Executive Summary

Nowadays the data telecommunication security has been provided by most of well-known stream cipher algorithms which are already implemented in different secure protocols such as GSM, SSL, TLS, WEP, Bluetooth etc. These algorithms are A5/1, A5/2, E0 and RC4. On the other hand, these public algorithms already faced to serious security weakness such that they do not provide enough security of proportional plain data in front of cryptanalysis attacks. In this paper the authors proposed an efficient stream cipher algorithm which generates 23 random bits in each round of processing by parallel random number generator and 115 bits of Initial Vector.
