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.

摘要： A method for recovering a frame erasure at a voice over internet protocol (VoIP) environment is provided. The method includes: extracting coder parameters of received packets; if an erased packet exists during the extracting of the coder parameters, regenerating speech characteristic parameters of the erased packet by referencing a vector quantization codebook index interpolation table (VCIIT) formulated based on representative values of speech characteristic parameters reflecting auditory recognition characteristics and performing a linear interpolation on speech characteristic parameters of the normally received packets allocated previous and future of the erased packet; and recovering the erased packet by combining the regenerated speech characteristic parameters. The proposed frame erasure recovery method can minimize an additional delay and increases in bandwidth and computation and improve a capability of recovering the erasure. Also, the frame erasure recovery method can be easily implemented to a VoIP system.
