Half adder is a combinational circuit that performs simple addition of two binary numbers. The input variables designate the augend and addend bits; the output variables produce the sum and carry. It ...

Subtractor circuits take two binary numbers as input and subtract one binary number input from the other binary number input. Similar to adders, it gives out two outputs, difference and borrow ...

Logic encryption for combinational circuits are proposed in this paper. Logic encryption is achieved by using key gate transistors in the circuit schematic of subtractors and adders. In this work, two ...
