Modified Advanced Encryption Standard algorithm for fast transmitted data protection

Abstract

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.

A Secure Environment Using a New Lightweight AES Encryption Algorithm for E-Commerce Websites

“…In this paper, the AES has not modified itself, but the technique of generating the encryption key is changed depending on the flower pollination algorithm, which consumes additional time and increases only the S-Box complexity, not the entire algorithm. Another study by [44] proposed and implemented an enhanced modification for the advanced encryption standard (AES) algorithm using an additional key generated using a linear feedback shift register (LFSR), which provides an efficient technique for pseudorandom number generation, as well as a reduction in the number of rounds. e algorithm complexity depends on key generation using LFSR.…”

Implementasi Algoritma AES untuk Keamanan Data Rekam Medis

“…Enkripsi AES (Advanced Encryption Standard) sendiri merupakan satu dari beberapa teknik kriptografi yang dimanfaatkan guna mengatasi keamanan data dengan cara mengenskrip data sehingga tidak memngetahui key pada dokumen tidak bisa membuka dokumen tersebut [10]. AES sendiri merupakan algoritma perkembangan dari algoritma DES, dimana jika keduanya dibandingkan AES sendiri memerlukan waktu yang jauh lebih singkat ketika melakukan enkripsi dan dekripsi [11].…”
