In order to improve the precision of network security situation prediction, a combined method for prediction was proposed. For the nonlinearity of network security situation value, the Method predicted the security situation by using ARMA model and Markov model. On this basis, it optimized the predicted results with combined strategy. The analysis of the example indicates that the combined method...
Wireless Sensor Networks (WSN) represent a new dimension in the field of networking. In this paper, an improved Genetic Algorithm is applied to the design of high performance multi-path routing protocol of WSN at the first time. The Algorithm consists of two stages: single-parent evolution and population evolution. The initial population is formed in the stage of single-parent evolution by using gene...
Traditional methods for evaluating network security neglect the correlation of network vulnerabilities. To solve this problem, a method based on Colored Petri Net (CPN) modeling is presented. Potential attack sequences are built according to the correlation of network vulnerabilities. The weakness and key paths can be found through analyzing the attack sequences. Simulation results show that the proposed...
