  • Patent number: 8681989
    Abstract: A WCDMA 3G voice communication protection method and a terminal using the method are provided. The method is performed by a terminal operating in conjunction with an S-USIM for voice communication protection. When a calling terminal connects a voice communication channel to a called terminal, secure voice communication is prepared for by collecting information about relevant voice communication. At the calling terminal, synchronous data is set by exchanging the voice communication information with the called terminal, and a secure synchronization procedure is performed based on the set synchronous data. At each of S-USIMs that operate in conjunction with the calling and called terminals, a session key for secure voice communication is generated based on the synchronous data. Secure communication is performed by encrypting and transmitting voice-coded data to be transmitted based on the session key, and decrypting and reproducing received voice-coded data based on the session key.

  • Publication number: 20130156181
    Abstract: 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 sign& 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.
