A method for sending a message, a method and device for verifying a message, and a communication system

Abstract

The present application discloses a method for sending information, a method for verifying information, a device, and a communication system, which belong to the field of communication and can be applied to intelligent vehicles (such as V2X connected vehicles) to acquire environmental data outside the vehicle. The method includes: the sending end obtains the target data to be sent, and the target data is the data to be sent after the first piece of data is sent in the current sending cycle; Obtain the node corresponding to the target data from the hash chain, the number of nodes included in the hash chain is equal to the number of data allowed to be sent in the current sending cycle; The node performs a hash operation to obtain a first verification code, and the first verification code is used by the receiving end to verify the target data; the sending end sends a first message, and the first message includes the target data, the target The node corresponding to the data, the first verification code, and the sending sequence number of the target data. The application can improve the efficiency of message transmission.

Description

technical field [0001] The present application relates to the field of communication, and in particular to a method for sending information, a method and device for verifying information, and a communication system. Background technique [0002] With the continuous development of information technology, intelligent devices such as smart phones, smart TVs, smart speakers, and smart refrigerators are constantly pouring into people's lives, and people are increasingly feeling the convenience brought by intelligence. At the same time, more and more people are paying attention to the intelligentization of vehicles, and the study of intelligentization outside the vehicle is inseparable from the acquisition of environmental data outside the vehicle. [0003] For any vehicle, the vehicle can obtain the external environment data shared by other vehicles. When implementing, each vehicle can send the external environment data to the central server after collecting the external environm...

AI Technical Summary

Problems solved by technology

[0005] At present, the sharing of environmental data outside the vehicle relies on the central server. The process of vehicles obtaining data from the central server is affected by the network status, and there is a certain network delay.
