DEVICE FOR SUPPORTING COMMUNICATION BETWEEN MULTIPLE TYPES OF SAFETY CARRIERS AND COMMUNICATION METHOD THEREFOR

摘要

The invention provides a device and method for supporting communication between various types of secure elements, and pertains to the technical filed of secure information interaction. The device comprises a protocol converter, and the protocol converter comprises: a plurality of communication interfaces for correspondingly coupling with each type of secure element; and a management module coupled with each communication interface; wherein different types of secure elements follow different bottom level communication protocols, each communication interface is configured to follow the same bottom level communication protocol as the secure element it correspondingly couples with; the management module is configured to follow the same upper level communication protocol so as to realize a protocol conversion between any bottom level communication protocol and the upper level communication protocol, and the management module is used for dynamically establishing a connection channel for any two of the communication interfaces, thus realizing a corresponding communication between the secure elements of any two different types. The flexibility, expandability and diversity of the application programs of the secure element are greatly improved.
