Problems solved by technology

[0002] At present, access between data stored in the same data card cannot be controlled by authority. For example, a SIM card that can be used for mobile payment based on the CIOS (Card IO Management System) / COS (Chip Operating System) architecture, its Software Structure Diagram Reference figure 1 , figure 1 It is a schematic diagram of CIOS / COS architecture in the prior art, including CIOS layer, COS layer and application layer. CIOS layer includes CIOS interface management, 7816 master / slave module, radio frequency, security module, etc.; COS layer includes application API, SIM, business support COS , COS interface management, etc.; the application layer includes various applications, such as application APP1, application APP2, application APP3, etc., such as mobile wallet, mobile ticket, enterprise card and other applications
The existing FLASH space of the SIM card that can be used for mobile payment based on the CIOS / COS architecture only divides the data area and the code area. The same data area stores COS data, CIOS data, application data and algorithm library data, etc., and the same code area Store COS codes, CIOS codes, application codes, and algorithm library codes, etc. Therefore, data access and code access between COS, CIOS, and application layers are controlled by authority, which is not conducive to joint development by multiple parties
