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

Original language description

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.
