Fast software encryption system based on local pseudorandomness

Abstract

New software-oriented single key cryptosystem based on local pseudorandomness is considered. Its cryptorobustness is characterized in probabilistic terms. The minimal size of the known (chosen) plaintext has been estimated to be >3·1031(>1021) bytes the cryptorobustness being >1057 (>1037) operations.
