SNOW3G Modified by using PLL Algorithms in Magic Cube

Thomas and Patrik are working on a stream cipher called SNOW 3G. In 2006, it was chosen as the centerpiece of new set confidentiality integrity algorithms for Universal Mobile Telecommunications System (UMTS). 2008, Böhm published an article named "Statistical Evaluation Stream Cipher 3G." He put randomness 3G key generator to test. As test tool, uses NIST statistics package, which consists three kinds tests: lengthy data, short initialization vector data. Only data failed eight random chance results out tests, according report's findings. The suggestions, he claims, fail due flaw with in cipher's initialization. this paper, we use PLL algorithm modify generation keystream. We employ same itself employed. exceed whole statistic exam experiment. findings show that has effect randomness. Index Terms— SNOW-3G, Cipher, Algorithms.
