Data transmission method suitable for trusted connection

Abstract

The invention discloses a data transmission method suitable for trusted connection, and relates to the field of information safety and network communication. According to the method, trusted transmission systems with the same structure are arranged on all network nodes, and trusted data transmission among the network nodes can be achieved through a trusted transmission protocol. The trusted transmission system provides trusted function support for the trusted transmission protocol, a plurality of trusted extension items can be additionally set in transmission data of a trusted transmission protocol layer to describe the trusted attribute cognition of different users to the trusted transmission protocol layer, and the users of the nodes can forward the trusted attribute cognition of other users to the transmission data and can add the trusted attribute cognition of the users to the transmission information. Compared with a traditional data transmission protocol, an extensible and splicing trusted information format is adopted, the attributed trusted connection of the different nodes in the network is achieved, and effective support is provided for trusted forwarding, transmitting and complex trust relation processing under a multi-trusted source mode.

Description

technical field [0001] The invention relates to the fields of information security and network communication, and uses the idea of ​​trusted computing to provide a data transmission method capable of realizing trusted interconnection for different network nodes. Background technique [0002] The 21st century is the age of information. The rapid development of the information technology industry has become a major trend of the current era, and an information revolution centered on information technology has been launched on a global scale, leading to the realization of informatization on a global scale. But on the other hand, with the rapid development of information technology, there are more and more issues related to information security, such as common data security, content security, behavior security and equipment security. In order to ensure the security of information, the security mechanism has become a necessary configuration of the information system. [0003] In...
