摘要： A system and method for securing wireless communications are provided. A method for secure communications by a first user includes estimating a channel between the first user and a second user based on a pilot signal transmitted by the second user, determining a first threshold and a second threshold based on the estimate of channel, selecting a first subset of channel estimates, signaling the first subset of channel estimates to the second user, receiving a second subset of channel estimates from the second user, for each channel estimate in the second subset of channel estimates, quantizing the channel estimate based on a relationship between a gain of the channel estimate and the first threshold and the second threshold, generating a first secret key based on quantized channel estimates, verifying that the first secret key matches a second secret key generated by the second user, and transmitting information to the second user.

摘要： A system and method for securing wireless communications are provided. A method for secure communications by a first user includes estimating a channel between the first user and a second user, thereby producing an first phase estimate of the channel, generating a first block of secret bits based on the first phase estimate of the channel, and transmitting public information regarding the first block of secret bits to the second user. The second user makes use of the public information to generate a second block of secret bits.

摘要： A system and method for securing wireless transmissions is provided. A method for transmitting secure messages by a transmitter includes encoding a message with a secrecy code to produce L output codewords, where L is an integer value greater than one. The secrecy code includes a first security code and a second security code. The method also includes transmitting one of the L output codewords to a communications device when a channel quality of a channel between the transmitter and the communications device satisfies a criterion, and repeating the transmitting for any remaining L−1 output codewords.
