Operations of a certificate package verification service may include receiving a first certificate package including a first set of one or more digital certificates, and a digital signature associated with the first certificate package; determining, using a public key of an asymmetric key pair associated with a second set of the one or more digital certificates, that the digital signature is generated using a private key of the asymmetric key pair; and in response to determining that the digital signature is generated using the private key, storing the first certificate packet as a trusted certificate packet in a certificate repository.

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.

The invention discloses a rapid lightweight network trust method suitable for highway vehicle-road cooperation, and the method comprises the steps: carrying out the identity authentication of a target intelligent network connection vehicle through a digital certificate-based strong identity authentication technology at an entrance of a highway, and generating a lightweight network trust certificate of the vehicle; pre-transmitting the lightweight network trust certificate to the intelligent roadside equipment on a subsequent path through the intelligent roadside equipment on the entrance side according to the linear closing characteristic of the expressway; and in the vehicle driving process, information interaction with the intelligent roadside equipment on the subsequent path is carried out in sequence, and the intelligent roadside equipment on the subsequent path carries out identity authentication on the target intelligent network connection vehicle by using the pre-obtained lightweight network trust repertoire verification. According to the method, the identity authentication of the vehicle can be quickly completed during high-speed driving of the vehicle, the authentication efficiency is remarkably improved, meanwhile, the occupied authentication computing resources are small, the network load is greatly reduced, the system safety is enhanced, and the system reliability is improved.

The invention provides a second-hand cargo online transaction system and method. The method comprises the following steps: determining a credible evaluation report; binding the credibility evaluation report with the unique identifier of the second-hand commodity, generating a non-tampering digital credibility certificate, and storing the digital credibility certificate and an out-of-chain storage address index in an alliance chain in an associated manner; when a transaction request is received, providing an estimation confidence interval as a transaction reference based on the digital credible voucher, automatically executing fund trusteeship and on-chain material right circulation record registration after a buyer and a seller confirm a reference opinion, and further generating a new transaction circulation node and writing the new transaction circulation node into a life cycle tracing chain; and when a query request of an authorized user is received, retrieving all transaction transfer nodes in the alliance chain, assembling the transaction transfer nodes to obtain life cycle traceability information, and returning the life cycle traceability information to the authorized user. By adopting the scheme of the invention, full-life-cycle tamper-proof traceability from commodity multi-mode intelligent evaluation to credible automatic transaction execution can be realized.

The network node has a reception section that receives a trust evaluation request message from a specific network node in a case where authentication using a user's attribute / eligibility certificate is successful, the trust evaluation request message including a terminal or the user's trust certificate, a control section that performs a trust evaluation process using the trust certificate, and a transmission section that transmits a trust evaluation result to the specific network node.

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.
