T. D. B. Weerasinghe . Analysis of a Modified RC4 Algorithm. International Journal of Computer Applications. 51, 22 ( August 2012), 12-16. DOI=10.5120/8341-1617
In this paper, analysis of a simply modified RC4 algorithm is presented. RC4 is the most widely used stream cipher and it is not considered as a cipher that is strong in security. Many alternatives have been proposed to improve RC4 key generation and pseudo random number generation but the thoughts behind this work is to try out a simple modification of RC4's PRGA, where we can mention like this:
