Embodiment Construction

[0037] In order to make the object, technical solution, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0038] The main idea of ​​the present invention is: after checking the security mechanism of the received command header, judge the service type, if the command header indicates that the service type is ordinary data service, then perform ordinary data service processing; if the command header indicates that the service type is high-speed For data services, perform high-speed data service processing.

[0039] According to the ISO7816 protocol, the smart card interface parsing command is carried out by judging the five command bytes, that is, the first five bytes received are used as the command header, indicating what operation the command is to complete; the subsequent bytes are information words section, indicating the information carried by the comm...

Abstract

The invention discloses an on-chip operating system of a dual-interface smart card and a realization method thereof, the system comprises: a smart card interface transmission management module, a high speed interface transmission management module, a security management module, an application management module, a file management module and a high speed data co-processing module; the inventive method judges type of services via performing a security mechanism checkup for a received order head, if the order head represents the type of services is general data service, a general data service processing is carried out; if the order head represents the type of services is high speed data service, a high speed data service processing is carried out. The inventive on-chip operating system and the realization method thereof can be applied to the dual-interface smart card having a high speed data interface, which shakes off limit of conditions in conventional smart card interface such that transmission for high speed data is possible.

Description

technical field [0001] The invention relates to the field of smart cards, in particular to an on-chip operating system (COS, chip operating system) of a dual-interface smart card and an implementation method thereof. Background technique [0002] At present, with the continuous advancement of technology, smart card applications have gradually become an indispensable part of people's lives, and are mainly used in industries with high security requirements. From building access control to mobile phones, from bus cards to campus cards, from bank cards to conditional access (CA, conditional access) cards in digital TVs, many applications are closely related to smart cards. With the continuous promotion and popularization of smart card applications, people's functional requirements for smart cards are becoming more and more diverse. The rich and colorful application requirements make the hardware technology level of smart cards change with each passing day. [0003] The rapid de...
