Using Cipher Key to Generate Dynamic S-Box in AES Cipher System

The Advanced Encryption Standard (AES) is using in a large scale of applications that need toprotect their data and information. The S-Box component that used in AES is fixed, and notchangeable. If we can generate this S-Box dynamically, we increase the cryptographic strength ofAES cipher system. In this paper we intend to introduce new algorithm that generate S-Boxdynamically from cipher key. We describe how S-Box can be generated dynamically from cipherkey and finally analyze the results and experiments.
