The method for preventing the consumable chip from being cracked can be applied to the application environment shown in fig. 2. The anti-cracking method of the consumable chip is applied to an anti-cracking system. The anti-cracking system comprises a terminal 04 and a server 05. Wherein the terminal 04 and the server 05 communicate through a network, as shown in fig. 3, the server 05 includes a database, a classification comparator, a simulation analyzer and an encryption pattern generator, and the terminal 04 includes a screen supporting human-computer interaction. Receiving an encryption request through the terminal 04, wherein the encryption mode request comprises second attribute information of the consumable chip to be encrypted; the server 05 determines the type of the second attribute information, queries a conventional encryption rule of the type, and generates a demand encryption rule different from the conventional encryption rule according to the second attribute information; the encryption pattern generator generates an encryption pattern according to the required encryption rule. The terminal 04 may be, but not limited to, various personal computers, notebook computers, smart phones, and tablet computers, and the server 05 may be implemented by an independent server 05 or a server 05 cluster formed by a plurality of servers 05.
In one embodiment, as shown in FIG. 4, a method for preventing a consumable chip from being broken is provided. This embodiment is mainly exemplified by applying this method to the server 05 as shown in fig. 1. The server 05 obtains a database in which various kinds of conventional encryption rules are stored.
S200, receiving an encryption mode request.
The encryption mode request comprises second attribute information of the consumable chip to be encrypted.
Specifically, the technician inputs the encryption mode request through the terminal 04, and the server 05 receives the encryption mode request transmitted by the terminal 04.
S300, determining the type of the second attribute information, inquiring a conventional encryption rule of the type, and generating a demand encryption rule different from the conventional encryption rule according to the second attribute information.
Specifically, the server 05 determines the type of the second attribute information according to the second attribute information, that is, the type of the consumable chip to be encrypted substantially, queries a conventional encryption rule of the type from the database, and generates a required encryption rule different from the queried conventional encryption rule of the type according to the second attribute information.
And S400, generating an encryption mode according to the required encryption rule.
Specifically, an encryption pattern generator on the server 05 generates an encryption pattern according to the obtained requirement encryption rule.
According to the consumable chip anti-cracking method, the type of the second attribute information is determined through the received second attribute information containing the consumable chip to be encrypted, after the conventional encryption rules of the type of the second attribute information are inquired, the conventional encryption rules are avoided, the requirement encryption rules different from the conventional encryption rules of the type are generated according to the second attribute information, the encryption mode of the consumable chip to be encrypted can be generated according to the requirement encryption rules, the encryption mode of the consumable chip to be encrypted is the encryption mode different from the conventional encryption rules of the consumable chips of the same type, and the problem that the leakage risk is high due to the fact that the existing consumable chip is encrypted by means of artificially setting the encryption information or using a fixed algorithm can be solved. Meanwhile, the difference between the required encryption rule and the conventional encryption rule can be improved, the repeatability brought by artificial habits can be reduced, and the influence of the personal habits of algorithm developers on the encryption mode is avoided to a certain extent, so that the cracking prevention capability of the consumable chip can be improved.
In another embodiment, the step S300 may be performed in the terminal 04. In addition, the encryption mode includes a sequence number generation algorithm and an encryption algorithm.
Further, as shown in fig. 5, the method for preventing the consumable chip from being cracked further includes step S100.
S100, acquiring a conventional encryption rule.
Specifically, the server 05 acquires the regular encryption rules of the various kinds of consumable chips. It should be noted that, when steps S200 to S400 are executed, step S100 need not be performed each time. Also, step S100 and steps S200-S400 may be performed independently, i.e., server 05 may perform steps S200-S400 while performing step S100.
It should be understood that steps S100 and steps S200-S400 may be performed on different servers 05, or may be performed on the same server 05.
Further, the second attribute information includes, but is not limited to, a manufacturer, a model, a color, a capacity, a production time, and a serial number of the consumable chip to be encrypted.
In one possible embodiment, as shown in fig. 6, a schematic flow chart of the sub-steps to step S100 is shown.
S110, acquiring multiple groups of first attribute information of each consumable chip and determining the type of each group of first attribute information.
Wherein, one consumable chip corresponds to one group of first attribute information.
Specifically, the first attribute information of the consumable chip may be entered into the server 05 through the terminal 04. Or in the process of refreshing and burning the consumable chip, the burning device can package the read original chip information of the consumable chip and the burning information into a group of first attribute information and then send the first attribute information to the database of the server 05. When a terminal 04 user uses the printing device, the printing device reads out the first attribute information of the consumable chip and sends the first attribute information to the server 05, and when the printing device detects that the consumable chip is replaced, the printing device reads out the first attribute information of the new consumable chip and sends the first attribute information to the server 05. After the server 05 receives the first attribute information of each consumable chip, the analyzing comparator determines the type of the first attribute information, which is substantially the type of the consumable chip.
And S120, performing algorithm simulation according to the first attribute information of each type to obtain a conventional encryption rule of each type.
Specifically, for each category, the simulation analyzer of the server 05 performs algorithm simulation based on the first attribute information of the category to obtain the normal encryption rule for the category.
S130, storing the conventional encryption rule and the belonged category in a corresponding relationship.
Specifically, after obtaining the conventional encryption rule of each category, the server 05 stores the conventional encryption rule in the database in a corresponding relationship with the category to which the conventional encryption rule belongs.
In the method for acquiring the conventional encryption rule, after the first attribute information of the consumable chip is acquired, the type of the acquired first attribute information is determined, and algorithm simulation is performed according to the first attribute information of each type by taking the type as a unit to simulate the encryption rule of each type of consumable chip so as to acquire the conventional encryption rule of each type.
