Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims. The embodiments in the present application may be implemented individually or in combination without conflict.
Fig. 1A is a schematic flow chart of a data acquisition method according to an embodiment of the present application, and referring to fig. 1A, the embodiment provides a data acquisition method for implementing data acquisition on different types of smart cards and improving the generalization of a data acquisition scheme, and specifically, the embodiment exemplifies that the data acquisition method is applied to a data acquisition device, and the method includes:
101. acquiring information of a smart card to be tested;
102. determining a data acquisition protocol corresponding to the smart card to be tested according to the information of the smart card to be tested;
103. and acquiring data of transmission data between the intelligent card to be detected and the terminal by adopting the data acquisition protocol.
In practical applications, the execution subject of this embodiment may be a data acquisition device, and the data acquisition device may be a driver, program code software, or a medium storing related execution codes, such as a usb disk, a non-volatile memory (EEPROM, flash), or the like; alternatively, the data acquisition device may also be an entity device integrated or installed with a relevant execution code, for example, a chip, a micro controller Unit (MCU for short), a computer, and the like.
Combining the actual scene for example: the data acquisition device in this application supports multiple data acquisition protocol, and is specific, can install multiple data acquisition protocol in data acquisition device in advance, realizes the support to multiple data acquisition protocol. Subsequently, when the smart card needs to be tested, the data acquisition device selects a corresponding data acquisition protocol according to the currently connected smart card to be tested to acquire data. The information of the smart card to be tested is used to query a data acquisition protocol applicable to the smart card to be tested, and the content of the information may include, but is not limited to, the type and/or the identifier of the smart card to be tested. Correspondingly, 101 may specifically include: and acquiring the type of the smart card to be tested and/or the identification of the smart card to be tested.
In practical applications, the types of smart cards have diversified characteristics. For example, when the smart card performs data interaction with the outside, the data stream can be input and output in a data bit mode; the input and the output can be carried out according to a byte mode; the input and output can also be carried out in a data packet mode. Data transmission may employ different communication rates through negotiation. Because the data transmission protocols adopted by different intelligent cards are different, the data acquisition protocols supported by different intelligent cards are correspondingly different. According to the data acquisition scheme, multiple data acquisition protocols are configured in advance, when data acquisition is needed, the data acquisition protocols which correspondingly support the types of the smart cards are selected for data acquisition according to the smart cards needing data acquisition at present, and data acquisition of the smart cards of different types is achieved, so that the universalization of data acquisition is improved.
The terminal is used for interacting with the smart card to be tested and sending an execution command to be tested to the smart card to be tested. In practical applications, the terminal may include, but is not limited to, an electronic device capable of interacting with a smart card, such as a computer, a PAD, and a smart phone. In one embodiment, the test communication between the smart card and the terminal may be implemented by command-response pairs.
Correspondingly, as shown in fig. 1B, as an implementation manner, on the basis of any other implementation manner, 103 may specifically include:
1031. receiving a first execution command sent by a terminal;
1032. sending the first execution command to the smart card to be tested, and receiving first execution response data returned by the smart card to be tested;
1033. and generating corresponding log records aiming at the first execution command and the first execution response data, and sending the first execution response data to the terminal.
Specifically, the terminal sends an execution command to the smart card, for example, the execution command may be in the form of a C-APDU, and after receiving the execution command, the smart card executes corresponding processing and then returns execution response data (e.g., a processing result) to the terminal. Optionally, the smart card may package the execution response data into a response message, and return the response message to the terminal in the form of an R-APDU. With the adoption of the method and the device, in the process that the smart card performs the data interaction with the terminal through the data acquisition device, the data acquisition device generates and stores the log record about the current execution at the same time or before sending the execution response data returned by the smart card to the terminal. The content of the log record can be set according to the requirement of the smart card test. Alternatively, the log records may include execution command and execution response data.
As a further alternative, in order to save the storage space of the data acquisition device, as shown in fig. 1C, on the basis of the embodiment shown in fig. 1B, the log record may include the command identifier of the first execution command and the first execution response data; correspondingly, after 1031, it may further include:
1034. and determining the command identifier of the first execution command according to the command identifier of each execution command.
Specifically, a unique command identifier may be assigned to each execution command in the field of smart card testing in advance, and the form of the command identifier may be set to a format with small data, for example, a number code 01, 02, or the like, or may be a combination of letters and numbers, for example, a1, b3, or the like, or may be an abbreviation of the execution command, and the like, which is not limited herein. Subsequently, when the log record is generated, the command identification and the execution response data of the execution command can be recorded, and the data of the command identification is usually shorter, so that the data size of the log record and the data acquisition data volume can be effectively reduced, the data acquisition efficiency is improved, and the storage space is saved.
In addition, to facilitate subsequent reading of log records, a time dimension may also be added to each log record. Accordingly, in any embodiment, the log record further includes a log time; as shown in fig. 1D, the method further comprises:
104. and recording the moment of receiving the first execution command to obtain the log time.
