Abstract
A system for generating and applying a secure token in a resource distribution network is provided. For example, a headend system generates a global token based on a time duration specified for multiple meters that are in communication with the headend system through at least a mesh network in a normal condition. The global token is associated with the time duration and is applicable to the multiple meters. The headend system causes the global token to be broadcast via a broadcast network. After receiving the global token, the meter verifies the global token and determines the time duration associated with the global token. The meter further connects premises associated with the meter to a resource distribution network for at least the time duration associated with the global token.
