Its power supply logic is connected with pulse keying logic. Its keying reset logic is connected with pseudo-random control logic and keying latch and decode logic. Its cipher set-up bus is connected with keying latch and decode logic and comprehesive control logic connected to lock body. Its advantages are firm structure and "cipher trap" and "psdudo-random mechanism" measures.
