Abstract
A circuit for converting Boolean and arithmetic masks includes 'm' converting units, wherein m is an integer greater than 1. Each of the m converting unit includes; a first converting unit configured to receive first bits of input data, output one of the first bits as a first output bit, perform an XOR operation with respect to at least part of the first bits, and output an XOR operation result as a first intermediate result bit to a next converting unit in a sequence of converting unit ranging between 2 and n−1; and an nconverting unit, wherein n is an integer greater than or equal to 2 and less than or equal to m, configured to receive n−1bits and nbits of the input data, and at least one of an n−1intermediate result bit and n−1output bit from an n−1converting unit, perform an AND operation and the XOR operation with respect to a first group of the received bits, output an operation result for the first group as an noutput bit, perform the AND operation and the XOR operation with respect to a second group of the received bits, and output an operation result of the second group as an nintermediate result bit.
