Abstract: The present disclosure relates to methods, devices, and systems for generating a signature of a message by a first device based on a secret key and a public key. The method includes generating a first parameter based on a first multiplication operation on the secret key and a first random number. The method further includes generating a first electronic signature based on the first parameter and the public key. The method further includes generating a second parameter based on the first random number, a second random number, and the message. The method further includes generating a second electronic signature based on the first parameter, the second parameter, the second random number, and the first electronic signature. The method further includes outputting, to a second device, the message, the first electronic signature, and the second electronic signature.

Abstract: According to one embodiment of the present disclosure, an electronic device may include a display and a processor electrically connected to the display. The processor may be configured to classify a frame of content that is being reproduced on the display into a plurality of blocks including at least one pixel, confirm average brightness values of each of the plurality of blocks, determine whether to satisfy at least one specified condition based on the average brightness values of at least some of the plurality of blocks, and adjust brightness of the at least one pixel included in the plurality of blocks if it is determined that the at least one specified condition is satisfied. Other various embodiments may be directed to an electronic device or a method of display content of an electronic device.

Abstract: A display apparatus, an electronic device including the same, and an operating method thereof are disclosed. The display apparatus may include: a window layer configured to contribute to at least one outward appearance of the display apparatus; a pixel layer including at least one pixel configured to display graphic information received from a processor that is functionally connected to the display apparatus, a driving wiring that drives the pixel, and a Black Matrix (BM) disposed in a BM area that does not include the at least one pixel; and a color layer disposed in at least one direction of the pixel layer, and configured to allow a designated color to be exposed to an outside through the window layer when the at least one pixel does not operate, wherein the pixel layer may include: a first substrate including a first plane facing a first direction, and a second plane facing a second direction opposite the first direction; and a pixel electrode, a light-emitter, a cathode, and a second substrate disposed between the first plane of the first substrate and the window layer, and wherein the color layer may be disposed in the BM area.
