A method and system for encrypting data in a wireless communication system are provided. The system includes a first node for generating a first encryption key using a plurality of encryption key parameters when performing authentication with a second node, for changing a second parameter among the plurality of encryption key parameters to generate a second encryption key being identical to the first encryption key, if a first parameter among the plurality of encryption key parameters is changed during re-authentication between the first node and the second node, for generating the second encryption key using the changed first parameter and the changed second parameter, and for encrypting data to be transmitted to the second node using the second encryption key.

Method and system for encrypting data in a wireless communication system

A complex terminal includes an apparatus for controlling a Universal IC Card (UICC). The apparatus is configured to obtain a control information through a UICC initialization and provide a corresponding communication modem with the control information. A communication modem can request a communication authority based on the control information and obtain the communication authority from a controller. A selector can connect the corresponding communication modem to the UICC while the controller provides the corresponding communication modem with the communication authority.

An LCD is manufactured to provide a wide viewing angle device and may reduce manufacturing costs according to an embodiment. The LCD includes a substrate, a gate line disposed on the substrate, a gate insulating layer disposed on the gate line, a semiconductor layer disposed on the gate insulating layer, a data line contacting the semiconductor layer, a drain electrode contacting the semiconductor layer and separated from the data line, a pixel electrode contacting the drain electrode, a passivation layer disposed on the pixel electrode, and a common electrode disposed on the passivation layer and including a branch electrode overlapping the pixel electrode. In one embodiment, the pixel electrode contacts an end portion of a thin film transistor. The LCD manufacturing process may be shortened and may save manufacturing costs because the LCD process need not make contact holes to connect the pixel electrode and the TFT.

Liquid crystal display and method of manufacturing the same

A liquid crystal display ('LCD') capable of improving display quality includes a first insulating substrate, gate wiring lines formed on the first insulating substrate and extending in a first direction, pixel electrodes, each of which includes first and second sub-pixel electrodes that are, respectively, applied with different data voltages from first and second wiring lines insulated from and crossing the gate wiring lines, extending in a second direction and an insulting layer interposed between the first data wiring line and the second data wiring line overlapped by the first data wiring line. Therefore, an aperture ratio of the LCD increase because the first data wiring line overlapped the second data wiring line have less area between pixel electrodes. A display quality of the LCD improves.
