I have run this http://nevonprojects.com/aes-source-code-inmatlab/
AES on my audio file is giving me the error...... plaintext should be vector of 16 elements not a cell array. I have removed that error then I have compiled it again, now it is giving me the errors below......please help me in removing these error.
The errors are
??? Error using ==> bitxor
Inputs must be unsigned integers of the same class or
scalar doubles.
Error in ==> add_round_key at 14
state_out = bitxor (state_in, round_key);
Error in ==> cipher at 97
state = add_round_key (state, round_key);
Error in ==> aes_demo at 41
ciphertext = cipher (plaintext1, w, s_box, poly_mat, 1);
The first error is due to the type of data that you are passing to the routine. If you are passing PCM values, this are signed small ints.
The code is asking for unsigned integers. I think that once you solve this problem through a proper conversion to unsigned values the other errors may disappear.
I think the correction of first error is caused the second error pleas post the code to view it and suggest the solution
