    摘要： A laser-scanning method may include obtaining scan data captured by a laser scanner in which the laser scanner includes a first private key that uniquely corresponds to the laser scanner. The laser-scanning method may include obtaining a first digital signature corresponding to the obtained scan data that is generated based on the scan data and the first private key. The laser-scanning method may include validating the first digital signature using a first public key that corresponds to the first private key and generating a report that summarizes results of the validating. The laser-scanning method may include transforming and aggregating, by a scan data aggregator, the scan data as aggregated scan data and generating a second digital signature corresponding to the aggregated scan data. The second digital signature may be generated by signing hashes corresponding to the aggregated scan data using a second private key corresponding to the scan data aggregator.

    摘要： Embodiments of the present disclosure relate to network function validation. the first network device receives, from a second network device, a request including profile information of the second network device to be validated, obtain registered profile information of the second network device from a third network device maintaining a blockchain ledger storing the registered profile information, and validate the profile information of the second network device based on the registered profile information. The validation can be implemented via blockchain, and OAuth is not need, and for pure consumer can be authorized, in addition, information for validation is sufficient.

    摘要： Regarding an information intermediary system, in which a providing-side terminal device, an intermediary device, and a receiving-side terminal device are assigned with first to third public keys and first to third secret keys, the providing-side terminal device generates first encrypted data by encrypting provided data with the third public key, and also generates a first electronic signature using the first secret key, and transmits the first encrypted data and the first electronic signature to the intermediary device; the intermediary device generates a second electronic signature using the second secret key, and transmits the first encrypted data, the first electronic signature, and the second electronic signature to the receiving-side terminal device; and the receiving-side terminal device decrypts the first encrypted data with the third secret key to obtain the provided data, and also verifies the first electronic signature with the first public key and verifies the second electronic signature with the second public key.

    摘要： This application provides a method and an apparatus for editing a block chain. The method for editing a block chain includes: A first node receives a request message used to request to edit data, and performs endorsement on the request message to generate an endorsement result. Further, the first node sends the endorsement result to each of at least one second node, where the at least one second node belongs to a second node set. The first node is any one of a plurality of nodes with an endorsement function in the block chain, each of the at least one second node knows a private key slice corresponding to the second node and a public key corresponding to the second node set, and the public key is determined based on at least one public key slice respectively corresponding to the at least one second node. The node with the endorsement function in the block chain performs endorsement on an editing request, and sends an endorsement result to a node with an editing function, to implement block chain editing while improving security assurance.
