Claim 13:
14. 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) response 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 resource, the action identifier of the selected trust rule corresponds to a response in the ICN response message, and the target identifier of the selected trust rule corresponds to an electrical infrastructure user;
publishing, on a communication channel, the ICN response message, wherein the publication of the ICN response message causes an enforcement computing system, on the communication channel and associated with the electrical infrastructure user, 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 resource, wherein the certificate includes an electrical infrastructure resource name defined in an ICN hierarchical namespace and an electrical infrastructure resource public key; and
wherein the enforcement computing system associated with the electrical infrastructure user, in response to subscribing to the ICN response message, the ICN response message including the electrical infrastructure resource name defined in the ICN hierarchical namespace:
determines, from the ICN response message, the target identifier and the action identifier of the ICN response message, wherein the target identifier of the ICN response message corresponds to the electrical infrastructure user; and
determines whether the electrical infrastructure resource, associated with the electrical infrastructure resource name, is authorized to respond, corresponding to the action identifier of the ICN response message, to the electrical infrastructure user, based on the maintained authorization information.
