摘要
The present invention relates to a regression analysis arithmetic apparatus for data encrypted by a fully homomorphic encryption method, comprising: a communication module for transmitting and receiving encrypted data; a memory in which an operation program is stored; and a processor executing the arithmetic program. The operation program consists of XOR operation logic, XNOR operation logic, AND operation logic, OR operation logic, complement operation logic, absolute value operation logic, right movement operation logic, left movement operation logic, MUX operation logic, case comparison operation logic for homomorphic cipher data. , including addition logic, subtraction logic, absolute value logic, multiplication logic, division logic, and exponential function logic. In addition, the operation program includes a sigmoid function logic for performing a sigmoid function operation, wherein the sigmoid function logic outputs the two's complement by inputting the input homomorphic encryption data to the complement operation logic, The output of the complement operation logic is input to the exponential function logic, the first encrypted value encrypted with '1' bit and the output of the exponential function logic are input to the addition logic, and the first encrypted value is the dividend (Q) As , the output of the addition logic is input to the division logic as a divisor (M), and the output of the division logic is returned.
