摘要:物聯(lián)網(wǎng)的開放式部署環(huán)境和有限的資源,使其很容易受到惡意攻擊,而傳統(tǒng)入侵檢測(cè)系統(tǒng)又很難滿足物聯(lián)網(wǎng)自身的異構(gòu)和分布式特征。為了適應(yīng)開放式部署環(huán)境、資源有限類物聯(lián)網(wǎng)應(yīng)用需求,提出了一種基于模糊聚類c均值算法(fuzzy c-means,F(xiàn)CM)和主成分分析算法(principal component analysis, PCA)相結(jié)合的輕量級(jí)入侵檢測(cè)系統(tǒng)。相對(duì)于傳統(tǒng)入侵檢測(cè)方法,該方法能明顯減少測(cè)試數(shù)據(jù)的計(jì)算量。仿真實(shí)驗(yàn)結(jié)果表明,該方案能明顯縮短檢測(cè)時(shí)間并具有較高的檢測(cè)率。
