    摘要:

    網(wǎng)絡(luò )信息傳輸過(guò)程一旦出現波動(dòng),其加密和解密時(shí)間過(guò)長(cháng),使其傳輸負載超出最佳范圍。本文設計一種基于一維Logistic映射和二維Tent映射雙混沌思路的網(wǎng)絡(luò )信息加密方法。先采用時(shí)間序列分析的方式完成網(wǎng)絡(luò )穩定性分析:每個(gè)網(wǎng)絡(luò )信息特征序列都會(huì )隨著(zhù)時(shí)間的變化而變化。可依據網(wǎng)絡(luò )傳輸時(shí)間序列圖識別網(wǎng)絡(luò )的穩定性;然后根據其時(shí)間序列的穩定性分析結果,計算網(wǎng)絡(luò )傳輸的時(shí)間序列偏離度,結合偏離度參數利用雙混沌互反饋安全加密方法實(shí)現網(wǎng)絡(luò )數據加密,實(shí)驗結果表明:與對比方法相比,所提方法加解密時(shí)間較短,且傳輸負載均在最佳負載范圍內,驗證了該方法的可靠性強、安全性高。

    Abstract:

    Once the network information transmission process fluctuates, its encryption and decryption time is too long, making its transmission load beyond the optimal range. This paper designs a network information encryption method based on the idea of dual chaos of one-dimensional Logistic map and two-dimensional Tent map. First, we use time series analysis to complete the network stability analysis: each network information feature sequence will change with time. The stability of the network can be identified according to the network transmission time sequence diagram; Then, according to the stability analysis results of its time series, the deviation degree of the time series transmitted on the network is calculated. Combined with the deviation degree parameters, the network data encryption is realized by using the double chaos mutual feedback security encryption method. The experimental results show that compared with the comparison method, the encryption and decryption time of the proposed method is shorter, and the transmission load is within the optimal load range, which verifies that the method has strong reliability and high security.
