The analysis of measurement method in the knowledge system of network security based on information entropy

The knowledge system of network security is the core of the Education of Network Security Literacy, which is the theoretical basis of quantitative evaluation and education. In order to build a scientific, systematic and pertinent knowledge system, the paper develops the measurement method based on information entropy, presents the library of network security knowledge, puts forwards the definition of the knowledge function, discusses the authentication of its nature and the method selection of knowledge system based on position demand. The paper also takes a real example to verify the algorithm, finally the quantitative method of the knowledge system is also put forward to providing a reference for the engineering practice of network security education.
