  • System and method for enabling a scalable public-key infrastructure on a smart grid network
    Patent number: 10764261
    Abstract: 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.
