Objective: We discussed an image encryption arithmetic base on chaotic sequences. An image encryption tech- nique base on high dimension chaos sequence is proposed. Methods: First, initialize the high dimension chaos system to get the high dimension chaos sequences by using the discrete system iteration equation. Second, convert the high dimension chaos sequences and the original medical image to eight-bit binary system representation, separately. At last, performs an exclusive or operation on the corresponding elements of the two eight-bit binary system representation to get the encrypted image. Results: The experimental results indicate that the algorithm is effective, especially for medical images. Conclusions: Chaotic sequences have several good properties. The method was reliable and effective in gray, color and compressed medical image encryption.
