Specific embodiment

In order to make the above objects, features, and advantages of the present application more apparent, with reference to the accompanying drawing and it is specific real Applying mode, the present application will be further described in detail.

The application is described in detail below in conjunction with specific embodiment.

Referring to Fig.1, a kind of step for obscuring embodiment of the method for obscuring method Boolean of Boolean of the application is shown Rapid flow chart, this method can be applied to include transmitting terminal and receiving end system, wherein the transmitting terminal can be terminal or clothes Business device, which may be terminal or server.

In addition, the application can also be applied to the electronic equipment including transmitting terminal and receiving end, at this point, the transmitting terminal and connecing Receiving end can be two functions in electronic equipment, i.e., the transmitting terminal is to send function, which is receiver function, the electronics Equipment can be server or terminal.

In the application, above-mentioned transmitting terminal and receiving end are preset with candidate array, and candidate's array is for characterizing Boolean It is falsity for true value or Boolean, the quantity of above-mentioned candidate's array can be set according to actual needs.Such as, above-mentioned candidate number Group can be two, respectively true value array and falsity array, wherein it is true value that true value array, which can be used for characterizing Boolean, It is falsity that falsity array, which can be used for characterizing Boolean,.

It can specifically include following steps:

Step 101, the transmitting terminal obtains Boolean.

In the embodiment of the present application, receiving end usually sends message to be verified to transmitting terminal, transmitting terminal receive it is above-mentioned After message to be verified, the actual conditions about the message to be verified are obtained, according to the actual conditions of the message to be verified, judgement should Message to be verified it is true and false, to obtain Boolean.

For example, if transmitting terminal is terminal, if receiving end is video server, if the message to be verified is that " transmitting terminal is corresponding The current environment of electronic equipment whether be safe condition ", then terminal is receiving the above-mentioned to be verified of video server transmission After information, the security parameter etc. of itself current environment is obtained, and the case where the security parameter got is designated as safe condition Under, the Boolean which gets is true value, in the case where the security parameter got is designated as precarious position, the terminal The Boolean got is falsity.Above-mentioned example is merely illustrative, and the application is not construed as limiting this.

In embodiments of the present invention, optionally, which can be "true" or "false", alternatively, can be indicated with " 1 " "true" indicates "false" with " 0 ", then, Boolean can also be " 1 " or " 0 ".In embodiments of the present invention, this is not limited specifically It is fixed.

For example, it is directed to above-mentioned example, if in the case that the security parameter that terminal is got is designated as safe condition, the terminal The Boolean got can be true value or be 1.In the case that if the security parameter that terminal is got is designated as precarious position, the end Hold the Boolean got that can be falsity or be 0.

Step 102, the transmitting terminal determines the corresponding target array of the Boolean from the candidate array.

It wherein, include multiple candidate values in the target array.Specifically, above-mentioned candidate values can be arbitrary number Value.In embodiments of the present invention, this is not especially limited.

In the present embodiment, which may include that the corresponding true value array of true value type and falsity type are corresponding Falsity array, and the multiple second candidate numbers for including in multiple first candidate values and falsity array for including in true value array Value is all different, that is to say, that any identical numerical value is not present between two arrays.It can be true value in above-mentioned Boolean In the case of, the true value array for characterizing true value type is determined as the corresponding target array of the Boolean；It is false in above-mentioned Boolean In the case where value, the falsity array for characterizing falsity type is determined as the corresponding target array of the Boolean.

Wherein, the true value array and the falsity array can construct in advance and be separately positioned on transmitting terminal and receiving end.Packet The system for including transmitting terminal and receiving end can also be including preprocessor etc., which can be used for pre-generated true value array With falsity array, and above-mentioned true value array and falsity array are arranged at transmitting terminal and receiving end.

For example, referring to shown in Fig. 2, a kind of Fig. 2 shows the application presets showing for true value array and falsity array It is intended to.Preprocessor can be random to generate true value array and falsity array of the element without intersection by random function etc. in Fig. 2, The true value array can be used for characterizing the Boolean of true value type, which can be used for characterizing the boolean of falsity type Value.Above-mentioned true value array and falsity array can be sent to transmitting terminal and receiving end by preprocessor, by transmitting terminal and reception End stores etc..

