Abstract

There is provided a device for processing homomorphically encrypted data. The device includes: inter-line butterfly array blocks, each inter-line butterfly array block including inter-line modulus butterfly units, each inter-line modulus butterfly unit being configured to perform a modulus butterfly operation based on a computation pair of data points received corresponding to a pair of input data points at a same row of a matrix of input data points; intra-line butterfly array blocks, each intra-line butterfly array block including intra-line modulus butterfly units, each intra-line modulus butterfly unit being configured to perform a modulus butterfly operation based on a computation pair of data points received corresponding to a pair of input data points at a same column of the matrix of input data points; and a clock counter communicatively coupled to each inter-line butterfly array block and each intra-line butterfly array block, and configured to output a counter signal.
