Abstract: Techniques for fully homomorphic encryption are described. In some examples, a register file to store polynomials is coupled to a butterfly compute path. The butterfly compute path includes a multiplier coupled to a first input and a second input to multiply the first and second input to, when enabled, generate a multiplication output, a first multiplexer coupled to an output of the multiplier and to the first input to output a selection between the output of the multiplier and the first input, an adder to add, when enabled, a third input to the selected output of the first multiplexer, a subtractor to subtract, when enabled, an output of the multiplier from the third input, and a second multiplexer coupled to an output of the multiplier and to the first input to, when enabled, output a selection between the output of the multiplier and the subtractor.
