The modernization of generators of scale of existing algorithm of enciphering А5 of the standard GSM was offered. The received variants of modernization of algorithm А5 are investigated under some tests of research pseudo-casual sequences (PCS). The carried out comparative analysis with the help of the tests for research PCS of the offered modernizations of algorithm А5 has shown, that at increase of the periods LFSR the resulting period of scale is increased them least general multiple and, hence. It results in increase cryptographic stability of algorithm А5
