Improvement of CPRNG of the PM-DC-LM Mode and Comparison with its Previous Version

Popis výsledku v původním jazyce

This paper presents the last results from our research focused on proposing the polymorphous mode of operation of block ciphers. The first attempt was based on Chaotic Pseudo-Random Number Generator (CPRNG) using logistic maps and it is called Polymorphous Mode - Deterministic Chaos - Logistic Maps mode (PM-DC-LM). CPRNG controls the polymorphous behavior of this mode. The CPRNG returns two values, g and d. Value g represents the last three digits of the number generated by CPRNG and the value d represents the last digit. Based on these two values, function F is controlled. In the initially proposed actual version, the CPRNG was limited in generating values ending by digits from one to nine. Thus, this leads to a non-optimal probabilistic distribution of values g and d. Therefore, an improvement is necessary. This paper shows the principle for improving the CPRNG in the PM-DC-LM mode and how to ensure the whole interval of values for g and d is generated, including numbers ending with zero. The principle is applied on the CPRNG and then it is tested. The differences between the actual and the upgraded version of the PM-DC-LM are described using the probabilistic distribution of generated values g and d. The entropies for values g and d of actual and upgraded versions are also calculated. These calculations are based on one million samples of values g and d.
