Abstract
An apparatus for ciphering data in a wireless communication system. The apparatus includes a memory which stores data to be ciphered; a controller which outputs a cipher command for each layer of a wireless protocol; a protocol processing unit including a cipher hardware, which receives the cipher command outputted from the controller, reads data to be ciphered from the memory, ciphers the data and outputs the ciphered data, and a transmission data processing unit, which receives ciphered data that is directly outputted from the cipher hardware, adds a header for transmission and generates a data packet; and an RF communication unit which directly receives the generated data packet and transmits the received data packet.
