Claim 0:
1. A method, performed by a computing system, to secure access to networked electrical infrastructure, the method comprising:
maintaining, at the computing system, a trust policy comprised of a plurality of trust rules, wherein each trust rule comprises an origin identifier, a target identifier, and an action identifier;
generating an Information Centric Networking (ICN) command message based on a trust rule selected from the plurality of trust rules, wherein the origin identifier of the selected trust rule corresponds to an electrical infrastructure user, the action identifier of the selected trust rule corresponds to a command in the ICN command message, and the target identifier of the selected trust rule corresponds to an electrical infrastructure resource;
publishing, on a communication channel, the ICN command message, wherein the publication of the ICN command message causes an enforcement computing system, on the communication channel and associated with the electrical infrastructure resource, to maintain authorization information characterized by the origin identifier, target identifier, and action identifier of the selected trust rule;
cryptographically signing a certificate associated with the electrical infrastructure user, wherein the certificate includes an electrical infrastructure user name defined in an ICN hierarchical namespace and an electrical infrastructure user public key; and
wherein the enforcement computing system associated with the electrical infrastructure resource, in response to subscribing to the ICN command message, the ICN command message including the electrical infrastructure user name defined in the ICN hierarchical namespace:
determines, from the ICN command message, the target identifier and the action identifier of the ICN command message, wherein the target identifier of the ICN command message corresponds to the electrical infrastructure resource; and
determines whether the electrical infrastructure user, associated with the electrical infrastructure user name, is authorized to perform an action, corresponding to the action identifier of the ICN command message, on the electrical infrastructure resource, based on the maintained authorization information.
