Abstract: An encryption circuit includes a pipelined encryption core having a plurality of round cores therein. The pipelined encryption core is configured to perform a real round operation on each of a plurality of pieces of input data received therein and generate encryption data from the input data using an encryption operation comprising the real round operation. An encryption controller is provided, which is coupled to the pipelined encryption core. The encryption controller is configured to control the pipelined encryption core so that at least one of the plurality of round cores performs a virtual round operation as part of the encryption operation. The pipelined encryption core is configured to perform a virtual encryption operation using at least one of: (i) dummy data, and (ii) a dummy encryption key.

Abstract: A security device providing a security function for an image, a camera device including the same, and a system on chip (SOC) for controlling the camera device are provided. An image transmitting device may include an image processor configured to process an image to be transmitted to an external device, and a security circuit including a key shared with the external device. The security circuit may be configured to generate a tag used for image authentication by using data of a partial region of the image and the key based on region information for selecting the partial region of the image. The image transmitting device may be configured to transmit the tag, generated to correspond to the image, to the external device with data of the image.

Abstract: An encryption device for performing virtual and real operations and a method of operating the encryption device. The method includes performing a virtual operation; when a real operation request signal is received, determining whether the virtual operation being performed is completed; and in response to the virtual operation being completed, performing a real operation in response to the real operation request signal.

Abstract: Provided are a security processor for performing a remainder operation by using a random number and an operating method of the security processor. The security processor includes a random number generator configured to generate a first random number; a modular calculator configured to generate a first random operand based on first data and the first random number and generate output data through a remainder operation on the first random operand, wherein a result value of the remainder operation on the first input data is identical to a result value of the remainder operation on the first random operand.