Illustratively, if the true value array truelist be [a1, a2 ..., an], the falsity array falselist be [b1, B2 ..., bm], m, n are positive integer, then multiple first candidate values include a1, a2 ..., an, multiple second candidate values packets B1, b2 ..., bm are included, at this point, the true value array for characterizing true value type can be to be somebody's turn to do in the case where above-mentioned Boolean is true value The corresponding target array of Boolean, in the case where above-mentioned Boolean is falsity, the falsity array of characterization falsity type can be The corresponding target array of the Boolean.

Step 103, multiple candidate values that the transmitting terminal includes according to the target array obtain target and obscure value.

In embodiments of the present invention, in the case where above-mentioned Boolean is true value, the true value array of characterization true value type can Think the corresponding target array of the Boolean；In the case where above-mentioned Boolean is falsity, the falsity array of falsity type is characterized It can be the corresponding target array of the Boolean.The multiple candidate values for including according to target array obtain target and obscure value, e.g., One or more candidate values can be randomly selected from above-mentioned target array, obscure value as target, alternatively, can be from above-mentioned One or more candidate values are randomly selected in target array, are carried out simple calculations etc., are obscured value etc. as target, increase The decoding difficulty of interpolater.In embodiments of the present invention, this is not especially limited.

In embodiments of the present invention, the multiple candidate values for including according to the target array obtain target and obscure Value, may include: to select at least one candidate values from multiple candidate values that the target array includes；To it is described at least One candidate values carries out cryptographic calculation, obtains the target and obscures value；Alternatively, the multiple candidates for including from the target array At least one candidate values is obtained in numerical value at random, to obscure value as the target.

Specifically, at least one candidate values first can be randomly selected from above-mentioned target array, to it is above-mentioned at least one Candidate values carry out cryptographic calculation, obtain target and obscure value, increase the decoding difficulty of interpolater.The cryptographic calculation may include one First cryptographic calculation or binary cryptographic calculation etc..Unitary cryptographic calculation may include: to take absolutely at least one above-mentioned candidate values It is worth, takes opposite number, take trigonometric function, negate the operations such as trigonometric function, logic NOT.Binary cryptographic calculation may include: with default Numerical value and at least one above-mentioned candidate values add, subtract, multiplication and division, power, evolution, logarithm, logic and logic or wait operations, It obtains target and obscures value.

For example, continuing to be illustrated by taking the example in step 102 as an example, the case where the target array is the true value array Under, at least one candidate values, such as a2 can be selected from true value array truelist, a2 can be taken to opposite number-a2, obtained Target obscures value；The target array be falsity array in the case where, can be randomly choosed from falsity array falselist to Bn can be taken opposite number-bn, obtain target and obscure value by few candidate values, such as bn.

The application can include multiple wait select to obtain at least one candidate values in numerical value at random from target array, with Value is obscured as target, in this way, increasing the decoding difficulty of interpolater.Illustratively, continue by taking the example in step 102 as an example into Row explanation can obtain candidate at random in the case where the target array is the true value array from true value array truelist Numerical value such as obscures value for a2 as target to obscure value as target；It, can in the case where the target array is falsity array To obtain candidate values at random from falsity array falselist, to obscure value as target, such as obscure bn as target Value.

In this way, can be obscured by the candidate values Boolean, so that interpolater is not easy to decode to before obscuring Boolean in the case where Boolean is true value, " 1 " is set by Boolean, in boolean in addition, due in the prior art In the case that value is falsity, " 0 " is set by Boolean, and after being obscured according to the acquisition of multiple candidate values in the application Boolean increases interpolater couple so that the target that transmitting terminal is sent in the next steps, which obscures value, has uncertainty Target obscures the decoding difficulty of value.

Step 104, the target is obscured value and is sent to the receiving end by the transmitting terminal.

In embodiments of the present invention, transmitting terminal and receiving end can communicate, and above-mentioned target is obscured value and sent out by transmitting terminal It send to receiving end.

Step 105, value determining target array from the candidate array is obscured according to the target in the receiving end.

