| 摘 要： | 提出了混沌映射与矢量码书相结合的加密算法。首先由密钥控制混沌映射生成相应的置换矩阵；然后对矢量量化形成的码书分块加密；再将加密码书与索引集合分别进行传输。仿真试验表明，相对于码书索引集合的加密。该算法效果更好。

| Abstract: | In this paper, an image encryption algorithm based on chaotic mapping and vector quantization is presented. First, the real number value chaotic sequences using the key value is generated, which is dispersed into transformation matrix; Then the codebook that is generated by vector quantization is blocked and encrypted; Our scheme sends the set of indices and the encrypted data of the codebook. It is better than encrypting the sets of indices on the codebook. |
