—We study secure source-coding with causal disclosure , under the Gaussian distribution. The optimality of Gaus-sian auxiliary random variables is shown in various scenarios. We explicitly characterize the tradeoff between the rates of communication and secret key. This tradeoff is the result of a mutual information optimization under Markov constraints. As(More)
—We investigate channel synthesis in a cascade setting where nature provides an iid sequence X n at node 1. Node 1 can send a message at rate R1 to node 2 and node 2 can send a message at rate R2 to node 3. Additionally, all 3 nodes share bits of common randomness at rate R0. We want to generate sequences Y n and Z n along nodes in the cascade such that (X(More)
