|+||Abstract: A security measure is introduced that is based on informational divergence and that includes strong secrecy and stealth communication. The measure is applied to wire-tap channels and it is shown how the capacity region relates to Wyner's secrecy region. The converse follows by a short proof that uses a telescoping identity. The coding theorem is established by using a simple proof whose key step is applying Jensen's inequality to the logarithm, as well as a few typicality arguments. An operational meaning for stealth follows, in the usual way, by using binary hypothesis testing. The talk is based on joint work with Jie Hou from TUM.|
