【摘要】：網(wǎng)絡(luò)受到攻擊入侵后容易出現(xiàn)信道失穩(wěn)和鏈路輸出失真,導(dǎo)致網(wǎng)絡(luò)的可靠性下降,因此提出一種基于自適應(yīng)均衡的受攻擊后的網(wǎng)絡(luò)可靠性估計(jì)模型。構(gòu)建網(wǎng)絡(luò)受攻擊后的傳輸鏈路模型,采用鏈路衰落調(diào)制方法減少網(wǎng)絡(luò)攻擊對(duì)傳輸信道的損害,對(duì)網(wǎng)絡(luò)傳輸信道進(jìn)行分段均衡處理,采用自適應(yīng)加權(quán)算法進(jìn)行鏈路失真補(bǔ)償,實(shí)現(xiàn)網(wǎng)絡(luò)鏈路自適應(yīng)均衡。仿真試驗(yàn)結(jié)果表明,采用該方法進(jìn)行受攻擊后的網(wǎng)絡(luò)可靠性估計(jì)提高了對(duì)網(wǎng)絡(luò)入侵的檢測(cè)能力,抑制了攻擊對(duì)網(wǎng)絡(luò)的信道損害,提高網(wǎng)絡(luò)安全性。
[Abstract]:The network is vulnerable to channel instability and link output distortion after being attacked, which leads to the decrease of network reliability. Therefore, a new network reliability estimation model based on adaptive equalization is proposed. The transmission link model after network attack is constructed, the damage of transmission channel is reduced by link fading modulation method, the network transmission channel is equalized in sections, and the link distortion is compensated by adaptive weighting algorithm. Network link adaptive equalization is realized. The simulation results show that the proposed method can improve the network intrusion detection ability, restrain the channel damage and improve the network security.
