Annotations languages:

Approach development to creation of systems of stream encryption of the data based on a principle of a diversity, with use of cryptographic keyless hash functions is offered. The general structural schema of offered diverse system is described, also options of creation of encoding stages structures, used for formation of pseudorandom sequence are offered. Principles of a choice of a method of encoding for each unit of the input message are described. Also features of an approach to implementation of this system on the basis of technology of FPGA technology are considered here.
