Secret Key Agreement from Correlated Gaussian Sources by Rate Limited Public Communication
نویسندگان
چکیده
We investigate the secret key agreement from correlated 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 a closed form expression of the optimal trade-off between the rate of key generation and the rate of the public communication. Our results clarify an essential difference between the key agreement from discrete sources and that from continuous sources. key words: Bin Coding, Gaussian Sources, Privacy Amplification, Quantization, Rate Limited Public Communication, Secret Key Agreement

Compressed Secret Key Agreement: Maximizing Multivariate Mutual Information per Bit
The multiterminal secret key agreement problem by public discussion is formulated with an additional source compression step where, prior to the public discussion phase, users independently compress their private sources to filter out strongly correlated components in order to generate a common secret key. The objective is to maximize the achievable key rate as a function of the joint entropy o...
متن کاملStrong Secrecy in Pairwise Key Agreement over a Generalized Multiple Access Channel
This paper considers the problem of pairwise key agreement without public communication between three users connected through a generalized multiple access channel (MAC). While two users control the channel inputs, all three users observe noisy outputs from the channel and each pair of users wishes to agree on a secret key hidden from the remaining user. We first develop a “pre-generated” key-a...
متن کاملOptimal SVD-based Precoding for Secret Key Extraction from Correlated OFDM Sub-Channels
Secret key extraction is a crucial issue in physical layer security and a less complex and, at the same time, a more robust scheme for the next generation of 5G and beyond. Unlike previous works on this topic, in which Orthogonal Frequency Division Multiplexing (OFDM) sub-channels were considered to be independent, the effect of correlation between sub-channels on the secret key rate is address...
متن کاملSecret-key agreement over unauthenticated public channels I: Definitions and a completeness result
This is the first part of a three-part paper on secret-key agreement secure against active adversaries. In all three parts, we address the question whether two parties, knowing some correlated pieces of information X and Y , respectively, can generate a string S about which an adversary, knowing some information Z and having read and write access to the communication channel used by the legitim...
