We consider perfect secret key generation for a “pairwise independent network” model in which every pair of terminals share a random binary string, with the strings shared by distinct terminal pairs being mutually independent. The terminals are then allowed to communicate interactively over a public noiseless channel of unlimited capacity. All the terminals as well as an eavesdropper observe this...

In this survey presentation, we consider Shannon-theoretic secret key generation by multiple parties for two categories of models. In the first category, termed source models, multiple terminals are provided prior and privileged access to correlated signals. In the second category, called channel models, these terminals are connected by a secure noisy channel with multiple input and outputs. In both...
