Abstract: in this paper, the great overview of modern foreign and domestic literature are shown; this overview describes cryptographic protection of information and in particular systems of stream generation of pseudorandom sequences. The results of international projects and competitions in the sphere of design of stream encryption systems such as NESSIE, CRYPTREC, eSTREAM are studied. The steady trend to applying of nonlinear feedback shift registers in stream algorithms are shown. Their dignities and disadvantages are analyzed, the examples of their implementations are shown.
Keywords: information protection, cryptography, stream cipher, pseudorandom sequences, encryption algorithm, nonlinear feedback shift registers, NLFSR
