Abstract :
In this paper a personalized version of the Rijndael algorithm is analyzed (i.e. namely, from ASCII characters frequencies and ciphertext correlations point of view). The aforementioned personalization consists in pseudo-randomly modifying ShiftRows & MixColumns transformations, using two multiply-with-carry PRNGs designed by George Marsaglia.
