Apparatus and method for transmitting secure data in wireless communication system

摘要

An apparatus and method for transmitting secure data in a wireless communication system are disclosed. The apparatus includes a key generation unit, and a transmission and reception unit. The key generation unit generates an encryption key stream that is used to convert plain text data into an encrypted data signal. The transmission and reception unit obtains wireless channel state information from a received pilot signal and transmits the obtained wireless channel state information to the key generation unit, and encrypts the plain text data based on the encryption key stream and transmits the encrypted plain text data to a counterpart terminal over a wireless channel. The key generation unit generates the encryption key stream based on the wireless channel state information, and transmits the encryption key stream to the transmission and reception unit.
