    Abstract: A low-profile wideband monopole antenna is provided. The antenna may include a radiating element configured in a bent monopole arrangement to provide a vertical polarization such that an omni-directional radiating characteristic is achieved. The radiating element may include a plurality of slots formed at or edged from each side of the radiating element to increase the effective current path length of the radiating element. The antenna may include a feed and a feeding structure extending from the radiating element to the feed. The antenna may further include a ground plane. The radiating element may be arranged substantially parallel to the ground plane. The surface area of the radiating element may be smaller than the ground plane.

    Abstract: Various embodiments may relate to an optical device. The device may include an elongate substrate, an emitter portion at a distal end portion of the elongate substrate, the emitter portion configured to emit light, and an actuator portion at a proximal end portion of the elongate substrate opposite the distal end portion of the elongate substrate. The emitter portion may include a first electrode, a second electrode, and an active layer between the first electrode and the second electrode so that the light is emitted due to an increase in a temperature of the active layer upon application of a first potential difference between the first electrode and the second electrode. The active layer may be patterned to form a photonic crystal layer for enhancing directionality of the emitted light.

    Abstract: Various embodiments may relate to a memory cell. The memory cell may include a first cell electrode, a first insulator layer and a first magnetic free layer between the first cell electrode and the first insulator layer. The memory cell may also include a second cell electrode, a second insulator layer, and a second magnetic free layer between the second cell electrode and the second insulator layer. A magnetic pinned layer may be between the first insulator layer and the second insulator layer. A direction of magnetization of the first magnetic free layer may be changeable in response to a current flowing between a first end and a second end of the first cell electrode. A direction of magnetization of the second magnetic free layer may be changeable in response to a current flowing between a first end and a second end of the second cell electrode.

    Abstract: There is provided a method of generating a Keccak message authentication code (KMAC) based on white-box implementation, using at least one processor. The method includes: obtaining a white-box implementation of a round function of a KMAC algorithm; receiving an input message; obtaining a plurality of message blocks based on the input message; and for each of the plurality of message blocks at a plurality of iterations, respectively: modifying a current state of the KMAC algorithm based on the message block to produce a modified current state of the KMAC algorithm; inputting the modified current state to a state transformation function including the white-box implementation of the round function; and executing the white-box implementation of the round function based on the modified current state to obtain an updated state of the KMAC algorithm as an output of the state transformation function. In particular, the modified current state inputted to the state transformation function and the updated state outputted from the state transformation function are each white-box protected based on a same set of white-box operations. There is also provided a corresponding system for generating a KMAC based on white-box implementation.
