The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.
The embodiment of the application provides a read-write method of an NFC card, which is applied to a mobile terminal, wherein the NFC card is a card recorded by the mobile terminal through NFC, and FIG. 1 is a schematic flow chart of an alternative read-write method of the NFC card, as shown in FIG. 1, the read-write method of the NFC card can comprise the following steps:
s101, when a read-write signal of card information aiming at an NFC card is received, acquiring configuration information of the NFC card;
At present, when the mobile terminal utilizes NFC to realize a card simulation function, card information of the NFC card is usually stored in an eSE and a main memory, however, when the NFC card is stored by using a memory other than the eSE in the mobile terminal, the security of the NFC card is threatened, so that the security problem of the NFC card exists.
In order to improve the security of the NFC card, when the configuration information of the NFC card is configured, the security index of the storage location of the card information of the NFC card in the configuration information of the NFC card is positively correlated with the security index of the NFC card, that is, the storage location of the card information of the NFC card is determined according to the security index of the NFC card, for example, the storage location of the card information of the NFC card with a high security index is determined as the storage location with a high security index, such as eSE, the storage location of the card information of the NFC card with a low security index is determined as the storage location with a low security index, such as a memory other than eSE, the routing information of the card information of the NFC card is the routing information corresponding to the storage location, such as eSE, and the routing information corresponding to the memory is Host-based card simulation (Host-based Card Emulation, HCE), that is, the card information of the NFC card is stored to the storage location corresponding to the security index positively correlated with the security index of the card information.
It should be noted that, the configuration information of the NFC card may include a storage location of card information of the NFC card, routing information of card information of the NFC card, a storage location of card data of the NFC card and routing information of card data of the NFC card, where, because each storage location corresponds to the routing information, the storage location of card information of the NFC card corresponds to the routing information of card information of the NFC card, and the storage location of card data of the NFC card corresponds to the routing information of card data of the NFC card.
The memory other than the eSE may be an internal memory of the mobile terminal or an external memory of the mobile terminal, which is not particularly limited in the embodiment of the present application.
In an alternative embodiment, the memory of the mobile terminal includes one or more of the following:
main memory, subscriber identity Module (Subscriber Identity Module, SIM) card, SD Secure digital card (Secure DIGITAL CARD, SD) card.
It can be understood that when the memory is the main memory of the mobile terminal, the routing information corresponding to the memory is HCE, when the memory is the SIM card inserted into the mobile terminal, the routing information corresponding to the memory is SIM, and when the memory is the SD card of the mobile terminal, the routing information corresponding to the memory is SD.
The memory may be one or more of a main memory, a SIM card and an SD card, which is not particularly limited in this embodiment of the present application.
In addition, since the mobile terminal has the routing information corresponding to each storage location, when the card information of the NFC card is stored in the eSE or a memory other than the eSE, the routing information corresponding to the eSE or the memory is determined as the routing information of the card information of the NFC card.
S102, responding to read-write signals of card information of the NFC card based on configuration information of the NFC card.
That is, after the storage location of the card information of the NFC card and the routing information of the card information of the NFC card are acquired, the read/write signal of the card information of the NFC card may be responded based on the storage location of the card information of the NFC card and the routing information of the card information of the NFC card.
When the mobile terminal receives the read-write signal of the card information of the access card, the memory of the card information of the access card is obtained from the configuration information of the NFC card, wherein the memory is a memory except for the main eSE, the route information of the card information of the access card is HCE, and the read-write signal of the card information of the access card is responded based on the main memory and the HCE, so that the card simulation of the access card is realized.
In this way, the card information of the NFC card is stored to the storage position corresponding to the security index positively correlated to the security index of the card information by utilizing the preset configuration information of the NFC card, so that the NFC card with higher security index can store the card information to the storage position with higher security index, and the security of the NFC card is improved.
In order to obtain the configuration information of the NFC card, the developer may be configured according to positive correlation between the security index of the NFC card and the security index of the storage location of the card information of the NFC card, or may be configured according to positive correlation between the security index of the NFC card of the mobile terminal and the security index of the storage location of the card information of the NFC card, where the embodiment of the present application is not limited specifically.
Further, in order to improve the security of the NFC card, in an alternative embodiment, the method further includes:
determining a security index of card information of the NFC card;
and selecting the storage position of the card information of the NFC card from the memory except the eSE and the eSE of the mobile terminal according to the security index of the card information of the NFC card.
Here, the security index of the card information of the NFC card is determined first, that is, the security index of the NFC card is determined according to the security of the NFC card to the user, so as to obtain the security index of the card information of the NFC card, where in determining the security index of the card information of the NFC card, the security index of the card information of the NFC card may be determined according to the confidentiality requirement of the user on the NFC card, and for example, when the security index is classified into a high level and a low level, the security indexes of the bank card, the access card, the digital car key, and the digital identification card may be determined as a high level, and the security indexes of the bus card and the elevator card may be determined as a low level.
