 abstract = {We characterize the secret message capacity of a wiretapped erasure channel where causal channel state information of the honest nodes is publicly available. In doing so, we establish an intimate connection between message secrecy and secret key generation for the same channel setup. We propose a linear coding scheme that has polynomial encoding/decoding complexity, and prove a converse that shows the optimality of our scheme. Our work also demonstrates the value of causal public feedback, which has previously been shown for the secret key generation problem.},
