Modified Advanced Encryption Standard algorithm for fast transmitted data protection

With the exponential growth of digital data exchange over the computer network in recent times, protection of information content is becoming a major concern. There are many security risks, which can easily compromise the data transmitted over the network. Cryptography plays an important role in ensuring the security of digital data transmission over these unsafe networks,so in order to ensure secure and fast data transmitted over the network, an enhanced modification for Advanced Encryption Standard (AES) algorithm is proposed and implemented using additional key which generated using linear feedback shift register(LFSR), which provide an efficient technique to pseudo random number generation,also rounds number are decreased . The proposed method give promised result comparing with original AES algorithm result for different data type text, image, and video.
