摘　　要：通过对网页中的恶意脚本进行分析,提出了基于统计的网页恶意脚本检测方法,并利用主观赋权法的一种——判断矩阵法对不同的统计方法设置不同的权重,最后利用加权几何平均法对网页脚本统计结果进行完善,从而得出网页脚本的检测结果。实验证明该方法可以有效地检测网页中经过encode和unescape加密处理的恶意脚本。A vicious script in HTML was analyzed, and a vicious script detection method based on the statistics was proposed. The different weights for different statistic methods were set by a judgement matrix method which is one of the subjective weighting method, the statistic results of the script were perfected by a weighted geometric mean method, the detected results of the script were obtained. The experiment result shows that the method can efficiently detect the vicious script encrypted by encode and unescape.
