibetan information system security investment, given the characteristics of Tibetan information resources, using the theory and method of complex network, from the characteristics of information resources based on the perspective of Tibetan language, established safety resource allocation model based on attacking propagation and the risk of security investment. Based on the model, simulation experiments, the result shows that the model can be used for Tibetan information system to attack the effective protection fi＇om attack propagation, to improve the accuracy and practicability of the safety investment of the system.
