Simplified AES (S-AES) is an educational alogrithm designed by Edward Schaefer to help students understand the structure of AES. The diagram below gives a high level overview of the encrpytion and decryption process:
plaintext = 0b1011000100101110 # 16 bits
key = 0b1101101000111010 # 16 bits
ciphertext = encrypt(plaintext, key)
plaintext = decrypt(ciphertext, key)The PDF that explains the implemented of S-AES is included in this repository and can be found here.
