Abstract: Embodiments of this application provide a packet transmission method and apparatus, and relate to the field of communication technologies. When the packet transmission method is applied, a first packet may be determined by using a first device, where packet fields of the first packet include an authentication identifier field, an authentication code field, and at least one candidate authentication field, and the authentication identifier field indicates a field that is in the at least one candidate authentication field and that corresponds to the authentication code field; and then the first packet is sent.

Abstract: Embodiments of this application disclose an identity authentication system, method, apparatus, and device, and a computer-readable storage medium, and belong to the field of security technologies. In an embodiment of this application, a symmetric key based identity verification method is implemented by sharing the first symmetric key between the terminal device and the authorization device. In this way, when confidentiality of the symmetric key is ensured, authentication code generated based on the symmetric key in an entire identity authentication process is not easily forged, so that security and reliability of identity authentication can be ensured.

Abstract: This application provides a packet processing method and apparatus, to avoid chain impact of an abnormal packet caused by an abnormal underlying latency on an uncertain target flow. The method includes: receiving, by a first device, a first packet sent by a second device, where the first packet carries a first label, and the first label is determined based on a cycle in which the second device sends the first packet; determining, by the first device based on the first label, whether the first packet is a normal packet; if determining that the first packet is a normal packet, determining, by the first device, a second packet based on the first packet, where the second packet carries a second label; and sending, by the first device, the second packet to a third device in a first cycle, where the second label is determined based on the first cycle.

Abstract: Embodiments of this application provide a method and an apparatus for establishing a blockchain node connection, and a device. The method is applied to a blockchain system, and includes: A first node obtains address information of a second node from a first router. The first router and the first node are located in a first autonomous system. The second node is located in a second autonomous system. The first autonomous system and the second autonomous system are neighboring autonomous systems. The first node establishes a connection to the second node based on the address information of the second node. This improves blockchain communication security.
