Detailed Description

Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments may, however, be embodied in many different forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art.

Furthermore, the described features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.

One skilled in the relevant art will recognize, however, that the subject matter of the present application can be practiced without one or more of the specific details, or with other methods, components, devices, steps, and so forth. In other instances, well-known methods, devices, implementations, or operations have not been shown or described in detail to avoid obscuring aspects of the application.

The specific meaning of the above terms in the present disclosure can be understood by those of ordinary skill in the art as appropriate.

Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.

The block diagrams shown in the figures are functional entities only and do not necessarily correspond to physically separate entities. I.e. these functional entities may be implemented in the form of software, or in one or more hardware modules or integrated circuits, or in different networks and/or processor means and/or microcontroller means.

The flow charts shown in the drawings are merely illustrative and do not necessarily include all of the contents and operations/steps, nor do they necessarily have to be performed in the order described. For example, some operations/steps may be decomposed, and some operations/steps may be combined or partially combined, so that the actual execution sequence may be changed according to the actual situation.

After the relevant products of the washing machine are on the market, the software of the washing machine usually needs to be optimized and upgraded correspondingly for market feedback and the like in the whole market period, and the optimized and upgraded contents are usually optimized for user experience or parameter classes such as flow, time, display and the like and have no relation with the aspect of safety certification.

Because the storage mode of the existing washing machine is an integral storage mode, namely all parameters are stored in the same area, the safety-related content of the washing machine is not independent. Therefore, if the washing machine needs to be authenticated safely, the obtained checksum, version and the like are authenticated by the authentication mechanism, and at this time, if the washing machine needs to be optimized and upgraded for the content which is irrelevant to the safety (such as the running time of different running programs of the washing machine and the like), the checksum of the whole software also changes, so that the washing machine needs to be authenticated safely again.

It should be noted that checksum (checksum) refers to a sum used for verifying a group of data items at a destination in the data processing and data communication fields. It is usually expressed in hexadecimal form as a numerical system. The integrity and accuracy of data can be ensured in communication, especially long-distance communication.

Fig. 1 schematically shows a flowchart to which an embodiment of the present invention is applied, and referring to fig. 1, the processing method of the washing machine at least includes steps S110 to S120, which are described in detail as follows:

step S110, an address range of the memory module is obtained.

In one embodiment, the address range of the memory module is determined according to the memory space, for example, 256Kbytes, which is converted into a 16-system address range of 0x00000000 to 0x0003 FFFF.

Step S120, dividing the storage module into a safety region and an adjustment region which are independent of each other according to the address range of the storage module, wherein the safety region stores safety evaluation parameters of the washing machine, and the adjustment region stores other parameters except the safety evaluation parameters in the washing machine; when the parameters stored in the adjusting area are updated, the security evaluation parameters stored in the security area do not need to be checked.

According to the address range of the memory module described in the above embodiments, the memory module is divided into the security area and the adjustment area, which are independent of each other, for example, the address range of the security area is 0x0003D8E0 to 0x0003FFFB, which stores the security evaluation parameters of the washing machine, and the address range of the adjustment area is 0x00000000 to 0x0003D8DF, which stores the parameters of the washing machine except the security evaluation parameters. For example, the address range of 0x0003FFFC to 0x0003FFFF is not allocated to a secure area or an adjustment area, and may be used to store a checksum, or may be directly used as a hole address for debugging software.

It should be noted that the parameters mentioned in the present application include the parameters themselves and the logic decisions related to the parameters.

In an embodiment, after the storage module is divided into the mutually independent security area and the adjustment area, the security evaluation parameter stored in the security area can be independently checked to obtain a checksum of the security area, and the checksum of the security area independent check can be stored in the address 0x0003 FFFC.

The checksum can be used to determine whether software is modified, after the embedded software is compiled to generate a binary-format programmed file (e.g., a file in HEX format), the entire programmed file is calculated according to a predetermined rule, and finally a number from one byte to several bytes is generated, which is the checksum. If the software is modified, the number of checksums will also change, and checksums are also what is needed for authentication. Therefore, if the safety evaluation parameter of the safety area is updated, the checksum is also changed by checking the safety evaluation parameter of the safety area to obtain the checksum. However, if only the contents of the adjustment area are updated, the security evaluation parameters stored in the security area do not change, and the checksum does not change.

It should be noted that there are many verification methods, and the checksums generated by different verification methods are different, so after one verification method is selected, if verification is needed again, the verification method should be selected to generate the checksum.

In an embodiment, the check method is a Cyclic Redundancy Check (CRC) method, and may specifically be a CRC16 bit check method.

