The Fuzzy Efficiency Evaluation Method for XML Quadratic Blowup Attack

Aimed at the attack principle and features of XML quadratic blowup attack, the fuzzy evaluation method has been studied to evaluate the attack efficiency in this paper. The main procedures of the fuzzy evaluation method include choosing efficiency evaluation indexes, determining attack result set, and establishing fuzzy membership function. According to the fuzzy membership function, membership matrixes can be obtained by calculating, and index weights can be determined by judgment matrix method, which is one kind of the subjective assignment method. Finally, the fuzzy synthesis evaluation is carried out. Based on established evaluation model, sample data is collected and instance verification is conducted. The result shows that fuzzy evaluation method can evaluate the efficiency of network attacks scientifically and effectively.
