Abstract
With the development of mobile multimedia communication, the frequency of a few protocols and special communication protocols increases rapidly, and the probability of network attack events is frightening. This has caused people financial losses and psychological panic. At present, the commonly used protocol recognition tools use a single and targeted method, which has a lot of limitations. Based on the existing algorithms, this paper presents a new protocol feature extraction method, which greatly improves the efficiency of feature extraction. In this paper, the idea of Apriori algorithm is improved, and the feature string is searched under the idea of composite features of CFI algorithm. Combining the advantages of previous algorithms, a more efficient OFS (Optimal Feature Strings) algorithm is proposed, which can perform better when facing the feature extraction problem of bit stream protocol. Then it compares with the existing algorithms, tests the superiority of the new algorithm in running time, and further illustrates the accuracy and correctness of the algorithm.
