DBST: A lightweight block cipher based on dynamic S-box

Block ciphers, a branch of modern cryptography, are playing a more prominent role in protecting information security as 5G technology develops. Although encryption algorithms of the traditional Feistel structure have great advantages in terms of consistent encryption and decryption, they have poor diffusion effects.
