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 alerting method for portable electronic devices, the alerting method being performed by at least one of first and second portable devices. The method includes first and second electronic devices communicating with one another through two different wireless channels, the first channel providing longer range communications than the second channel. The second electronic device may enter an alarm mode of operation if communications through a channel fails. The second electronic device may exit the alarm mode of operation if communications through the other channel are restored.

Abstract: Disclosed is a system for recognizing a user location using sensor-based activity recognition. The system includes a mobile device which includes a sensor module configured to sense information about at least one of a user state and surrounding environments, a first processor configured to extract activity information based on the sensed information, and a first communication module configured to transmit the extracted activity information; and a user terminal device which includes a second communication module configured to receive the activity information from the first communication module, and a processor configured to determine a user location in a user space corresponding to a user activity based on the received activity information. By determining a user's location in a user space corresponding to a user activity, it is possible to control electronic devices corresponding to the user activity or provide a service of monitoring activities of the old and weak and the child.
