Analysis of simple inversable functions defined on Galois Fields for cryptography use [articol]

Abstract

The private character of the information transmitted on a communication channel or network could be ensured using some cryptography codes. Different encryption techniques performances depend on the processing time and the complexity of the encoding algorithm. We propose a new and advantageous method for symbol permutation, using inversable algebraic function defined on Galois Fields (GF), which minimizes the necessary memory capacity of the encoding algorithm, ensures a great diversity of data and is harder to attack.
