I am doing analysis of image encryption schemes for a project and want to analyse the cryptographic security of different image encryption schemes. It would be helpful for me if I can get Matlab codes for some of the popular schemes, right now I am having an implementation of AES based image cipher.
Dear Mousa F.
I have checked the codes at MATLAB File exchange, I can find only two suitable algorithms and one of them was already with me (AES). However, I have checked your papers and they are pretty interesting and I plan to implement them. It would be of great help for me if you can provide the codes or object file to me so I can perform the encryption according to test cases.
Dear Nisar Ahmed,
You can see this link http://www.mathworks.com/matlabcentral/fileexchange/index?utf8=%E2%9C%93&term=encryption
Moreover, you can easily implement some encryption algorithm in Matlab code, you can check some of my papers on chaos-based image encryption algorithms in C code

Dear Nisar,
Unfortunately, the code is registered to the AMP Visual TV company, Anyway you can implement the permutation equation and diffusion one in Matlab code easily, and when you need any help regarding point ask me
Thanks
Dear M. Swarnkar,
I have downloaded and checked the code. Can you please tell me the name of algorithm or the paper implemented in this code. In my observation, It was generating a key (key generation algo is not known) and doing XOR with the image.
Following matlab code help you for image encryption
PC=imread('lena_red1.bmp');
[row,col]=size(PC);
p=0.89;
t=2;
m=3;
k=1;
for x=1:row
for y=1:col
x1=mod(floor(x+t*y),row);
y1=mod(floor(x*m+(t*m+1)*y),row);
if(x1==0)
x1=x1+1;
end
if(y1==0)
y1=y1+1;
end
C(x,y)=PC(x1,y1);
k=k+1;
k
end
end
imwrite(C,'lena1.bmp','bmp');
imshow(C);
Dipankar Dey : Can you share the paper which has designed this algorithm.
You can download the code from this site;

Dipankar Dey : Your code gives a good encryption, but no decryption
Yes, I know that modulo can't be reversed, but can u suggest some other way to achieve decompression
Nisar Ahmed : I'd really recommend to watch this and try to build it by your own

if u get stuck ping me up on [email protected]
i'll try to help you out,
PS: i haven't done exactly as the video says, but yeah i am working on that part, and i haven't completed building the entire code yet.
