摘要：This paper proposes a new approach for image encryption using multi-dimensional orthogonal sequence. The sequence can provide an orthogonal transform for digital data, which is useful for image encryption. The key to decrypt is a set of the parameters to generate the sequence. For a gray scale image and a binary image, four different sequences are used to encrypt. Two of them are used to encrypt original image directly, the others are used for divided image. The experimental results show that this method has the characteristic of high security, because the number of the sequence is large and the digital image after encryption is noise-like and random Gaussian distribution.
