In finance, a trust certificate is a corporate bond backed by other securities, usually a parent corporation borrowing against securities of its subsidiaries.
Network node, terminal, and communication method
A network node includes a reception unit that receives a trust evaluation request message including a trust certificate of a terminal or a user from a specific network node that has received a message including the trust certificate from the terminal, a control unit that performs a trust evaluation process using the trust certificate, and a transmission unit that transmits a trust evaluation result to the specific network node.

Securing communication between a PMU and a PDC
ActiveUS12640938B1Key distribution for secure communicationPublic key for secure communicationCommunications securityTimestamp
A method and system for securing communication between a Phasor Measurement Unit (PMU) and a Phasor Data Concentrator (PDC) in accordance with IEEE C37.118.2-2024. The method includes receiving, at the PMU, a command frame requesting an authentication certificate, receiving a configuration frame comprising an X.509 certificate of the PDC, generating a public-private key pair, and transmitting a configuration frame comprising an X.509 certificate of the PMU. Mutual authentication is performed by verifying received certificates using a trusted Certificate Authority. Upon successful authentication, the PMU transmits synchrophasor data messages formatted per IEEE C37.118.2-2024, each appended with a security algorithm field and a FALCON-512 digital signature generated over defined message fields. The PDC verifies signatures using the PMU's public key and authenticates messages only upon successful verification. Replay protection is achieved through SOC timestamp comparison, rendering quantum-resistant, authenticated, and integrity-protected synchrophasor communication without altering the original IEEE C37.118.2 frame structure.
