AbstractAdvanced Encryption Standard (AES) is a symmetric-key encryption each of
these ciphers has a 128-bit block size, with key sizes of 128, 192 and 256 bits. The AES cipher is specified as a number of repetitions of transformation rounds that convert the input plaintext into the final output of ciphertext. Each round consists of several processing steps, including one that depends on the encryption key[1,2]. This research proposes a technique intended to make the Advanced Encryption
Standard (AES) more safe and secure. Through the generation of random key, and permutation key sites in each round, instead of the process of expanding key locations in addition to the proposed permutation the plaintext before entering the encryption and inverse permutation for resulting ciphertext.
