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

山排序算法:基本思想:全序无序分离…
希尔排序算法:
基本思想:将整个无序序列分割成若干小的子序列分别进行插入排序。 序列分割方法:将相隔某个增量h的元素构成一个子序列。在排序过程中,逐次减小这个增量,最后当h减到1时,进行一次插入排序,排序就完成。增量序列一般采用:ht=2t-1,1≤t≤[log2n],其中n为待排序序列的长度。-Hill sorting algorithm: the basic idea: the whole sequence disorder is separated into a number of small sub-sequences respectively Insertion Sort. Sequence segmentation method: h will be separated by an incremental elements constitute a subset of sequences. In the sort process, the successive decrease of the increment, and finally reduced to one when h when an insertion sort, sort completed. Incremental sequence generally use: ht = 2t-1, 1 ≤ t ≤ [log2n], in which n is the length of sequence to be sorted.
