System and method for an extended web of trust
First Claim
1. An industrial automation gateway providing an extended web of trust comprising:
- a cloud communication interface coupled with, and configured for communication with, a cloud automation facility, the cloud automation facility comprising a cloud hardware memory storing a cloud root certificate from a first root certificate authority and a subordinate certificate;
a hardware memory storing a gateway root certificate from a second root certificate authority and the subordinate certificate; and
a processor coupled with the cloud communication interface and the hardware memory, configured to;
determine if the subordinate certificate has been certified by the first root certificate authority and the second root certificate authority; and
transfer automation data to the cloud automation facility using the subordinate certificate only if the subordinate certificate has been certified by both the first root certificate authority and the second root certificate authority.

Abstract
An industrial automation gateway providing an extended web of trust is provided. The industrial automation gateway includes a cloud communication interface coupled with a cloud automation facility, a hardware memory, and a processor coupled with the cloud communication interface and the hardware memory. The cloud automation facility includes a cloud hardware memory storing a cloud root certificate from a first root certificate authority and a subordinate certificate. The hardware memory stores a gateway root certificate from a second root certificate authority and the subordinate certificate. The processor is configured to determine if the subordinate certificate has been certified by the first root certificate authority and the second root certificate authority. The processor is also configured to transfer automation data to the cloud automation facility using the subordinate certificate only if the subordinate certificate has been certified by the first root certificate authority and the second root certificate authority.
