Maximum Period Pseudo-Random Number Generator Filter Based on Hash Function

The development of information technologies allows to significantly increase the efficiency of processing, transmission and storage of information, especially in critical control systems. At the same time, a significant increase in the volume of processed and transmitted data, the development of modern countermeasures puts forward increased requirements for information security. An effective mechanism for protecting information is modern means of cryptographic transformation, including promising methods for generating pseudo-random sequences, which are used as the main component of cryptographic protection subsystems against unauthorized access to automated data processing.
