I was reading an article about “Detecting Stingrays” at Schneier’s forum when I came across a post from Omar requesting a code review of an enhanced Rinjdael cipher developed in Iraq:
Omar A. Dawood, Abdul Monem S. Rahma, Abdul Mohssen J. Abdul Hossen,”New Symmetric Cipher Fast Algorithm of Revertible Operations’ Queen (FAROQ) Cipher”, International Journal of
Computer Network and Information Security(IJCNIS), Vol.9, No.4, pp. 29-36, 2017.DOI: 10.5815/ijcnis.2017.04.04
Details about the cipher can be found here (PDF):
It is a variant of AES/Rinjdael that uses S-Boxes, but with S-Box obfuscation.
