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

代码做了什么？有时我们可能希望隐藏我们的文件内容从其他…
What Does the code DO? Sometimes we may desire to hide our file contents from others.One of the possible way is encrypting these files.Here a simple encryption technique is used(In VB - The same technique can be implemented in "c" also.) Program flow Explained * Open the File to be encrypted for Binary Access Read(Say Source File) * Open a temparory file where encrypted data is stored for Binary Access Write(Say Destination File) * Loop through the Source File Byte by Byte * For each byte read from the file, Complement the data. (Using Not operator (in C we have to use "~" operator) * Write Complemented Data to Destination File * Delete the Source File * Rename Destination file as Source File(Now Encryption is over) -What Does the code DO?
