PCT No. PCT/SE93/00414 Sec. 371 Date Jan. 11, 1994 Sec. 102(e) Date Jan. 11, 1994 PCT Filed May 11, 1993 PCT Pub. No. WO93/23804 PCT Pub. Date Nov. 25, 1993.An apparatus and a method for random number generation. The apparatus includes a feedback shift register which receives signals from a first signalling device, the shift register further being connected to a t least one delay device. This or these delay device(s) deliver (each) a random number when receiving a clock signal from a second sigalling device. The first signalling device includes a fast clock and the feedback shift register is connected to the delay device(s) via at least one logical gate, the output(s) of delay device(s) being fed back to the gate(s), the second signalling device delivering clock signals originating from external events. |
