Effective Secrecy: Reliability, Confusion and Stealth

If you have a question about this talk, please contact Jossy Sayir .

Effective secrecy is an information-theoretic security measure that includes strong secrecy and stealth communication. Effective secrecy is applied to the wire-tap channel and it is shown that the capacity region is the same as for strong secrecy. The converse follows by a new and simplified proof that uses a telescoping identity. The coding theorem is established by using a recent proof for obtaining resolvability limits. We develop an operational meaning for stealth by using binary hypothesis testing.

This is joint work with Jie Hou from TUM .
