I'm working on image encryption using AES algorithm in MATLAB (128 bits, works by processing blocks of 16 bytes, pure implementation), I'm having some difficulties like making a loup that takes every 4*4 matrix from the general matrix (n*m)
ex: I have an image size=17666, so (17666/16)= 1104*16 + 2, so 1105 ciphertexts corresponding to my 1104 first block encrypted as they are, followed by the last (2 bytes), so how to complete the last by filling in with zeros to obtain a block of 16 bytes.
Dear Himich Ayoub
i think using c# in encryption easier there are built in function for encryption so you can only call an use it for your work
or you can use nested loop and determine step to increase your index by 4 for each new loop to prevent overlapping in the processing
Padding technique can be used. Where you can add an extra (14) dummy pixel value in the image.
