Abstract
Disclosed herein are systems and methods that use blockchain technology to protect power system data. For example, a receiving device may receive a smart contract. The receiving device may obtain the encrypted power system measurements from the smart contract via distributed ledger. The receiving device may decrypt the power system measurements from the smart contract using a private key of the receiving device. The receiving device may display the decrypted power system measurements on a display of the receiving device.
Claims15
A sending device, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, wherein the one or more processors are configured to:
- obtain a power system measurement of an operating characteristic of a power system during operation;
- encrypt the power system measurement with a public key of a designated receiving device;
- load the encrypted power system measurement into a smart contract to store the power system measurement;
- and
- send the smart contract to a pre-defined address of the designated receiving device, built into the smart contract during commissioning of the sending device prior to obtaining the power system measurement, to cause the smart contract to be inserted onto a distributed ledger to prevent modification of the power system measurement and to allow the designated receiving device to decrypt the encrypted power system data using a private key, corresponding to the public key of the designated receiving device.
A receiving device, comprising:
- a memory;
- and
- one or more processors operatively coupled to the memory, wherein the one or more processors are configured to:
- receiving, from a sending device, a smart contract having an encrypted power system measurement during operation that is encrypted with a public key of the receiving device, wherein the smart contract has a pre-defined address of the receiving device built into the smart contract during commissioning of the sending device prior to obtaining the power system measurement;
- obtaining the encrypted power system measurement from the smart contract;
- and
- decrypting the power system measurement using a private key, corresponding to the public key of the receiving device.
A method, comprising:
- obtaining, via a sending device, a power system measurement of a power system during operation;
- encrypting, at the sending device, the power system measurement with a public key of a designated receiving device;
- inserting, via the sending device, the encrypted power system measurement onto a smart contract;
- sending, via the sending device, the smart contract to a pre-defined address of the designated receiving device built into the smart contract during commissioning, prior to obtaining the power system measurement, to cause the power system measurement to be inserted onto a distributed ledger to prevent mutability of the power system measurement;
- and
- decrypting, via the designated receiving device, the power system measurement in the smart contract using a private key, corresponding to the public key of the designated receiving device.
