Abstract
In this article, using a 128-bit key, 264 A stream coding algorithm has been developed that is easy to implement in software, allowing random bit sequences to be generated up to the bit length, i.e. the key stream. This algorithm is similar to and simpler than the RC4 algorithm, which retains its security, speed, and flexibility features without using an initialization vector. The pseudorandom sequences generated by this algorithm meet National Institute of Standards and Technology (NIST) requirements for randomness.
