The Intrinsic Conditional Mutual Information and Perfect Secrecy

Ueli Maurer and Stefan Wolf

IEEE International Symposium on Information Theory — ISIT '97, IEEE, pp. 88, Jun 1997.

Conditions are derived for the possibility and impossibility of information-theoretic secret-key agreement by public discussion. A new quantity, the intrinsic information, is introduced and its relationship to secret-key agreement is investigated. A new protocol is described that allows secret-key agreement in situations for which the previous protocols fail.
