Problems solved by technology
If the redevelopment of the smart card platform is completed by two parties, one party provides the smart card hardware and embedded operating system, and the other party develops the application code for the application function. Confidentiality, at this time, the disclosure of the embedded operating system and application code will affect the security of both partners
Especially for external cooperation projects, the codes provided by both partners must be guaranteed not to be disclosed to each other in many cases. Obviously, the re-development method of the existing smart card platform cannot meet the requirements

The invention discloses a redeveloping method of smart card flatform, which is characterized by the following: translating and editing executive system code; connecting; generating binary mode file; loading down to smart card; and providing down load order and down load position information of the application code; translating and editing the application code; connecting and generating the binary mode file; basing the down load order; loading down to the down load position of the smart card; registering the entry address information of the application code in the operating system. This invention also discloses a redeveloping system of the smart card flatform. This invention meets the needs of mutually non-public the code of the developing two parts.
Description
technical field [0001] The invention relates to the field of smart cards, in particular to a redevelopment method and system for a smart card platform. Background technique [0002] The popularization and application of smart cards has brought many conveniences to people's daily life. For example, when people take public transportation, they only need to swipe their bus card on the card reader, saving the inconvenience of preparing change in advance; when purchasing expensive items, they only need to swipe their bank card on the POS machine of the merchant to avoid carrying large amounts of money The inconvenience of payment; when entering a place that requires identity verification, you only need to swipe the identity card on the card reader, saving the trouble of identity verification. But often a smart card only has a certain function, which requires the user to carry multiple identity cards with him to deal with different applications. [0003] In order to further faci...
