    • Construction of S-Box based on chaotic map and algebraic structures 

      Hussain I.; Anees A.; Al-Maadeed T.A.; Mustafa M.T. ( MDPI AG , 2019 , Article)
      The Advanced Encryption Standard (AES) is widely used in different kinds of security applications. The substitution box (S-box) is the main component of many modern symmetric encryption ciphers that provides confusion ...

    • A novel method to generate key-dependent s-boxes with identical algebraic properties 

      Ahmad Y., Al-Dweik; Hussain, Iqtadar; Saleh, Moutaz; Mustafa, M.T. ( Elsevier , 2022 , Article)
      The s-box plays the vital role of creating confusion between the ciphertext and secret key in any cryptosystem, and is the only nonlinear component in many block ciphers. Dynamic s-boxes, as compared to static, improve ...
