ePrint Report: RC4OK. An improvement of the RC4 stream cipher

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 …
