论文摘要
在本文中，算法旨在根据语音功能，秘密共享方案和电磁转子机制作一个密码系统，以制造灰度图像的密码系统。在这里，Shamir Secret共享（K N）阈值方案用于保护键以及（N K）用户的语音功能。键流由语音样品的系数模制，使用此键流，转子机旋转圆柱位置是初始化的，并且内部布线由伪随机数的Henon Chaotic Map决定，其中Chaotic System的初始种子是从Keystream中选择的。此外，密钥流的股票在用户之间分配。语音处理与电磁机融合，以提供身份验证以及基于组的加密。感知线性鉴定（PLP）系数用于形成秘密密钥。仿真实验和统计分析表明，所提出的算法对加密图像的初始秘密按键，熵，平均值分析和直方图敏感。因此，拟议的计划在任何脆弱情况下都可以抵抗。
In this paper, an algorithm is aimed to make a cryptosystem for gray level images based on voice features, secret sharing scheme and electromagnetic rotor machine. Here, Shamir secret sharing (k n) threshold scheme is used to secure a key along with voice features of (n k) users. Keystream is molded by coefficients of a voice sample, using this key stream, rotor machines rotating cylinders positions are initialized and internal wiring is decided by pseudo random number of Henon chaotic map, where initial seed for chaotic system is chosen from keystream. And furthermore, shares of key stream are distributed among users. Speech processing is fused with electromagnetic machine to provide authentication as well as group based encryption. Perceptual linear predication (PLP) coefficients are utilized for formation of secret key. Simulation experiments and statistical analysis demonstrate that the proposed algorithm is sensitive to initial secret keystream, entropy, mean value analysis and histogram of the encrypted image is admirable. Hence, the proposed scheme is resistible to any vulnerable situation.
