Query: A Capacity-achieving One-message Key Agreement With Finite Blocklength
  Analysis   Information-theoretic secret key agreement (SKA) protocols are a fundamental
cryptographic primitive that are used to establish a shared secret key between
two or more parties. In a two-party SKA in source model, Alice and Bob have
samples of two correlated variables, that are partially leaked to Eve, and
their goal is to establish a shared secret key by communicating over a reliable
public channel. Eve must have no information about the established key. In this
paper, we study the problem of one-message secret key agreement where the key
is established by Alice sending a single message to Bob. We propose a
one-message SKA (OM-SKA) protocol, prove that it achieves the one-way secret
key capacity, and derive finite blocklength approximations of the achievable
secret key length. We compare our results with existing OM-SKAs and show the
protocol has a unique combination of desirable properties.
