[0053] It should be noted that the RFID card water controller terminal program upgrade method provided in the embodiment of the present application is generally executed by a server / terminal device, and accordingly, the RFID card water controller terminal program upgrade system is generally set in the server / terminal device.

[0054] It should be understood that Figure 1 The number of terminal devices, networks and servers in the embodiment is only for illustration. Any number of terminal devices, networks and servers may be provided according to implementation requirements.

[0055] Continue to refer Figure 2 , the figure shows a flow chart of a method for upgrading a terminal program of a radio frequency card water controller of the present application, the method comprising the following steps:

[0056] Step 201 , based on a preset data partitioning strategy, the upgrade program maker 2 divides the upgrade program file into multiple data sets.

[0057] In a possible implementation, the preset data partitioning strategy includes performing set optimization processing based on the MCU computing power of the radio frequency card water controller hardware model and the size of the large-capacity contactless CPU card space to complete the partitioning of the preset data, and giving priority to ensuring storage efficiency during the set optimization process.

[0058] In a possible implementation manner, after the upgrade program maker 2 divides the upgrade program file into multiple data sets based on a preset data division strategy, the method further includes:

[0059] After combining multiple data sets with hardware models, spatial distribution, and multiple encryption algorithms, different correlation encryption processes 3 are performed. For the correlation encryption process 3, please refer to Figure 3 .

[0060] In a possible implementation, after combining multiple data sets with hardware models, spatial distribution, and multiple encryption algorithms, and performing different correlation encryption processes 3, the following steps are performed:

[0061] The internal data space of the large-capacity contactless CPU card 1 is initialized by using the RFID radio frequency communication medium 4 , and the encrypted upgrade program file is written into the internal storage space of the large-capacity contactless CPU card 1 .

[0062] In a possible implementation, the multiple data sets are combined with hardware models, spatial distribution, and multiple encryption algorithms to perform different correlation encryption processing 3, please refer to Figure 4 , specifically:

[0063] Step 41, obtaining the hardware model and spatial distribution information of the radio frequency card water controller; wherein the spatial distribution information includes the division of storage areas, the capacity of each area, the read-write properties and the security level.

[0064] Step 42, based on the hardware model computing capability of the RFID card water controller and the security level of the storage area, determine the encryption algorithm of different storage areas of the RFID card water controller. For example, by obtaining the hardware model of the RFID card water controller, the computing capability of the RFID card water controller is obtained, and the performance of the RFID card water controller is evaluated; for high-performance hardware models, a computationally complex and highly secure encryption algorithm such as AES-256 can be adopted; for hardware models with limited resources, a software encryption algorithm can be adopted.

[0065] Step 43, for the encryption algorithm determined for each storage area, combined with the hardware model and data set of the radio frequency card water controller, perform correlation encryption processing 3.

[0066] In a possible implementation, after combining multiple data sets with hardware models, spatial distribution, and multiple encryption algorithms, different correlation encryption processing 3 is performed, which also includes: the encryption permission level of the hardware model of the radio frequency card water controller is prioritized, the encryption permission level of the storage area is second, and the encryption permission level of the capacity size of each area is third.

[0067] In a possible implementation, the encryption algorithm determined for each storage area is combined with the hardware model and data set of the radio frequency card water controller to perform correlation encryption processing 3, which is specifically manifested as follows:

[0068] The identifier of the RFID card water controller hardware model is used to generate a key seed through a hash function, and the key seed and the data set number are used to generate the final associated key through a specific key generation function. In each storage area, the data set is associated and encrypted using a determined encryption algorithm and the generated associated key.

[0069] Step 202 : writing multiple data sets into the internal storage space of the large-capacity contactless CPU card 1 based on a preset sequence.

[0070] In a possible implementation manner, before writing the plurality of data sets into the internal storage space of the large-capacity contactless CPU card 1 based on a preset order, the method further includes:

[0071] The upgrade program maker 2 divides the internal storage space of the large-capacity contactless CPU card 1 into a plurality of independent file units by using the RFID radio frequency communication medium 4, and each file unit has independent security authentication authority.

[0072] For example, security authentication permissions can prevent unauthorized devices or users from accessing specific file units in the large-capacity contactless CPU card 1. For example, in an application scenario involving sensitive information (such as financial transaction data, user privacy data), only a strictly authenticated water controller (through the authentication mechanism between its MCU and the card) can access the file unit that stores the user's account balance information. This is like adding a lock to each file unit, and only devices with the correct "key" (security authentication permissions) can open and read or write data.

[0073] When the upgrade program maker 2 writes multiple data sets to multiple file units of the large-capacity contactless CPU card 1, data can be written to the corresponding file unit only after each file unit is securely authenticated. This can prevent data from being illegally modified during transmission or storage, and ensure the integrity of the data in each file unit. For example, without such security authentication authority, an attacker may tamper with the billing rule file unit of the water controller, resulting in billing confusion.

[0074] In a possible implementation manner, during the process of writing the data set into the large-capacity contactless CPU card 1, the mapping relationship between the file unit and the data set is a one-to-one relationship.

[0075] Step 203 , the radio frequency card water controller exchanges data with the large-capacity contactless CPU card 1 through the RFID radio frequency communication interface 5 , and performs security and uniqueness verification 6 on the large-capacity contactless CPU card 1 .

[0076] Step 204, when the verification is passed, the radio frequency card water controller cyclically traverses each file unit on the large-capacity contactless CPU card 1, and collects the data of each file unit of the large-capacity contactless CPU card 1 into the RAM on the MCU chip of the radio frequency card water controller.

[0077] In a possible implementation, the radio frequency card water controller cyclically traverses each file unit on the large-capacity contactless CPU card 1, and further includes:

[0078] The MCU of the radio frequency card water controller decrypts the data based on the associated encryption combined with the hardware model, spatial distribution, and multiple encryption algorithms to achieve the associated decryption 7 processing of different file units. Please refer to the associated decryption processing 7 process Figure 5 .

[0079] Step 205, after each file unit is read and decrypted, the MCU of the radio frequency card water controller obtains the upgrade program file, stores the upgrade program file in the firmware of the radio frequency card water controller, completes the program upgrade of the radio frequency card water controller terminal, and the radio frequency card water controller can use the new application program.