Wherein, the candidate array of the receiving end and Sender side Storage is identical array, and therefore, this step can pass through true value Multiple second candidate values for including in multiple first candidate values and falsity array for including in array, determine the target Array.

Specifically, such as, if target obscures value and directly randomly selects to obtain from above-mentioned target array, if target is obscured Value is the first candidate values, and target array is true value array, if it is the second candidate values that target, which obscures value, target array is falsity Array.

Such as, for the example in step 103, if target is obscured value a2 and is directly obtained at random from true value array truelist It takes, then, receiving end judges to show that target obscures value a2 as the first candidate values, then, true value array is target array.

If it is also to have carried out cryptographic calculation after randomly selecting from above-mentioned target array that target, which obscures value,, above-mentioned Before step 105, it can also include: to obscure value to the target operation is decrypted, obtain candidate values；It is described according to Target obscures value and determines target array from the candidate array, may include: according to the candidate values from the candidate number Target array is determined in group.

That is, if it is also to have carried out cryptographic calculation after randomly selecting from above-mentioned target array that target, which obscures value, It needs first to obscure value to above-mentioned target and carries out decryption operation corresponding with above-mentioned cryptographic calculation, if the candidate number that decryption operation obtains Value is the first candidate values, then, target array is true value array, if the candidate values that decryption operation obtains are the second candidate number Value, target array are falsity array.Above-mentioned decryption operation can be the inverse operation with above-mentioned cryptographic calculation.

For example, continuing to be illustrated by taking the example in step 103 as an example, if it is from true value array that target, which obscures value-a2, In truelist at random obtain after carried out the cryptographic calculation for taking opposite number, then receiving end first to the target obscure value-a2 into Row takes the decryption operation of opposite number, obtains candidate values a2, receiving end judge to obtain candidate values a2 as the first candidate values, Then, true value array is target array.

Step 106, the receiving end determines the Boolean that the transmitting terminal is got according to the target array.

Wherein, since true value array corresponds to true value type, falsity array corresponds to falsity type, therefore, in the target array In the case where for true value array, it can determine that Boolean type is true value type, in the case where the target array is falsity array, It can determine that Boolean type is falsity type.

Using the above method, transmitting terminal and receiving end are preset with candidate array；Transmitting terminal obtains Boolean；Transmitting terminal from The corresponding target array of Boolean is determined in candidate array；It include multiple candidate values in target array；Transmitting terminal is according to target Multiple candidate values that array includes obtain target and obscure value；Target is obscured value and is sent to receiving end by transmitting terminal；Receiving end root Value is obscured according to target, and target array is determined from candidate array；Receiving end determines the cloth that transmitting terminal is got according to target array Value of.To sum up, the application obscures Boolean in such a way that array is searched, and obtains target and obscures value, relative to existing In technology, the result of simple operation is still practical Boolean 0 or 1 only for two kinds of results, and above-mentioned target obscures the value of value Range is big, value possibility is more, makes the more difficult decoding of interpolater obscure value to above-mentioned target first and represents boolean's classification, even if usurping The person's of changing decoding obscures value to above-mentioned target and represents boolean's classification, since the value that target obscures value is not limited to 0 or 1 two kind, In the case where there is no target to obscure value and practical Boolean corresponding relationship, so that interpolater obscures value according to above-mentioned target, it is more difficult to The practical Boolean before obscuring is decoded, so that the more difficult Boolean to after obscuring is distorted, and then receiving end is improved and obtains The accuracy for the Boolean got.

Referring to Fig. 3, show the first Boolean of the application obscure method Boolean obscure the optional implementation of method The step flow chart of example is applied to transmitting terminal, and in the application, above-mentioned transmitting terminal is preset with candidate array, which is used for Characterization Boolean is true value or Boolean is falsity, and the quantity of above-mentioned candidate's array can be set according to actual needs.Such as, Above-mentioned candidate's array can be two, can be respectively true value array and falsity array, wherein true value array can be used for characterizing Boolean is true value, and it is falsity that falsity array, which can be used for characterizing Boolean,.

It can specifically include following steps:

Step 201, Boolean is obtained.
