Enhancing AES with Key Dependent S-Box and Transpose MDS Matrix

Privacy is an important feature in transmission of data. Due to continuous flow data over network, there may be a chance attacks on sensitive data, either passive or active. To provide security, Cryptography plays vital role by scrambling into unreadable form. Several techniques have been developed security for digital transmission. AES one the efficient encryption engaged past decade. There every need improve its mechanism periodically. In this paper we implement Transpose mix column and S-BOX Rotation enhance efficiency. This proposed model provides more Avalanche Effect than traditional AES. Moreover, Diffusion Confusion are crucial Cryptography. The diffusion rate secure shown model. However, S-Box rotation confusion. most efficiently used Wi-Fi, particularly WPA2-PSK(AES), so enhancing needed.
