Abstract
The present invention discloses a method for configuring a smart card. By modifying configuration control logic, a user can select for the smart card one or more enciphering IP core which can realize a required enciphering function, a communication IP core which can realize a required communication interface function and a memory capacity which is in accordance with the application requirement. After the configuration is completed, IP cores of various functions, memory capacities and configuration control logic which are not selected are invisible to an application. A smart card which is in accordance with specific application requirements can be configured simply and rapidly by using the present invention, the development cost, time and risk of a product are effectively reduced, and the final used is not influenced. The present invention can be used widely in smart card businesses which have different requirements.
Description
Technical field
The present invention relates to the digital information applications technology, relate in particular to a kind of collocation method of smart card.
Background technology
In recent years, all kinds of smart cards rise rapidly, and have obtained widespread use in various fields, and in order to satisfy various concrete application demand, configuration, the kind of smart card increase day by day.Especially after entering 21 century, along with the continuous refinement of application, smart card relevant interface technology, memory technology, and the develop rapidly of encryption technology etc., the application of various various objectives is according to the difference that oneself stresses face, and the configuration requirement of smart card is more become clear and definite and concrete.In order to accomplish " the most suitable " oneself application requirements, system integrator often requires the concrete application customized a configuration the most satisfactory smart card product of smart card production firm for oneself.
But problem has also occurred thereupon.Since various application stress the face difference, the application that has may stress high security, just the encryption section of smart card more is concerned about; The application that has may stress use more, and just the memory span to smart card has certain requirement; The application that has is fairly simple, but requires more special communication interface.So just caused smart card manufacturer in order to satisfy multiple application requirements on the market, very strong very many different cultivars, the smart card product of configuration developed targetedly must have been arranged.Sometimes in order to satisfy a concrete requirement of using, have to drop into again the product that human and material resources are developed a brand-new configuration, and may only there be very little difference in it with existing matured product in configuration.
In this process, be responsible for user oriented and realize that the final system integrator that uses in order to take optimal product, may need to wait the last a very long time, smart card manufacturer then needs to drop into very big cost of development and production, testing cost.Yet, wait as long for the delay that causes the corresponding software exploitation, finally causing losing of market is that system integrator is unwilling to see; The input of the significant cost that repeats, and to bear the unnecessary risk of bringing thus also be that smart card manufacturer is undesirable, but do not meet the product of concrete application requirements in the existing procucts again really.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of collocation method of smart card, and it can configure the smart card that meets concrete application requirements simply, efficiently, effectively reduces Products Development cost, time and risk, and does not influence final use.
For solving the problems of the technologies described above, the collocation method of smart card of the present invention is, its inside has been reserved several encryption IP kernels of realizing encryption function and has been realized the IP kernel of communicating by letter of communication interface with several, and configurable memory space, also has configuration steering logic and interface, for making the smart card configuration feature meet application requirements, by revising the configuration steering logic, select to realize one or several encryption IP kernel of desired encryption function for smart card, selection can realize the communication IP kernel of desired communication interface function, and selection can meet the memory span of application requirements.
Owing to all be that it also is reliable and stable reconfiguring the smart card of finishing through practical proof, mature and reliable on each function IP kernel and the interfacing thereof, only needing just can delivery system developer use through test again, and meets concrete application requirements.
The process that this reconfigures does not involve redesign, flow, only need be configured, and can reduce time of product development and expense, avoids designing, the risk in the flow process, and product can be come into the market faster, seizes commercial opportunity.
Description of drawings
Below in conjunction with drawings and Examples the present invention is described in further detail:
Fig. 1 is a smart card architecture block diagram of using method configuration of the present invention;
Fig. 2 is example block diagram of smart card visible structure after application method configuration of the present invention is finished.
Embodiment
As shown in Figure 1, in the collocation method of smart card of the present invention, comprise the IP kernel of processor cores, several realization encryption functions, the IP kernel of several realization communication interfaces, the storage space of configurable capacity, and configuration steering logic and interface thereof.
After using the configuration of method realization smart card of the present invention, by the interface of configuration steering logic, it all is visible that inner each encrypted IP kernel, communication IP kernel and whole storage space.By interface the configuration steering logic is operated, control it and select one or several to encrypt IP kernel, and shield other unwanted encryption IP kernels; Select the communication IP kernel of requirement, and shield other unwanted communication IP kernels; Select the memory span of requirement; Close configuration steering logic and interface thereof at last.
As shown in Figure 2, after aforesaid operations was finished, for application, it was visible only selectively encrypting IP kernel, the communication IP kernel of selection and the memory span of requirement.
By the interface of configuration steering logic, it all is visible that all of smartcard internal are encrypted IP kernel, communication IP kernel and whole storage space.
Configuration steering logic and interface can be closed after using as requested.After closing, non-selected encryption IP kernel, communication IP kernel, storage space all are sightless to using, and do not influence the user and finally use.The final smart card product of using of user is consistent with the smart card that redesign, flow are come out.
In sum, the collocation method of smart card of the present invention, its configuration is simple, quick, meets the requirement of concrete application, has reduced Products Development cost, time and risk simultaneously, and has not influenced final use.