Specifically, when the data acquisition device receives an execution command sent by the terminal, the data acquisition device records the time when the execution command is received, and forwards the received execution command to the smart card to be tested, and the smart card to be tested processes the execution command and returns execution response data to the terminal through the data acquisition device. When a certain log record needs to be read from all currently recorded log records subsequently, the log time can be used as an index, and the log record needing to be read can be conveniently and quickly found.
Based on the foregoing embodiment, optionally, the method further includes:
and returning a log record to the terminal according to the reading instruction sent by the terminal.
The terminal of the present embodiment is configured to read data in the data acquisition device by sending a reading instruction, and the terminal may be the same terminal as or different from a terminal used for data acquisition in other embodiments. In practical applications, the terminal of the present embodiment may also include, but is not limited to, an electronic device capable of interacting with a smart card, such as a computer, a PAD, and a smart phone. Specifically, the read data may be used for data unloading, data analysis, test analysis, and the like, and is not limited herein.
The data acquisition method provided by this embodiment is to pre-configure a plurality of data acquisition protocols, when a smart card test is performed, first obtain information of a smart card to be tested, determine a data acquisition protocol suitable for the smart card to be tested according to the information, and acquire interactive data between the smart card to be tested and the outside world by using the determined data acquisition protocol. The integration of different data acquisition protocols is realized to above-mentioned scheme, utilizes same data acquisition device convenient and fast ground to realize the data acquisition to different grade type smart card, effectively improves the commonality of data acquisition scheme to need not the tester and confirm the data acquisition device that needs to use at present, can avoid artifical erroneous judgement to lead to unable data acquisition, convenient to use management.
In practical applications, it may also be related to upgrading functions supported by the data acquisition device based on test requirements, and the software upgrading for the data acquisition device is exemplified below.
In practical application, by performing software upgrading, a good use effect can be achieved, for example, functions of data analysis, data reading and the like can be added, or a more optimized operation interface and the like can be provided, so that a user can use and operate the software conveniently. However, unlike other general software upgrades, in a special application scenario of the smart card, since the smart card generally relates to personal information and privacy of a user, security of the software upgrade needs to be considered while the software upgrade is performed.
To this end, fig. 2 is a schematic flow diagram of a data acquisition method provided in the second embodiment of the present application, and referring to fig. 2, this embodiment provides a data acquisition method for upgrading software on the premise of ensuring data security, and specifically, on the basis of the first embodiment, the data acquisition method further includes:
201. acquiring an upgrading program carrying authority encryption;
202. verifying by using an upgrading secret key corresponding to a pre-distributed unique serial number so as to obtain upgrading authority after successful verification;
203. decrypting the upgrading program by using the decryption secret key corresponding to the serial number to obtain the decrypted upgrading program;
204. and running the decrypted upgrading program according to the obtained upgrading authority so as to finish the firmware upgrading.
Specifically, in this embodiment, a unique serial number is assigned to each data acquisition device in advance, and in practical application, the serial number may be fixed and written in the data acquisition device, and an editing authority is set. Preferably, the serial number may be randomly generated and encrypted to further ensure the security of the software upgrade.
Combining the actual scene for example: in practical application, software upgrading management can be performed through a remote server. Specifically, the upgrade program for performing software upgrade may be issued by the server, and the issuing manner (i.e., the manner in which the data acquisition device acquires the upgrade program) may be multiple, for example, the data acquisition device may access the network to directly download the upgrade program, or the data acquisition device may support data transmission with a storage medium (e.g., a usb disk) to acquire the upgrade program from the storage medium. Preferably, in order to ensure the stability of software upgrade, the data acquisition device may be connected to a terminal (e.g., a personal computer), and a user downloads an upgrade program through the terminal and transmits the upgrade program to the data acquisition device, so that the data acquisition device is controlled by the terminal to execute an upgrade process, thereby finally implementing software upgrade on the data acquisition device.
In practical application, the serial numbers of all the data acquisition devices are stored in the server, when an upgrading program required by software upgrading is provided for a certain data acquisition device, upgrading authority verification is set for the upgrading program according to the serial numbers of the data acquisition devices, the upgrading program is encrypted to obtain an upgrading program with encrypted carrying authority, and the upgrading program with the encrypted carrying authority is subsequently provided for the data acquisition devices. Correspondingly, the legal data acquisition device carries out authority verification according to the upgrading key corresponding to the serial number of the legal data acquisition device, if the verification is successful, the upgrading authority is obtained, after the upgrading authority is obtained, the upgrading program is decrypted according to the decryption key corresponding to the serial number of the legal data acquisition device, the decrypted upgrading program is obtained, and then the software upgrading is realized by operating the upgrading program. Optionally, the upgrade program may be specifically configured to complete software upgrade by replacing a code program for implementing data acquisition in the data acquisition device.
In the data acquisition method provided by this embodiment, the server issues an upgrade program carrying authority encryption according to a unique serial number of the data acquisition device, and after acquiring the upgrade program, the data acquisition device acquires the upgrade authority and decrypts the upgrade program by using an upgrade key and a decryption key corresponding to its own serial number, thereby implementing software upgrade and ensuring security while implementing software upgrade.
