Researches of periodic properties of sequences of pseudocasual numbers which are formed the generator of RC4 are inprocess conducted. The conducted researches rotined that the considered generator owned the "weak" keys the use of which leads to forming of sequences of pseudocasual numbers with a small period, that, in same queue, can result in successful cryptographic attacks.
