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.
