Abstract: A security device includes a secure processor, a mail box, a cryptographic intellectual property (IP), a secure direct memory access (DMA) circuit, and an internal memory. The secure processor provides an isolated execution environment. The mail box transfers a request from a CPU to the secure processor. The cryptographic IP performs one or more secure operations, including a signature certification operation, an encryption/decryption operation, and an integrity verification operation, on secure data within the isolated execution environment and without intervention of the CPU. The secure DMA circuit controls the one or more secure operations within the isolated execution environment, wherein only the secure processor is configured to control the secure DMA circuit. The internal memory stores the secure data on which the one or more secure operations are performed. The cryptographic IP includes a DMA circuit configured to control data access to an external storage.

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.

Abstract: A device system that performs group authentication and an operating method thereof are provided. The device system includes multiple devices. The operating method of the device system includes performing a first authentication procedure with respect to a first device that is newly connected to the device system; and performing a second authentication procedure with respect to the first device via an authentication group including at least two devices selected from the devices. The second authentication procedure is a group-based authentication procedure. If the first and second authentication procedures are successful, the operating method includes approving connection of the first device to the device system.
