In the research of information security information security issues, many factors can cause the system to insecurity. In order to improve the accuracy of the risk assessment of information security, information security risk assessment model based on GA (genetic algorithm) and BP neural network is proposed. Using genetic algorithm to optimize the weights and thresholds of BP neural network to establish...
Before, people focused on how to judge the network security situation by expert experience. In order to accurately assess the security posture of networks in real time, we proposed a network security situation assessment model based on random forest (RF). This model is based on the idea of multiple classifiers combination, constituted by the decision tree, each tree relies on independent samples,...
In designated verifier signature, only the designated verifier can confirm the validity of a signature and it is applied widely in many environments such as electronic voting. However, most of designated verifier signature schemes cannot distinguish the real signer when the signer and the designated verifier arises a dispute on a signature. In other words, most of existing designated verifier signature...