In determining the security index of the card information of the NFC card, the security index may be determined in a preset manner by a developer, may be determined based on a preset mapping relationship, may be determined by a preset rule, and may be determined in an interface interaction manner, where the embodiment of the present application is not limited in particular.
After determining the security index of the card information of the NFC card, the storage location of the card information of the NFC card may be selected from the eSE and the memory according to the security index of the card information of the NFC card, that is, according to the characteristic that the security index of the card information of the NFC card is positively correlated with the security index of the storage location of the card information of the NFC card, whether to store the card information of the NFC card to the eSE with a high security index or to the memory with a low security index is determined, so as to ensure the security of the NFC card.
For determining based on the preset mapping relationship, in an alternative embodiment, determining the security index of the card information of the NFC card includes:
And determining the security index of card information of the NFC card based on a preset mapping relation between the NFC card and the security index.
It can be understood that, a mapping relationship between the NFC card and the security index is stored in the electronic device in advance, for example, the security index corresponding to the bank card is high level, and the security index corresponding to the bus card is low level, so that the security index of the NFC card can be determined based on the mapping relationship, and then the storage position can be determined for the card information of the NFC card according to the security index of the NFC card.
In determining the security index of the card information of the NFC card by adopting the interface interaction manner, in an alternative embodiment, determining the security index of the card information of the NFC card includes:
When the configuration interface of the NFC displays the option of the security index of the card information of the NFC card, the security index of the card information of the NFC card is determined in response to the selection operation of the option of the security index of the card information of the NFC card.
It may be appreciated that the configuration interface of NFC is provided in the mobile terminal, where the configuration interface displays options of the security index of the card information of the NFC card, where the options of the security index may include, for example, a high level and a low level, and when the configuration interface of NFC card is displayed on the mobile terminal, the user sends a selection operation of the options of the security index of the card information of the NFC card to the configuration interface, and the mobile terminal determines the security index of the card information of the NFC card in response to the selection operation.
In an exemplary embodiment, the user sends an operation of selecting the option with the high security index to the mobile terminal, so that the mobile terminal receives the operation of selecting the security index of the card information of the NFC card, determines that the security index of the card information of the NFC card is high, and further selects a storage location from the eSE and the memory for the NFC card with the high security index as the eSE.
Therefore, the security index of the NFC card is determined by utilizing interface interaction, so that a user can determine the security index of the card information of the NFC card according to the self requirement by utilizing the interface, the storage position of the card information of the NFC card can be flexibly determined according to the security index set by the user, and the security of the NFC card is improved.
Further, in order to improve the security of the NFC card, in an alternative embodiment, when the security index of the card information of the NFC card includes a high level and a low level, selecting, according to the security index of the card information of the NFC card, a storage location of the card information of the NFC card from the eSE and the memory, includes:
When the security index of the card information of the NFC card is high-grade, determining the storage position of the card information of the NFC card as eSE;
And when the security index of the card information of the NFC card is low, determining the storage position of the card information of the NFC card as a memory.
As can be appreciated, since the eSE is of a high security index and is not easily broken or hacked, the storage location of the card information of the NFC card of a high security index is determined as the eSE, and the storage location of the card information of the NFC card of a low security index is determined as a memory other than the eSE.
In some designs of the operating system, the NFC card stored in the memory other than the eSE may only work in a scene of the mobile terminal lighting up, when the mobile terminal is off, the card simulation function of the NFC card stored in the memory other than the eSE cannot be implemented, so that, in order to enable the NFC card stored in the memory other than the eSE in the mobile terminal to still implement the card simulation function when the NFC card is off, in an alternative embodiment, the method may further include:
when the storage position of the card information of the NFC card is a memory, setting a routing function corresponding to the routing information corresponding to the memory under the screen extinction of the mobile terminal to be available.
It can be understood that when the storage position of the card information for the NFC card is a memory other than the eSE in the mobile terminal, the routing function corresponding to the routing information corresponding to the memory is set to be available under the screen-off condition of the mobile terminal, so that the routing function corresponding to the routing information corresponding to the memory is available under the screen-off condition, and when the mobile terminal receives the read-write signal of the card information for the NFC card during the screen-off condition, the mobile terminal can still respond to the read-write signal of the card information of the NFC card, thereby realizing the card simulation function of the NFC card stored in the memory under the screen-off condition.