It should be understood that the server 05 may obtain the first attribute information of each consumable chip continuously or at intervals, and the first attribute information of each consumable chip obtained at each time may be the first attribute information of an original existing consumable chip or the first attribute information of an original non-existing consumable chip. The consumable chips of the same manufacturer and the same model can have different first attribute information due to different production time. And, the more the first attribute information of each kind, i.e. the larger the data size, the greater the probability of simulating the conventional encryption rule with higher accuracy.
It should be noted that, if the conventional encryption rule of the consumable chip is known when the first attribute information of the consumable chip is obtained, the conventional encryption rule of the consumable chip is directly stored, and algorithm simulation is not required to obtain the conventional encryption rule.
With respect to step S110, after acquiring the plurality of sets of first attribute information of each consumable chip, before determining the type of each set of first attribute information, the method further includes:
comparing the first attribute information, and judging whether the same first attribute information exists or not;
if yes, only one group of data is reserved in the same multiple groups of first attribute information.
After the first attribute information is acquired, if the same first attribute information exists, only one group of data is reserved in multiple groups of the same first attribute information, so that the data repetition rate is reduced.
Furthermore, as shown in fig. 7, the method for preventing the consumable chip from being broken further includes step S140.
S140, storing each group of first attribute information and the belonged type in a corresponding relationship.
After the server 05 determines the category of the acquired first attribute information, the server 05 stores each set of the first attribute information and the category thereof in a database in a corresponding relationship.
And in order to increase the amount of the first attribute information in the database, the first attribute information can be continuously acquired, after the first attribute information is acquired, the database compares the acquired first attribute information with the existing first attribute information in the database, if the same data exists, the database only records the log of data storage, and a new space is not opened up to store the group of first attribute information. Therefore, invalid data in the database can be reduced to a certain extent, or malicious uploaded data can be avoided.
It should be noted that step S140 may be executed after step S110 and before step S120.
Optionally, the first attribute information includes, but is not limited to, manufacturer, model, color, volume, time of manufacture, and serial number.
In addition, the method for determining the type of each group of first attribute information in step S110 specifically includes:
and determining the type of each group of first attribute information according to the manufacturer and the model of each group of first attribute information.
And if the manufacturers and the models of the multiple groups of first attribute information are the same, the multiple groups of first attribute information are of the same type, otherwise, the multiple groups of first attribute information are of different types.
In one embodiment, as shown in fig. 8, a flow chart of the sub-step of step S120 is shown.
And S121, aiming at each type, taking the serial number in each group of first attribute information as an output target, taking any number in the residual data of the same group of first attribute information as input, and performing algorithm simulation to obtain a plurality of simulated encryption rules of each type.
And S122, obtaining the conventional encryption rule of each type according to the plurality of analog encryption rules of each type.
In the method, the input of the algorithm simulation is any one of the first attribute information except the serial number, so that the obtained simulated encryption rule can cover various possible encryption rules as much as possible, and the probability of obtaining the accurate encryption rule can be increased to a certain extent.
For S121, specifically, the simulation analyzer performs an algorithm simulation on each group of the first attribute information. Each set of first attribute information obtains one or more analog encryption rules, and each obtained analog encryption rule, the analog analyzer sends the analog encryption rule to the classification comparator. And after receiving an analog encryption rule, the classification comparator compares the analog encryption rule with analog encryption rules of the same type stored in the database, wherein the same type refers to the type of the first attribute information of the analog encryption rule. If the simulation encryption rule consistent with the simulation encryption rule exists in the database, the simulation encryption rule is not stored in the database, otherwise, the obtained simulation encryption rule is stored in the database.
The algorithm used in the algorithm simulation may be a machine learning algorithm or a set algorithm.
In one embodiment, as shown in fig. 9, a flow chart of the sub-step of step S122 is illustrated.
S510, aiming at multiple analog encryption rules of each kind, all the stored first attribute information of the kind is adopted for verification, and the probability value of each analog encryption rule is obtained.
S520, based on a preset threshold, taking the analog encryption rule with the probability value larger than the threshold as the conventional encryption rule of the category.
Specifically, after obtaining a plurality of analog encryption rules of each kind, or after obtaining one analog encryption rule, the server 05 verifies the analog encryption rule of the same kind using all the first attribute information of the same kind, and obtains a probability value of each analog encryption rule.
The verification method may be that, for each analog encryption rule, the input data meeting the analog encryption rule in the first attribute information is used as the input of the analog encryption rule, and after the corresponding analog serial number is obtained, if the analog serial number is consistent with the serial number in the first attribute information, the first attribute information passes verification, otherwise, the verification fails, that is, the verification is not matched. And calculating the ratio between the number of the first attribute information of each analog encryption rule passing the verification and the total number of the first attribute information of the type to which the analog encryption rule belongs, wherein the ratio is the probability value of the analog encryption rule.
The probability value of the simulated encryption rule is larger, which indicates that the simulated encryption rule is more likely to be a common encryption rule of the category to which the simulated encryption rule belongs, so that the conventional encryption rule of each category is determined according to the probability value, and the probability of determining the conventional encryption rule to be a real conventional encryption rule can be increased to a certain extent.
It should be understood that although the various steps in the flowcharts of fig. 4-9 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 4-9 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
In one embodiment, the present application further provides a consumable chip anti-cracking device, as shown in fig. 10, the consumable chip anti-cracking device includes an encryption pattern generation module 08, a data analysis module 07, and a database 06.
