This document defines extensions to the Kerberos protocol specification [1] to provide a method for using public key cryptography to enable cross-realm authentication. The methods defined here specify the way in which message exchanges are to be used to transport cross-realm secret keys protected by encryption under public keys certified as belonging to KDCs.
