Testing of pseudorandom signal generators based on the Lorentz system

This work presents results of the testing of modi ed pseudorandom signal generators. Two generators developed on the basis of the Lorentz system with chaotic dynamics are considered. The rst generator is described by the Lorentz system implemented over a Galois eld, and the second is described by the Lorentz system in which digital sequence formation occurs by periodic sampling from signal signatures. As an additional con rmation of the relevance of the results obtained, the article valuates a generator developed on the basis of the standard Matlab function for binary random sequence generating. Generator testing was carried out using a test battery developed by the National Institute of Standards and Technology, which includes 15 di erent tests. The results obtained are compared with the results obtained by testing reference generators. The results of this research can be applied in the development of cryptographic and data transmission systems.
