RC4OK. An improvement of the RC4 stream cipher

Authors: Khovayko O., Schelkunov D.


In this paper we present an improved version of the classical RC4 stream cipher. The improvements allow to build lightweight high-performance cryptographically strong random number generator suitable for use in IoT and as a corresponding component of operating systems. The criterion for high performance is both a high speed of generating a stream of random numbers and low overhead costs for adding entropy from physical events to the state of the generator.
