This paper considers the setup of Alice, Bob and Eve sharing a Gaussian Broadcast channel, and correlated Gaussian sources, assuming these are independent of the channel components. Both secret key generation and secret message transmission are considered. A closed form expression is presented characterizing the optimal trade-off between the secret key and the secret message rates. A few known results are shown to be accepted as special cases
