WebbBACKGROUND OF SM4 S-BOX ON CFA Arithmetic (CFA), mixed basis The algebraic expression is shown as (1) and properties of the S-box for SM4 algorithm has been analyzed in [9]. (1) I. INTRODUCTION S (x) I x A C A C 8 M4 algorithm is a group symmetric cipher algorithm where I is the MI over GF (2 ). The SM4 cipher has a key size and a block size of 128 bits each. Encryption or decryption of one block of data is composed of 32 rounds. A non-linear key schedule is used to produce the round keys and the decryption uses the same round keys as for encryption, except that they are in reversed order.