It should be noted that Cyclic Redundancy Check (CRC) is a channel coding technique for generating a short fixed bit check code according to data such as a network data packet or a computer file, and is mainly used to detect or check errors that may occur after data transmission or storage. It uses the principle of division and remainder to detect the error.

According to the processing method of the washing machine, the storage module is divided into the mutually independent safe area and the adjustment area, so that the safety evaluation parameters can be mutually independent from other parameters, only the safety evaluation parameters stored in the safe area are authenticated during initial safety authentication, and when other parameters need to be updated, the parameters stored in the safe area do not need to be verified and authenticated again as long as the updating of the safety evaluation parameters is not involved.

Fig. 2 schematically shows a flowchart of an embodiment of step S120, and referring to fig. 2, in step S120, dividing the memory module into the mutually independent security area and adjustment area according to the address range of the memory module at least includes steps S121 to S123.

Step S121, obtaining the storage capacity required by the storage of the security assessment parameters;

step S122, determining the address range of the safety area according to the storage capacity;

step S123, determining an address range of the adjustment area based on the address range of the storage module and the address range of the secure area.

For example, if the capacity required for storing the security evaluation parameter is 70KBytes, the address range of the secure area may be determined to be 0x00000000 to 0x00011800 according to the storage capacity 70KBytes through hexadecimal conversion, and the address range of the secure area is subtracted from the address range of the storage module to obtain the address range of the adjustment area, which is 0x00011801 to 0x0003FFFF, where it is to be noted that a part of the address range of the adjustment area may be selected as required to store the checksum or be used as a hole address.

In one embodiment, the security assessment parameters include microelectronic inspection parameters.

The microelectronic inspection refers to the necessary inspection of the ClassB part in authentication, and generally includes ROM (read only memory) inspection, RAM (random access memory) inspection, clock inspection, interrupt inspection, register inspection, stack inspection, and so on.

For example, microelectronic inspection parameters such as ROM inspection in microelectronic inspection can include ROM inspection address range 0x0003D8E0 ~ 0x0003FFE 0.

For example, in the RAM inspection in the microelectronic inspection, the microelectronic inspection parameters can include the RAM address range of 0x1FFFC 000-0 x20003 FFF.

The microelectronic inspection parameters may include a clock count of 50000 and a clock skew threshold of 50-150, for example, for clock inspection in microelectronic inspection.

And also for example, interruption check in microelectronic inspection, the microelectronic inspection parameter may include a count of number of interruption checks of 10000, wherein the threshold value of interruption deviation may be 250-750.

The microelectronic inspection parameters in the above embodiments are security evaluation parameters that must be stored in the security area, and the specific values may vary with different requirements and may also vary with different main control chips.

In one embodiment, the security assessment parameters further comprise one or more of door lock detection parameters, water level sensor detection parameters, and variable check detection parameters.

The door lock detection parameters can include that the door lock of the washing machine can only be in a closed state when the washing machine runs at a high speed; the water level sensor detecting parameter may include detecting whether a water level sensor of the washing machine is abnormal.

In one embodiment, the variable check detection parameters include one or more of a water level value variable parameter, a temperature value variable parameter, and a rotation speed value variable parameter.

The water level value variable parameter is used for representing and recording parameters of variables of the water level, for example, AAA is used for representing a value of the detected water level, and the water level value variable is assigned, for example, the value of the water level may be 150, or may be other values such as 100 or 0, which are all changed in real time, and the present application is not limited specifically.

The temperature value variable is similar to the water level value variable, and is used for representing and recording the current temperature value of the water in the washing drum of the washing machine, and the values are also changed in real time.

The variable of the rotation speed value is similar to the variable of the water level value, is used for representing and recording the current rotation speed value in the washing drum of the washing machine, and the values are also changed in real time.

In one embodiment, the other parameters stored in the adjustment area include one or more of a key detection parameter, a display parameter, and a washing program operation parameter.

The washing program operation parameters may include a default time for each washing program to operate. The washing machine can also comprise a rotation-stop ratio (the rotation-stop ratio refers to the ratio of the operation time of the washing drum to the stop time when the washing machine operates) when each washing program operates, for example, the rotation-stop ratio can be set to 20 seconds, 5 seconds, 20 seconds and 5 seconds when the washing machine operates, and the rotation-stop ratio is 20: 5. The washing program operation parameters may also comprise a default rotation speed when the washing program is operated, for example, the default rotation speed when the washing machine is washing is 55r/min (r/min is rpm), and the maximum rotation speed when the washing machine is dehydrating is 1600 r/min. It should be noted that, in the present application, the parameters of the adjustment area are not specifically limited, and any parameter that is not related to the safety evaluation may be placed in the adjustment area.
