The invention discloses a data encryption method, a data encryption chip, a data encryption device, computer equipment and a nonvolatile computer readable storage medium. The data encryption method comprises the steps that a modulus and a modulus to be taken in the encryption process are obtained, the modulus is the sum of a first product of a first parameter and a second parameter and a third parameter, the first parameter is the d power of 2, d is an integer, and the modulus to be taken is a binary integer; performing modulo operation on the to-be-taken modulus according to the first product, and converting division operation on the first parameter into shift operation in the modulo operation to obtain a quotient; calculating a first remainder of the to-be-fetched modulus relative to the first product according to the quotient value; and according to the first remainder, the quotient value and a third parameter, calculating a second remainder of the to-be-taken modulus relative to the modulus to determine a
