Detailed Description
In order to make those skilled in the art better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a schematic flowchart illustrating a method for downloading an application to a smart card according to an embodiment of the present invention, where as shown in fig. 1, the method includes the following steps:
step S101: the smart device receives a trigger signal that generates a download application.
In practice, the smart device may provide a selection interface of the application programs available for downloading to the user through the display of the smart device, and the user may perform a selection action on the selection interface, such as clicking, double clicking, swiping, and the like to select the corresponding application program. After the user selects the application program to be downloaded, the user may perform an action for triggering the download, for example, clicking a button such as "download" to complete the above-mentioned triggering action.
In practice, the smart device may be a smartphone, a tablet computer, a Personal Digital Assistant (PDA), or the like.
Step S102: the intelligent device sends request information for acquiring key information of the intelligent card to an On Board Unit (OBU) by means of a communication link between the intelligent device and the OBU.
The OBU is commonly a vehicle-mounted unit of the ETC system, which is installed on a vehicle, and into which a smart card of the ETC system, which is often an ETC system joint credit card issued by a banking institution, is inserted in practice. In the embodiment of the invention, the smart card supports the writing of the application program data, and the writing of the application program data can be completed by the OBU.
In order to verify the identity of the smart card during the downloading of the application, the smart card may be assigned a unique key at the time of issuance.
The present OBU may already support bluetooth communication, for which reason the communication link between the smart device and the OBU may be established based on a bluetooth communication protocol. Of course, those skilled in the art will appreciate that the communication link between the smart device and the OBU may also be established based on other types of peer-to-peer communication protocols, such as WIFI direct, infrared communication, and the like.
Step S103: the OBU sends request information for acquiring the key information of the intelligent card to the intelligent card by means of contact connection with the intelligent card.
The OBU can be provided with a slot, a contact of a reader-writer is arranged in the slot, and when the intelligent card is inserted into the slot of the OBU, the contact of the intelligent card is contacted with the contact of the reader-writer in the slot, so that contact type connection between the intelligent card and the OBU is established.
Step S104: and the smart card reads the key information of the smart card from the local memory according to the received request information and sends the key information to the OBU.
Since the key information of the smart card belongs to sensitive information, the smart card can store the key information in a secure area in the local memory for this purpose, in case any program can read the information at will.
Step S105: and the OBU sends the received key information to the intelligent equipment.
The OBU may send the key information to the smart device via a bluetooth communication protocol, or may send the key information to the smart device via other types of point-to-point communication protocols.
Step S106: the smart device sends a request for downloading the application program to a TSM (Trusted Service Manager) platform, where the request for downloading the application program includes the received key information and the identifier of the application program to be downloaded in step S101.
Step S107: and the TSM platform verifies the identity of the smart card according to the key information in the request for downloading the application program, and determines a corresponding application service provider according to the identifier of the downloaded application program.
In the invention, the smart card can be distributed with a unique key information for identifying the identity of the smart card when being issued, and the key information is registered in the TSM platform at the same time. After receiving the request for downloading the application program, the TSM platform firstly verifies the identity of the smart card, and only the smart card with legal identity has the right to request for downloading the application program.
Step S108: and after verifying that the identity of the smart card is legal, the TSM platform sends the request for downloading the application program to a determined application service provider.
In this example, there are multiple application server providers, labeled application service provider a, application service provider B, … …, respectively. It is not assumed here that the TSM platform determines that the application service provider corresponding to the downloaded application is the application service provider B in step S107, and for this purpose, the TSM platform sends the request for downloading the application to the application service provider B.
Step S109: and the application service provider receiving the request for downloading the application program determines the application program to be downloaded according to the identification of the application program in the request for downloading the application program, and returns the data of the determined application program to the TSM platform.
Step S110: and the TSM platform returns the obtained data of the application program to the intelligent device.
In the embodiment of the invention, the TSM platform and the application service provider jointly form an application program providing platform.
Step S111: and the intelligent device returns the obtained data of the application program to the OBU.
Step S112: the OBU downloads the obtained data of the application program to the smart card through a contact connection.
Step S113: the smart card loads the data of the downloaded application.
In this embodiment, the Data of the Application program sent by the Application service provider to the TSM platform may be completed in the form of an APDU (Application Protocol Data Unit) instruction, the Data of the Application program sent by the TSM platform to the smart device may be completed in the form of an APDU instruction, the Data of the Application program sent by the smart device to the OBU may be completed in the form of an APDU instruction, and the Data of the Application program sent by the OBU to the smart card may be completed in the form of an APDU instruction.
The embodiment of the invention re-develops and utilizes the existing OBU, and the existing OBU can only execute the load operation on the smart card inserted into the OBU at most. In addition, when the problem of downloading applications to the smart card is solved, people usually think that a direct communication connection, such as a bluetooth connection, is established between the smart device and the smart card, but a bluetooth module and other devices with high power consumption and high cost need to be added to the smart card, so that the cost for replacement, configuration and use of a user is increased. Therefore, the scheme of the embodiment of the invention overcomes the usual thinking in the prior art, finishes downloading the application program of the intelligent card by the OBU with single function originally, does not need to carry out essential transformation on the intelligent card, and avoids the increase of the cost of the intelligent card.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate a dedicated integrated circuit chip 2. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Language Description Language), traffic, pl (core unified Programming Language), HDCal, JHDL (Java Hardware Description Language), langue, Lola, HDL, laspam, hardbyscript Description Language (vhr Description Language), and the like, which are currently used by Hardware compiler-software (Hardware Description Language-software). It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory.
Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions.
For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functionality of the units may be implemented in one or more software and/or hardware when implementing the present application.
From the above description of the embodiments, it is clear to those skilled in the art that the present application can be implemented by software plus necessary general hardware platform. With this understanding in mind, the present solution, or portions thereof that contribute to the prior art, may be embodied in the form of a software product, which in a typical configuration includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory. The computer software product may include instructions for causing a computing device (which may be a personal computer, a server, or a network device, etc.) to perform the methods described in the various embodiments or portions of embodiments of the present application. The computer software product may be stored in a memory, which may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium. Computer-readable media, including both non-transitory and non-transitory, removable and non-removable media, may implement information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape magnetic disk storage or other magnetic storage devices, or any other non-transmission medium that can be used to store information that can be accessed by a computing device. As defined herein, computer readable media does not include transitory computer readable media (transient media), such as modulated data signals and carrier waves.
The embodiments in the present specification are described in a progressive manner, and the same and similar parts among the embodiments are referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the system embodiment, since it is substantially similar to the method embodiment, the description is simple, and for the relevant points, reference may be made to the partial description of the method embodiment.
The application is operational with numerous general purpose or special purpose computing system environments or configurations. For example: personal computers, server computers, hand-held or portable devices, tablet-type devices, multiprocessor systems, microprocessor-based systems, set top boxes, programmable consumer electronics, network PCs, minicomputers, mainframe computers, distributed computing environments that include any of the above systems or devices, and the like.
The application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
While the present application has been described with examples, those of ordinary skill in the art will appreciate that there are numerous variations and permutations of the present application without departing from the spirit of the application, and it is intended that the appended claims encompass such variations and permutations without departing from the spirit of the application.
