基于LSB的图像中数据加密隐藏算法程序
图像的组成无非是一些字符串或者一些字节组成的字符串,然而,每一个字节数据位的重要度并不是一样的,两个相邻字节往往只有低位是不一样的。例如:00100110和00100111代表了两个不同渐变度的红色,但是就人眼是分辨不出来的。最低有效位LSB算法,就是利用这一点,达到图像压缩,或者数字水印的功能。
信息隐藏,即将信息嵌入某些载体,而使信息窃取者注意不到信息的存在。由于人眼的视觉的冗余及图像文件本身的数据量很大,数字图像文件是信息隐藏很好的载体,将需要保密的信…
包括的文件有:
findtext.m, hidetext.m, main.bmp, new2.bmp, message.txt, output.txt, gui.fig, new.bmp, gui.asv, gui.p, secret.bmp, read me.txt, screenshot.bmp, screenshot.jpg-err

pgp sdk optest
PGP Software Development Kit Cryptographic Module
Operational Test Notes
WHAT IS IT?
----------
The optest program is used as part of the FIPS 140-2 validation process.
In particular, section TE03.14.02 which requires that the tester shall
perform each of the specified services and observe that that they have
been implemented properly. As a side benefit to clients of the SDK
this code can also be used a good example of how to perform a number
of commonly used functions, whether or not the developer intends to run
in FIPS mode.
Depending on what option is chosen from the command line the following tests
will be run:
FIPS MODE SPECIFIC TESTS
------------------
- Invoke the Approved mode of operation (optest.c)
This involves Initializing the SDK, checking

TCL中的RSA算法
为了在NS2上的一些安全仿真,我试着介绍一下RSA算法。这个算法对WSN, MANET, VANET, FRID, BANET以及任何关注包安全性和数字签名的系统都非常试用。
