Abstract

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 previous protocols fail.
