研究背景与意义在数字化时代图像作为信息传递的核心载体广泛应用于军事通信、医疗影像、金融数据等关键领域。然而网络传输的开放性导致图像信息面临窃取、篡改、伪造等安全威胁传统加密算法如 AES、DES因图像数据的高冗余性、强相关性和大容量特性存在加密效率低、密钥空间不足等问题难以满足实时安全需求。混沌系统因对初始条件和参数的极端敏感性、伪随机性强、遍历性好等特性与密码学中的混淆、扩散原则高度契合成为图像加密的理想技术支撑。正弦 - 余弦Sine-Cosine混沌映射作为一种典型的二维混沌系统相比 Logistic 映射等一维混沌具有更复杂的动力学行为和更大的密钥空间能生成更优的随机序列。本算法基于正弦 - 余弦混沌映射生成加密密钥流对 RGB 图像三通道分别执行 “行移位 - 列移位 - XOR 异或” 三重操作实现高安全性、高效率的图像加密与解密为图像信息安全提供新的解决方案。1.2 核心目标与创新点核心目标构建基于正弦 - 余弦混沌映射的随机序列生成机制确保密钥流的伪随机性与不可预测性设计 “行移位 - 列移位 - XOR 异或” 三重加密流程打破 RGB 图像三通道的空间相关性与灰度关联性实现加密算法的可逆性确保解密后图像无失真恢复验证算法在安全性、加密效率、抗攻击能力等方面的优越性。创新点采用正弦 - 余弦混沌映射通过双参数调控提升密钥空间复杂度抵御暴力破解针对 RGB 三通道独立加密避免通道间干扰增强加密强度三重加密操作层层递进移位操作破坏像素空间分布异或操作混淆像素灰度值实现 “双重混淆 双重扩散”算法流程简洁无需复杂矩阵运算兼顾安全性与实时性。二、正弦 - 余弦混沌映射原理⛳️ 运行结果 部分代码clc; close all; clear
