摘要： A secret key generation apparatus and method are provided. The secret key generation apparatus includes at least one antenna, amplification/phase controllers, a transceiver, and a random signal controller. The antenna receives a wireless signal from a counterpart terminal that performs wireless communication. The amplification/phase controllers control the amplification gain and phase of the wireless signal that is received via at least one antenna. The transceiver measures the status of a wireless channel using the wireless signal having the controlled amplification gain and phase, determines parameters based on results of the measurement, and generates a secret key based on results of the determination. The random signal controller controls the amplification/phase controllers so that the amplification gain and phase are adjusted whenever the transceiver generates a secret key.

摘要： An apparatus and method for generating a group key using the status of a wireless channel are provided. The apparatus includes a representative channel response selection unit for selecting a representative channel response signal from among pilot signals received from slave terminals. A key generation unit generates a group key based on a representative channel response value of the representative channel response signal. A hash value generation unit generates a hash value corresponding to the group key. A transmission pilot control unit adjusts power intensities of transmission pilots of the respective slave terminals using the channel response value of the representative channel response signal and channel response values and transmission power intensities of the slave terminals. A communication unit is individually connected to the slave terminals and configured to transmit pilot signals, power intensities of which have been adjusted, and the hash value to the slave terminals.
