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. Platform: |

Description: A block-based transformation algorithm is proposed for image
security using a combination of image transformation and encryption techniques.
This algorithm will be used as a pre-encryption transform to confuse the relationship
between the original images and the generated ones. The generated (transformed)
images are then fed to the Blowfish encryption algorithm. Correlation, histogram,
and entropy have been used to measure the security level of the images. Platform: |
