Claim:
1. A method performed by a geolocation update service for altering the status of cryptographic key material, the method comprising: accessing a time since a last geo-location update message was received from a system, the last geo-location update message indicating a previous location of the system; identifying whether the last geo-location update was received within a predetermined length of time; responsive to determining that the last geo-location update message was not received within the predetermined length of time, setting a validity state associated with cryptographic key material previously deployed to the system to a suspended state indicating that the cryptographic key material will not be honored to authenticate the system in an authenticated session; receiving, by a processor via a network, a geo-location update message from the system identifying a current location of the system; accessing a geo-fence attribute set associated with the cryptographic key material, the attribute set comprising geo-fence information that identifies at least one geographic region and a policy that identifies when a status of the cryptographic key material is to be set to either the suspended state where the cryptographic key material will not be honored to validate the system in an authenticated session or a reinstated state where the cryptographic key material will be honored to validate the system in an authenticated session; evaluating the current location of the system relative to the geo-fence information; responsive to the evaluation of the current location and the policy, setting the status of the cryptographic key material to the suspended state when the current location is not in compliance with the policy and setting the status of the cryptographic key material to the reinstated state when the current location is in compliance with the policy.
