基于人工免疫结合余弦相似度的病毒特征提取算法
VIRUS FEATURE EXTRACTION ALGORITHM BASED ON THE COSINE SIMILARITY OF ARTIFICIAL IMMUNE SYSTEM
摘要
Abstract
The existing computer virus feature extraction algorithm cannot effectively extract unknown viruses and variants of the virus characteristics, thus a virus feature extraction algorithm based on the cosine similarity of artificial immune system is proposed with the help of artificial immune theory.Establishing the virus candidate gene bank by adopting TF-IDF to carry on the tendency extraction to the virus DNA in the code layer algorithm;using variable r matching rule to extract virus candidate gene pool to produce virus detection gene bank in gene layer algorithm.Finally, the program layer uses the cosine similarity algorithm to evaluate the similarity between the test program and the virus, and to recognize the test program.Simulation experiments show that the proposed algorithm has higher virus recognition rate compared with other virus feature extraction algorithms in the case of low false alarm rate.关键词
