Evaluating the Performance of Rijndael Encryption

Abstract

In this paper we present a a comparative analysis of the performance of the Rijndael algorithm, developed with the help of two programming languages, namely C and Matlab. The main goal is to get a full, detailed picture about the functioning of this algorithm. In order to evaluate the performances of the Rijndael algorithm for the two different implementations, we took into account establishing the variable factors within each type of implementation so as to avoid the reasons that might lead to running differences (for instance, the comparison of the two implementations will be performed for the situation in which the encryption key length is the same). We chose to use the traditional algorithm for both types of implementation, in which the input is transformed into 4 blocks of 4 bytes, followed by the handling of each byte from each individual column
