Secret Key Agreement from Vector Gaussian Sources by Rate Limited Public CommunicationSecret Key Agreement • December 8th, 2024
Abstract—We investigate the secret key agreement from corre- lated vector Gaussian sources in which the legitimate parties can use the public communication with limited rate. For the class of protocols with the one-way public communication, we show that the optimal trade-off between the rate of key generation and the rate of the public communication is characterized as an optimization problem of a Gaussian random variable. The characterization is derived by using the enhancement technique introduced by Weingarten et. al. for MIMO Gaussian broadcast channel.