In addition, since the eSE is generally available when the mobile terminal is powered off, the card information of the NFC card stored on the eSE is responsive to the read/write signal of the card information of the NFC card, and for the memory other than the eSE, the NFC card stored in the memory other than the eSE of the mobile terminal cannot be used when the mobile terminal is powered off, in order to prevent such card from failing to implement the card emulation function when the mobile terminal is powered off, in an alternative embodiment, the method may further include:
And before the shutdown function of the mobile terminal is executed, determining that the NFC card is an activated card and the storage position of the card information of the NFC card is a memory, and moving the card information of the NFC card from the memory to the eSE of the NFC chip of the mobile terminal.
It should be noted that, the above-mentioned executing the shutdown function of the mobile terminal may be the shutdown function triggered by receiving the shutdown instruction, or may be the shutdown function of the mobile terminal triggered by detecting the electric quantity in the mobile terminal when the detected electric quantity is lower than a preset threshold, which is not limited in particular in the embodiment of the present application.
Here, before the mobile terminal executes the shutdown function, the card information of the NFC card is an activated card, and the card information of the NFC card is stored in a memory other than the eSE, and the card information of the NFC card is moved from the memory to the eSE, so that after shutdown, the card information of the NFC card is stored to the eSE, and the eSE is available under the shutdown condition, so that the card that has been activated is still available under the shutdown condition in a manner of being moved before the shutdown, and thus, the use of the activated NFC card is not affected under the shutdown condition.
Further, in addition to storing the card information of the NFC card into a memory other than the eSE, the card data of the NFC card may also be stored in a memory other than the eSE, and in an alternative embodiment, the method may further include:
selecting a storage position of card data of the NFC card from the eSE and a memory except the eSE of the mobile terminal;
Determining routing information corresponding to a storage position of card data of the NFC card as the routing information of the card data of the NFC card;
and adding the storage position of the card data of the NFC card and the routing information of the NFC card into the configuration information of the NFC card.
It can be understood that the memory location of the card data of the NFC card is selected from the memory other than the eSE and the eSE, the routing information corresponding to the memory location is determined as the routing information of the card data of the NFC card, wherein the card data is generated when responding to the read-write signal of the card information of the NFC card, and the memory location of the card data of the NFC card and the routing information of the NFC card are added to the configuration information of the NFC card, so that the configuration information of the NFC card not only includes the memory location and the routing information of the card information of the NFC card, but also includes the memory location and the routing information of the card data of the NFC card.
In this way, both the card information and the card data of the NFC card can be stored not only in the eSE but also in a memory other than the eSE.
Further, in order to ensure the security of the card data of the NFC card, in an alternative embodiment, selecting a storage location of the card data of the NFC card from the eSE and the memory includes:
Determining a security index of card data of the NFC card;
and selecting the storage position of the card data of the NFC card from the eSE and the memory according to the security index of the card data of the NFC card.
That is, the above-mentioned method for determining the security index of the card data of the NFC card is similar to the method for determining the security index of the card information of the NFC card from the eSE and the memory according to the security index of the card data of the NFC card, and selecting the storage location of the card information of the NFC card from the eSE and the memory according to the security index of the card information of the NFC card, and is not described here again.
For security reasons for card data stored in a memory external to the eSE, in an alternative embodiment, the method may further comprise:
When the storage position of the card data generated when the read-write signal of the card information of the NFC card is responded is a memory, encrypting the card identifier of the NFC card to obtain an encrypted card identifier;
And storing the mapping relation between the encrypted card identifier and the generated card data to a storage position of the generated card data.
It can be understood that, when the storage location of the card data generated in response to the read/write signal of the card information of the NFC card is a memory other than the eSE, that is, the card identifier of the NFC card may be encrypted with respect to the card data stored in the memory other than the eSE, so as to obtain an encrypted card identifier, and then the encrypted card identifier and the card data form a mapping relationship, and the mapping relationship is stored in the memory.
In this way, important card data stored in the memory is prevented from being stolen to affect the security of the corresponding NFC card.
The following describes, by way of example, a method for reading and writing an NFC card in one or more embodiments described above.
Fig. 2 is a schematic structural diagram of an example of an alternative mobile terminal according to an embodiment of the present application, and as shown in fig. 2, the mobile terminal may include a battery 21, a low dropout regulator (Low Dropout Regulator, LDO) 22, a processor 23, a main memory Flash24, and an NFC chip 25, where the NFC chip 25 includes an eSE251.
Based on the above structure, taking the mobile terminal as an example of a mobile phone, a method for dynamically managing storage of an NFC card is provided in this example, so as to alleviate the problem of storage tension. The method comprises the following steps:
For the NFC card, the card information distinguishes between different security levels (corresponding to the above-mentioned security index), which may include a high security level and a low security level, for example, a high security level for a bank card, an access card, a digital car key, and a digital identification card, a low security level for a bus card, and a low security level for an elevator card, and a high security level and a low security level for card data, for example, a high security level for a balance of a card in the card data, and a low security level for a card transaction record.
