Abstract

The invention discloses a method and a device for achieving multi-pipe data transmission in an embedded system. The multi-pipe data transmission is achieved by creating a dynamic channel between entities in a host computer network; and a corresponding transmission buffer zone is arranged for each pipe. Thus, the situation the pipes may cross is avoided; a data transmission error between the entities is reduced, and the reliability of data transmission is improved. The dynamic pipe can be dynamically created and deleted, so that long-term occupation of management resources is avoided; and the resources of the host computer are saved. In addition, by adopting the technical scheme provided by the invention, centralized control also can be achieved; a network topology is supported, and the device is simple in facility, convenient to deploy, suitable for various application scenes, strong in error handling capacity and compatible with various hardware platforms, and supports a plurality of data carriers at the bottom layer.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and device for realizing multi-pipeline data transmission in an embedded system. Background technique [0002] In recent years, with the promotion of the application of smart cards in industries such as finance, commerce, and transportation, more and more applications need to be implemented and supported on smart cards. Smart cards not only have data storage functions, but also have functions such as command processing and data security protection. The data and keys inside the card are protected by the built-in smart card operating system, and it is impossible for the outside to directly operate on the data or keys in the card beyond the control of the COS. Smart cards can use contact or non-contact interfaces to communicate with external systems, and are widely used in fields with high security requirements such as finance, telecommunications, transportation, an...
