Design of novel SMS4-BSK encryption transmission system

In our day-to-day life, securing the confidential data and communicating the same to the authorized receiver are the biggest challenges. In Defense, Medical and Banking domains, the security over wireless medium should be high. SMS4-BSK is designed to provide a faster encryption with the required security over Wireless Local Area Network (WLAN). A novel SMS4-BSK architecture is proposed in this paper. The new design is implemented in Kintex 7 FPGA and it is proved that the new architecture can perform encryption and decryption faster than the existing SMS4 architectures. The proposed cryptosystem is capable of resisting cryptanalysis over Ciphertext-only attack, Known-plaintext attack, Chosen-plaintext attack, and Chosen-ciphertext attack. Finally, the possible ways of changes that can be made for improving speed are discussed.
