Description
Technical field
The present invention relates to a kind of smart card that has embedded OS, relate in particular to a kind of smart cards that many application can be arranged.
Background technology
Smart card is exactly the integrated circuit card that has CPU, and it is a kind ofly to have the integrated circuit (IC) chip of microprocessor and mass storage etc. and be flush-mounted in the card of making on the substrates such as plastics.COS (Chip operatingSystem chip operating system) is the core technology of smart card, it is generally tightly developed round the characteristics of its smart card of serving, its major function is to control smart card with extraneous message exchange, and the storer in the management smart card is also blocking the inner processing of finishing various command.
Domestic COS majority still is in a common watchdog routine level at present, depends on hardware too much, and closely merges with concrete application, can't cut apart; Change chip platform, COS just can not use, and must from the beginning develop, so the cost of development of smart card is higher; COS places the ROM district in addition, in case mask is finished, the card function also just is difficult to be modified and upgrade, and is unfavorable for the increase of new application service.
At the problems referred to above, Java card and Multos technology have been proposed in the world, wherein Java card is the most representative technology.Java language is the general development language of computer realm, by Java language is improved, all be that application of IC cards is simplified and optimized from virtual machine (VM), language definition to kernel, some special-purpose smart card instructions have been increased, the Java technology can be applied on the smart card, now become the general-purpose platform of smart card designs gradually.And can make client and application developers break away from dependence to COS by Java card, and once write out, can move everywhere, thereby reduce cost greatly.Can realize the cross-platform operation of using on the Java card technical know-how, can solve because the compatibility issue that each card vendor COS difference is brought, so, a kind of new high-end product that Java card has become overseas enterprise actively to promote.But Java card also exists some shortcomings: at first, the Java card technology is not very ripe at present, and cross-platform application does not solve fully; In addition, present Java card efficient is not very high, and very high to the chip performance requirement, Application and Development is very big to the resource consumption of smart card.
Summary of the invention
The present invention is directed to the cost of development height that present smart card exists, the deficiency that function can not be expanded, can not change, provide a kind of cost of development low, can expanded function and can change the smart card of chip platform, technical scheme of the present invention is as follows:
A kind of multi-application smart card, comprise intelligent card chip, chip is provided with microprocessor and the storer that has smart card operating system, described smart card operating system structure is divided into three layers, bottom is a hardware abstraction layer, and the middle level is the kernel software layer, and top layer is an application layer, each layer all is relatively independent subsystems, requires to be provided with some function libraries according to systemic-function in each layer;
Hardware abstraction layer (HAL---Hardware Abstract Layer) is provided with the function library in close relations with hardware, comprises I/O handling function storehouse, EEPROM/FLASH handling function storehouse and other hardware operation function library; The kernel software layer is provided with and comprises the general purpose function storehouse, file system functions storehouse, the function library of safe operation function library; Application layer is provided with the multiple utility function storehouse of satisfying the different application standard, realizing concrete application, comprising VIS1.4, and M/CHIP4.0, PBOC2, GSM11.11, GSM11.14, UIM/UTK, USIM, the utility function storehouse of tax-controlling card;
Comprise the function name device of realizing various functions in each function library, the function name device is divided into two parts, the centre is connected by underscore, previous section is the title device of this function library, and aft section is the concrete function device, and it is to be provided with according to the concrete function that this function name device is realized;
Comprise also in the smart card operating system that the call function name realizes the device of funcall.
Functional device comprises in the above-mentioned HAL function library: IO apparatus for initializing, byte dispensing device, byte receiving trap, change Baud device, programming write data set, wipe FLASH page device and the FLASH device etc. of directly programming.
Functional device comprises in the above-mentioned file operation function library: by the device of record search recorded data addresses, by pattern obtain recorded data addresses device, search the DF file device, search the EF file device, make current file pointed MF file device, create file device, read data device, data writing device etc.
Functional device comprises in the above-mentioned safe function storehouse: according to the authority byte be provided with the safe condition register device, judge whether authority satisfies the device of safe condition, search the device of KEY record.
The functional unit of finishing a certain class function among the present invention is concentrated in together, forms a function library, realizes an independence, complete function.When carrying out function renewal or expansion, only the function of function in the function library is improved, the title of function remains unchanged, to guarantee that other functions can normally use the functional unit in this function library, reduce the influence of the variation of a functional unit to greatest extent to other functional unit in different layers, the different function library; When the chip platform of smart card changes, only need to revise the functional unit in the function library directly related of part in the hardware abstraction layer with hardware, as I/O etc., the function library of other layering all need not to make any modification; When needs increase new application, because application layer is in the superiors of hierarchy, relevant with hardware, general function is by the hardware abstraction layer realization, therefore, do not need or only need increase a spot of power function, can on same smart card, finish the exploitation of new application.If smart card has been selected different chips for use, only need to rewrite the code relevant, and other each instruction level does not need to revise with chip hardware, because the independence of each instruction level, and the unitarity of function naming method, can reduce the modification amount to greatest extent.
When a kind of smart card need be applied to a plurality of industry, by appropriate combination to smart card operating system application layer function library, perhaps function library relevant in the application layer is carried out suitable selection, and in not needing to change, the function library of lower floor, make COS satisfy a plurality of industry standards simultaneously, smart card can be realized inter-trade application, when for example using SIM card to carry out the mobile phone mobile payment, relevant financial application function library or function and SIM card function can be carried out suitable optimal combination, under the support of background system, realize the mobile payment function of mobile phone.
Compared with prior art, the invention has the beneficial effects as follows: can according in the existing smart card, the low side chip platform, improve by part COS system in the smart card, reach and support multicore sheet platform, the many application aims of realization smart card, thereby save greatly the construction cycle of chip cost, shortening smart card.
