Abstract: An application processor includes a security processor. An operating method of the security processor includes generating a recoder input including a digit-unit multiplier and a reference bit. At least one random bits having a random value are generated. When the recoder input has a predetermined pattern, the recoder input is converted into a first recoding value or a second recoding value according to a random bit corresponding to the recoder input to generate a recoding result.

Abstract: An electronic multiplier, such as a multiplication circuit, may include a partial product generator, a Booth code encoder and an accumulator. The partial product generator may generate partial product data based on a Booth code and multiplicand data. The Booth code encoder may generate the Booth code based on multiplier data. The Booth code may include a zero-generation Booth code and a zero-avoidance Booth code. The Booth code encoder may selectively generate the zero-generation Booth code or the zero-avoidance Booth code when the partial product data correspond to a partial product of zero. The accumulator accumulates the partial product data to provide a multiplication result of the multiplicand data and the multiplier data.
