SYSTEM AND METHOD FOR ENABLING A SCALABLE PUBLIC-KEY INFRASTRUCTURE ON A SMART GRID NETWORK

摘要

A method for enabling a scalable public-key infrastructure (PKI) comprises invoking a process of receiving a message for a device, identifying an association ID for the device, retrieving encrypted association keys stored on the server for communicating with the device, the encrypted association keys encrypted using a wrapping key stored on a Hardware Security Module (HSM). The method further comprises sending the message and the encrypted association keys to the HSM, unwrapping, by the HSM, the encrypted association keys to create unwrapped association keys, cryptographically processing the message to generate a processed message, deleting the unwrapped association keys, sending the processed message to the device, and invoking, concurrently and by a second application, the process.

1. A method for enabling a scalable public-key infrastructure (PKI), comprising:
invoking, by a first application, a process comprising:
receiving, by a server, a message for a device;identifying, by the server, an association ID for the device;retrieving, by the server and using the association ID, a plurality of encrypted association keys stored on the server for communicating with the device, wherein the plurality of encrypted association keys are encrypted using a wrapping key stored on a Hardware Security Module (HSM);sending the message and the plurality of encrypted association keys to the HSM;unwrapping, by the HSM and using the wrapping key, the plurality of encrypted association keys to create unwrapped association keys;cryptographically processing, by the HSM and using the unwrapped association keys, the message to generate a processed message;deleting the unwrapped association keys;sending the processed message to the device; and invoking, by a second application, the process, wherein the first application and the second application invoke the process concurrently.
