Method for quickly searching killing chain path based on complex network

The invention discloses a method for quickly searching a killing chain path based on a complex network. The method comprises the following steps: acquiring a combat network and a killing chain type character string; splitting the killing chain type character string to obtain single characters representing node types, and calculating a transfer matrix of adjacent node types in the combat network; sequentially multiplying all the transfer matrixes to obtain an arrival matrix; calculating traces reaching the matrix; extracting row and column serial numbers of non-zero elements in the transfer matrix, and constructing a directed network; and calculating to obtain a shortest closed path by using a complex network method, and outputting all non-repeated paths of the killing chain type. The invention also discloses a system for quickly searching the killing chain path based on the complex network. According to the method, a killing chain path is quickly searched for a complex combat network, systematization, scienti
