The development and researching of lightweight pseudorandom number generators

摘要

The paper is devoted to the development and quality assessment of lightweight pseudo-random number generators (PNRG). The design principles of lightweight PRNG (LW-PNRG) are described. The requirements for LW-PNRG quality are formulated. This paper gives an example of the transformation of a classical generator into LW-PNRG by means of modifying the function of feedback (OFB). We propose methods of assessing the quality of pseudo-random numbers formed by lightweight generator. The results of statistical tests of the developed LW-PNRG are also given.