In addition, the present solution also relates to the integration and management of data acquisition protocols.

301. receiving a first protocol program, wherein the first protocol program is used for installing a newly-added data acquisition protocol;
302. and operating a first protocol program to install the newly added data acquisition protocol.
Combining the actual scene for example: in practical applications, a new data acquisition protocol may be added to the data acquisition device, for example, if a new type of smart card is available, a data acquisition protocol suitable for the smart card needs to be added, or if a new data acquisition protocol is developed for an existing smart card, the data acquisition protocol configured in the data acquisition device may be expanded. Specifically, the protocol program for installing the new data acquisition protocol may be obtained from the outside. For example, the data acquisition protocol with the new addition sent by the server may be received, or may be acquired from a storage medium, or may be acquired from the terminal. The terminal may be the same terminal as that in the foregoing embodiments or may be different terminals. And after a protocol program for installing the newly added data acquisition protocol is acquired, the newly added data acquisition protocol is installed by operating the protocol program.
Through the embodiment, the data acquisition protocol supported by the data acquisition device can be newly added according to the data acquisition requirement, and the universality and the reliability of data acquisition are further improved.
Fig. 3B is a schematic flow chart of another data collection method provided in the third embodiment of the present application, and referring to fig. 3B, this embodiment provides a data collection method for supporting data collection of a new smart card, specifically, on the basis of any other embodiment, the data collection method further includes:
303. if the data acquisition protocol corresponding to the smart card to be tested does not exist currently, sending the information of the smart card to be tested to a server;
304. receiving a second protocol program returned by the server, wherein the second protocol program is used for installing a data acquisition protocol corresponding to the smart card to be tested;
305. and operating the protocol program to install the data acquisition protocol corresponding to the intelligent card to be tested.
Combining the actual scene for example: and during actual data acquisition, if the current data acquisition protocol library is searched, and a data acquisition protocol suitable for the current intelligent card to be detected is not found, the information of the current intelligent card to be detected is sent to the server, the server searches the data acquisition protocol matched with the intelligent card to be detected from the local protocol library, generates a protocol program for installing the data acquisition protocol, and returns the protocol program to the data acquisition device. The data acquisition device completes the installation of the data acquisition protocol suitable for the current smart card to be tested by operating the protocol program.
Through the embodiment, when the local protocol library of the data acquisition device does not have the data acquisition protocol suitable for the current smart card to be detected, the server is requested to acquire the corresponding data acquisition protocol for installation, so that the universality and the reliability of data acquisition are further improved.

306. if a data acquisition protocol compatible with the terminal does not exist currently, sending information of the intelligent card to be detected and the terminal to a server;
307. receiving a third protocol program returned by the server, wherein the third protocol program is used for upgrading the current data acquisition protocol;
308. and running the third protocol program to upgrade the current data acquisition protocol, wherein the upgraded data acquisition protocol is compatible with the terminal.
Combining the actual scene for example: during data acquisition, interactive data between the intelligent card to be detected and the terminal are acquired, so that a data acquisition protocol in the data acquisition device needs to be configured with a data acquisition protocol suitable for the terminal besides a protocol suitable for the intelligent card. Specifically, if the current data acquisition protocol library is searched, and a data acquisition protocol compatible with the terminal is not found, the information of the current smart card to be tested and the terminal is sent to the server, the server searches for the data acquisition protocol compatible with the terminal from the local protocol library, generates a protocol program for installing the data acquisition protocol, and returns the protocol program to the data acquisition device. The data acquisition device completes the installation of the data acquisition protocol of the compatible terminal by operating the protocol program.
By the embodiment, when the local protocol library of the data acquisition device does not have the data acquisition protocol compatible with the current terminal, the server is requested to acquire the compatible data acquisition protocol for installation, so that the reliability of data acquisition is further improved.
According to the data acquisition method provided by the embodiment, the installation programs of the corresponding data acquisition protocols are acquired and installed aiming at different scenes, so that the universality and the reliability of data acquisition are further improved. The above embodiments may be implemented individually or in combination.

Specifically, a unique command identifier may be assigned to each execution command in the field of smart card testing in advance. When the processing unit generates the log record, the command identification of the execution command and the execution response data can be recorded, the data size of the log record and the data volume of data acquisition can be effectively reduced, the data acquisition efficiency is improved, and the storage space is saved.
In addition, to facilitate subsequent reading of log records, a time dimension may also be added to each log record. Accordingly, in any embodiment, the log record further includes a log time; and the processing unit is also used for recording the moment of receiving the first execution command so as to obtain the log time.
Specifically, when a communication unit of the data acquisition device receives an execution command sent by the terminal, a processing unit records the time when the execution command is received, the communication unit forwards the received execution command to the smart card to be tested, the smart card to be tested processes the execution command according to the execution command, and execution response data is returned to the terminal through the communication unit of the data acquisition device. And the log time can be used as an index subsequently, so that the log record needing to be read can be conveniently and quickly found.
