Method and device for implementing multiple operation software intelligent card chip

Abstract

The invention relates to a method and apparatus for implementing a multi-business software smart card chip. The method comprises that: a novel memory, for implementing the operation of stored independently of each other between a plurality of business software codes through a core operating system and separated on the hardware using business software system, can implement the safe protection and coexistence between different source business software, the valid check and the treatment for illegal operation of the core operating system and the business software code are implemented by the hardware circuit. The apparatus includes: a business software module independent memory and hardware separating area for implementing the operation for stored independently of each other by the core operating system and each business software module code and separated on the hardware; a valid operation check module for judging the range of present operating application software business functional module, and transmitting the illegal operation indicating signal beyond the range to the illegal operation treating module; an illegal operation treating module for treating the illegal operation indicating signal transmitted by the valid operation check module, and carrying out the optimization process for the part control signal of the smart card chip.

Description

technical field [0001] The invention relates to a method and a device for realizing a multi-service software smart card chip, in particular to a method and a device for a highly compatible smart card chip capable of supporting service software modules from different designers. Background technique [0002] A smart chip card is a card based on an integrated circuit chip. It is currently widely used in personal identification, financial user information identification, mobile phone user identification, IC phone card, and radio and television information authorization reception. It is also often referred to as a smart card. , or called an integrated circuit card (IC card). [0003] Generally, user identification cards can record user information by means of barcode, photoelectricity, magnetic stripe and smart chip. Smart chip card is a solution with the highest storage capacity and security, because the chip has a larger storage capacity and more Strong information processing ...

Problems solved by technology

At present, these integrated business software modules are usually provided by the same card issuer or institution. As mentioned above, the isolation and security protection of the application business software modules on the card are not perfect enough. At present, it is still necessary to rely on The core operating system software or underlying application management software on the card is implemented, which makes the security of the card closely related to the reliability of the software. It is difficult for the application business software modules from different card issuers to be trusted to work together.
