Claim:
1. A method executed by a system having cryptographic key material used for authenticated communications comprising: storing, by the system in a machine-readable media, a geo-fence attribute set comprising a geo-fence defining at least one geographic region within which the cryptographic key material will be honored for authenticated communications; associating the geo-fence attribute set with the cryptographic key material used for authenticated communications; creating a geo-location update message comprising a current geographic location of the system; and sending the geo-location update message, over a digital network, to a geo-location update service which ascertains whether to change a validity state of the cryptographic key material to suspended when the current geographic location is outside the at least one geographic region and to reinstated when the current geographic location is inside the at least one geographic location and to a default state when the current geographic location is unknown for a period of time.
