Description

Technical Field

[0001] The present invention relates to the field of communication technology, and in particular to a communication method for standardizing a communication machine interface. Background Art

[0002] Communication machine interface standardization is to develop a set of unified specifications and standards in the field of communication to provide effective communication and exchange between different devices, systems or platforms. These standards define the format, protocol, interface, electrical characteristics and other related parameters of data transmission, so that devices produced by different manufacturers can be compatible with each other and exchange data smoothly.

[0003] The importance of communication machine interface standardization lies in that it promotes cooperation between different manufacturers, reduces barriers to interoperability between devices, and improves the reliability and stability of the entire communication system. In this way, users can choose products from different manufacturers more flexibly without worrying about communication problems caused by incompatibility. In the field of communications, there are many different standardization organizations and institutions responsible for formulating various communication protocols and interface standards, such as the International Telecommunication Union (ITU), the International Organization for Standardization (ISO), the Institute of Electronic Engineers (IEEE), etc. These organizations will consider technological development, market demand and industry trends, formulate communication standards, and thus promote the development and application of communication technology. Communication machine interface standardization is the basis for providing seamless communication between different devices and systems. It plays a key role in promoting technological development and promoting industrial progress.

[0004] However, in traditional communication methods, since data is stored in a central server, there is a risk of tampering or unauthorized access. At the same time, the device's identity authentication and permission management mechanisms may not be sound enough, which can easily lead to illegal access and tampering of data. This may lead to wrong decisions in the system, misleading information dissemination, and even serious impact on business processes and decisions. If the data in a communication method with security protection is not properly encrypted, it will still not be able to effectively protect against data leakage. Unauthorized visitors may obtain sensitive information involving user privacy, business secrets, etc., which may cause privacy leakage problems, resulting in infringement of user privacy and damage to corporate reputation. Therefore, there is an urgent need for a highly secure, decentralized communication method with standardized communication machine interfaces. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies of the prior art, the present invention provides a communication method for standardizing the communication machine interface, which solves the problem in the prior art that the data set stored in the central server is prone to illegal access and tampering of the data, and cannot be effectively protected against data leakage.
