Base64 加密算法（Author 蒋柏良 Jerry Jiang)
Base64 加密算法（Author 蒋柏良 Jerry Jiang)-*
* DESCRIPTION
* Base64 processes input in 24bit chunks by converting each chunk into 4
* bytes of output. It does so by splitting input into four 6bit groups and
* using these as indexes in the following substitution table-
* const char base64_map[] =
* "ABCDEFGHIJKLMNOPQRSTUVWXYZ"
* "abcdefghijklmnopqrstuvwxyz"
* "0123456789+/"
* If an input is not a multiple of 3 bytes, it s padded with zeros. In
* this case the output bytes that consist entirely of the pad data are
* replaced with = .
*
* Example
* An input of 0x00 0x45 0xF2 is equivalent to 00000000 01000101 11110010
* bit sequence, which s then split into 000000 000100 010111 110010
* and these are substituted to produce the following base64 encoding
* A E X y
*
* RETURN VALUE
* b64_length() should return output length for the input of len bytes.
* b64_encode() should encode len bytes from src int

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
