Description: ieee一种基于混沌的新加密方法An Image Encryption Scheme Based on Chaotic Map
-
In this paper, a novel block digital image encryp-
tion scheme based on a chaotic coupled map lattices
(CML) is reported. Within this scheme, an original
image is decomposed into sub-blocks with a given size,
and an external secret key with 192-bit is used and
mapped to the system parameters, which are employed
to generate a spatiotemporal chaotic binary sequence
matrix to encrypt the block original image. Besides,
the former sub-block encrypted result will be acted as
a feedback to the following sub-block encryption proc-
ess. The proposed scheme is described in detail, along
with the security analyses such as key space analysis,
sensitivity analysis, information entropy analysis and
correlation coefficients analysis of adjacent pixels. The
computer simulation results indicate that the suggested
image encryption scheme has some properties desir-
able in a good security cryptosystem.

Description: 一种频域加密算法，图像经过DCT变换得到DCT系数，然后对DCT系数进行加密。然后对加密的DCT系数进行DCT反变换图像数据。最后对其加密后的图像数据进行线性变换来调整图像数据的取值范围在[0，255]。最后得到加密图像-A frequency-domain encryption algorithm, the image obtained through the DCT transform DCT coefficients, and then encrypt the DCT coefficients. And then encrypted DCT coefficients DCT inverse transform image data. The last of its encrypted image data linear transformation to adjust the image data ranges in [0,255]. Finally the image is encrypted
