Abstract: A method includes: a network function service consumer sends a service request message, where the service request message is used to request to obtain a service provided by a network function service provider. The network function service consumer receives a service response message, where the service response message indicates whether the service request message is accepted, and further indicates a result of trustworthiness verification of the network function service consumer. The method helps the network function service provider verify, before providing the network service, an identity of the network function service consumer and determine whether the network function service consumer is trusted, to help improve security of communication between core network elements and improve security of a core network device.

Abstract: This application provides a communication method and apparatus, to implement blockchain-based communication. In the method, a first communication apparatus sends a first message to a second communication apparatus, where the first message is for requesting to set up data consensus protocol DCP initial access, and the first message includes an identifier of the first communication apparatus and a blockchain identifier. The first communication apparatus receives a second message from the second communication apparatus, where the second message indicates a consensus mode set for blockchain communication. The first communication apparatus sends a third message to the second communication apparatus, where the third message indicates first consensus mode information in the consensus mode set. The first communication apparatus receives a fourth message from the second communication apparatus, where the fourth message indicates that the DCP initial access succeeds or fails.

Abstract: A trusted attestation method and a communication apparatus are provided. The method includes: A first node obtains information about a first blockchain, and the first node determines attestation information based on the information about the first blockchain. The attestation information is used to remotely attest whether the first node is trusted. The information about the first blockchain may be used as a common random number that is generated by the first blockchain based on a consensus and that can be used by a plurality of nodes. Therefore, the information about the first blockchain may be used as a challenge value for performing security measurement by the plurality of nodes. The attestation information may be verified by any verifier to implement measurement for one time and verification for a plurality of times, so that the first node does not need to establish a separate “challenge-response” procedure with each verifier.

Abstract: Embodiments of the present invention disclose a contract management method, apparatus, and system. The method includes: A communication device sends a registration request to a management network element. The registration request includes service request information, and the service request information indicates a specific service. After receiving the registration request from the communication device, the management network element determines a first smart contract based on the service request information in the registration request. Then, the management network element sends the first smart contract to the communication device. According to embodiments of the present invention, service waiting time of a user may be reduced.

Abstract: A method includes sending first information that includes a private key signature of a first blockchain to another apparatus in response to a consensus of another node in the first blockchain network on the first information being successful. The first blockchain includes an apparatus. The second blockchain includes the another apparatus. The method further includes receiving second information that includes a private key signature of the second blockchain network. The second information corresponds to the first information. The method further includes recording the second information on the first blockchain in response to verification on the private key signature of the second blockchain network being successful.

Abstract: This application relates to a communication method and apparatus. A first node sends a first message. The first message includes at least one of request information and information about a first transaction, the request information is used to request to modify a second transaction, the first transaction is a modified second transaction, and the second transaction is stored in a first blockchain. The first blockchain includes N blocks, an ith block in the first blockchain includes a first field and a second field, and the second field is used to store a second preset value or a second hash value of a previous block whose block height is the same as a block height of the ith block. Editability of the block is implemented by using the first hash value, to implement editability of the blockchain.

Abstract: 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 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.
