Abstract
This paper introduces the public Eve scenario and shows that the secret key rate in this scenario is bounded by the intrinsic information. This elucidates previous results and gives new insights in the gap between formation and extraction of secret information. Intrinsic information, in its function as an upper bound on the secret key rate, is generalized to secret key agreement from arbitrary tripartite quantum states.
