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.
Claims8
An apparatus for ciphering data in a wireless communication system, the apparatus comprising:
- 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 which comprises 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.
A method of ciphering data in a wireless communication system, the method comprising:
- reading data to be ciphered from a memory, when receiving a cipher command by a cipher hardware;
- ciphering the read data and directly outputting the ciphered data to a transmission data processing unit by the cipher hardware;
- directly receiving the outputted ciphered data, and generating a data packet by adding a header for transmission by the transmission data processing unit;
- and
- directly receiving the generated data packet transmitted from the transmission data processing unit and transmitting the received data packet by an RF communication unit.
