MATLAB: Is it possible to implement AES algorithm in simulink

aessimulink

I have already implemented it in matlab code. I just wanted to know if is it possible to create a simulink block with the AES algorithm code.

Best Answer

Yes, it can be done in Simulink.

And that is all we can say on the topic. Due to US law, we are not allowed to tell you how to implement AES. But we can tell you that someone has published a paper on the topic

Note that due to US laws, we are not able to discuss the implementation of AES in this forum. However, your question does not depend upon the implementation of AES, so it can be discussed.

You will need to pack your bits together into 8 bit bytes and encrypt the sequence of bytes; then unpack the sequence of encrypted bytes to form a sequence of bits.

ByteVector = bin2dec( char(reshape(BitVector, 8, []).' + '0') );

But first you have to pad BitVector out to a multiple of 8 bits.

Then you can encrypt ByteVector. Then afterwards

EncryptedBitVector = reshape( dec2bin( EncryptedByteVector, 8) .' - '0', 1, [])

This will almost certainly be longer than the original vector due to the way that AES works.
