Current differential logic gate, preferably for the cryptograhic systems resistant to attacks, with the side channel

摘要

logical gate.in which, depending on the direction and the amplitude of the input current flowing between the input gate (1w) and clips (2w), the voltage at the receiver (ow) controls the two systems ru00f3u017cnicowymi (r1) and (r2)driven respectively by two source current (i1) and (i2).differential systems, by combining them with any conductive elements (pa) and (pb) and blocking circuits (b1) and (b2) are, or not, to output currents sources appropriate clamps.by fusing appropriate pairs of output terminals, it is possible that one of the four transition pru0105dowych.the gate may have a continuous first clamp output 'a' (2a) with a second clamp output 'a' (2a) and a first clamp output b (1b) with the second clamp output b (2b).and can have continuous first clamp output 'a' (1a) of the first clamp the output b (1b) and the second clamp output 'a' (2a) with a second clamp output b (2b).