In this example, card information and card data of a high security level are stored in the eSE of the NFC chip 25, while card information and card data of a low security level are stored in the main memory Flash24 in the mobile terminal.
Taking Android system (Android) as an example, according to the simulation architecture of an NFC card, when NFC is started, a card simulation route needs to be set, for example, when card information is stored in a main memory Flash24 of a mobile terminal, the card simulation route needs to be set as an HCE, and when the card information is stored in an eSE, the card simulation route needs to be set as the eSE.
Taking a partial Log (Log) screenshot when NFC is turned on as an example, fig. 3 is an optional partial Log screenshot when NFC is turned on, as shown in fig. 3, some cards with Route (Route): 00 in fig. 3, some cards with Route: C0 in fig. 3, where Route 00 represents a card analog Route as HCE, and Route C0 represents a card analog Route as eSE.
Here, card information of a low security level is stored in the main memory Flash24 in the mobile phone, and the route of this kind of card information is set to the HCE in the NFC-on process. When a user opens such a low security NFC card for the first time, card information is automatically stored in the mobile phone main memory Flash 24.
It should be noted that, in the setting of Android default, the HCE can only work in the scene of the mobile phone with a bright screen, that is, when the mobile phone with a bright screen, the card information in the HCE route can be used to perform the card swiping action, and when the mobile phone is turned off or turned off, the card information in the HCE route cannot be used. Therefore, the default setting of Android needs to be changed, and the screen-quenching card swiping function under the HCE route is opened, namely, the following bit pos 3 and bit pos 5 are set to be 1.
#bit pos 0=Switch On
#bit pos 1=Switch Off
#bit pos 2=Battery Off
#bit pos 3=Screen off unlock
#bit pos 4=Screen On lock
#bit pos 5=Screen Off lock
The setting of the bit pos 3 and the bit pos 5 to 1 indicates that the HCE routing function is available when the Screen (Screen Off unlock) is unlocked and the HCE routing function is available when the Screen (Screen Off lock) is locked.
It should be noted that, when the mobile phone is turned off, the eSE inside the NFC chip can still be powered by the mobile phone battery, so that the card information with high security level stored in the eSE can still realize the card swiping function. However, when the mobile phone is powered off, the main memory Flash of the mobile phone is not powered on, and the card information stored in the main memory Flash cannot work, so that in order to realize the card swiping function of the NFC card in the power off scene, the card needing to be swiped needs to be moved into the eSE in advance.
In order to implement that the activated NFC card stored in the memory other than the eSE is available in the power-off condition, the method for reading and writing the NFC card described above is described with reference to fig. 4, and fig. 4 is a schematic flow chart of an example of an alternative method for reading and writing the NFC card according to an embodiment of the present application, and as shown in fig. 4, the method for reading and writing the NFC card may include:
S401, detecting electric quantity;
S402, judging whether the electric quantity is lower than a threshold or not, if yes, executing S404, if not, executing S401;
S403, manual shutdown is performed, and S404 is executed;
The method comprises the following two situations that firstly, a user manually shuts down a mobile phone, namely, the user sends out a shutdown operation, and the mobile phone executes S403 manual shutdown, secondly, the mobile phone automatically shuts down when the electric quantity of the mobile phone is too low, namely, the mobile phone is S401 and S402, the electric quantity of the mobile phone is detected firstly, then whether the detected electric quantity is lower than a preset threshold is judged, if the detected electric quantity is lower than the preset threshold, S404 is executed, otherwise, S401 is executed, and electric quantity detection is continued.
S404, judging whether the currently activated card is of a low security level or not, if yes, executing S405, if not, executing S406;
S405, transferring card information from a mobile phone main memory Flash to an eSE;
S406, shutting down.
It can be understood that, before the electronic wallet is powered off, a judging link of the currently activated card in the electronic wallet is added (although a plurality of NFC cards are usually arranged in the electronic wallet, only the selected NFC card is in an activated state, and other NFC cards are in a deactivated state, and only the activated card can be used for swiping the card when the card is swiped), if the currently activated card is an NFC card with a high security level, it indicates that the NFC card is already stored in the eSE, and no additional movement is needed, and the normal power off process is performed.
If the current active card is an NFC card with low security level, indicating that the NFC card is not stored in the eSE, adding a card information moving flow of the NFC card in the shutdown process, moving the card information from the Flash of the mobile phone main memory to the eSE, and then executing the shutdown flow.
In addition, after the mobile phone is started, the card information which is moved into the eSE before is moved back into the main memory of the mobile phone.
In the embodiment, the problem of insufficient storage capacity of eSE in the NFC chip is solved by dynamically managing the NFC card, and card swiping operation under the screen extinction and shutdown scenes is considered, so that user experience is not reduced.
