The other day I saw this Hybrid Cryptographic Algorithm in the Google and felt curious about it. I am trying to understand this Hybrid Algorithm. And hopefully its not so hard to understand whats going on until AES portion comes up. Here in this research paper the author gives 48bytes input to AES and gets 88byte output from AES.
I hope the author won't mind that I copied a part of the image and gave it in here.
My question is, How is this possible? AES always gives cipher size that is divisible by 16. But 88byte is wired! Can anyone help me by explaining or giving a hint what might be the way to achieve this?
