Abstract
A crypto processor, a method of operating a crypto processor, and an electronic device including a crypto processor. A method of operating a crypto processor for performing a polynomial multiplication of lattice-based texts includes transferring coefficients of polynomials for the polynomial multiplication to multipliers, performing multiplications for a portion of the coefficients in parallel using the multipliers, performing an addition for a portion of results of the multiplications using an adder, and determining a result of the polynomial multiplication based on another portion of the results of the multiplications and a result of the addition.
