Description
Technical Field
The present application relates to the field of computer technologies, and in particular, to an information encryption method and apparatus, and an electronic device.
Background
Anonymous traceability is a core advantage of blockchain technology. Under the environment of complete open source, the user can safely manage the own account, execute the intelligent contract trusted by the user, and can also re-encrypt the anonymous information, and simultaneously ensure that the encrypted information is still operable.
In a real application, the interaction between the blockchain and the user is a wallet, and particularly, in an operation interface of a mobile terminal, the user only has a limited number of possible methods for generating encryption parameters: 1) inputting by a keyboard; 2) gesture sliding; 3) inputting voice; 4) and (5) face recognition.
The user interface of the existing encryption product usually inputs a secret key by inputting a password, inputting a fingerprint or other contact modes, and this scenario is usually applicable to a scenario that does not require a user to customize an encryption function. However, in such a scenario, the risk of key leakage, such as snooping by others and screen recording, exists in the process of inputting the password by the user, and great potential safety hazard exists.
And if a user self-defines an encryption function, for example, an intelligent contract is encrypted in a isomorphic encryption mode, the system can only recommend the user default encryption function, which greatly increases the possibility that the encrypted information of the user is reversely cracked.
Therefore, how to improve the security level of the user encrypted information and avoid password leakage and reverse cracking becomes a technical problem to be solved urgently.

It is understood that the main subject of the method is the terminal device, which is only an exemplary illustration, and should not be construed as a limitation of the method.
Specifically, the key generation method of the present invention includes: firstly, generating an initial curve on a screen, wherein the initial curve comprises at least one continuous curve segment; then, the adjustment operation of the user on the at least one curve segment can be received, and the corresponding curve segment is adjusted according to the adjustment operation; determining an encryption function set according to the adjusted at least one curve segment, wherein the encryption function set comprises at least one encryption function, and one curve segment corresponds to one encryption function; and finally, encrypting the information to be encrypted according to the encryption function set.

The following describes in detail an implementation process of the information encryption method, by taking an implementation flow diagram of the information encryption method shown in fig. 1 as an example, and the implementation process includes:
generating an initial curve on a screen, wherein the initial curve comprises at least one continuous curve segment;
optionally, in order to increase the complexity of information encryption and increase the security level of the encrypted information, the initial curve generated on the screen by one or more embodiments of the present specification may include one or more intermediate points, where the intermediate points enable a user to move the position of the initial curve through a preset operation to change the shape of the initial curve, so as to customize the set of encryption functions corresponding to the initial curve. Then, an initial curve is generated on the screen, including:
generating two end points on a screen and generating at least one intermediate point between the two end points;
and sequentially connecting two adjacent points on the screen according to a preset mode to obtain at least one continuous curve section, wherein the at least one continuous curve section forms an initial curve.
Fig. 2(a) is a schematic diagram of an initial curve generated on a screen in an embodiment of the present disclosure. In fig. 2(a), the initial curve includes two end points (i.e., point a and point B) and 3 intermediate points (i.e., point M1, point M2, and point M3).
It should be understood that in order to connect two adjacent points on the screen, i.e. to connect AM1, M1M2, M2M3 and M3B in sequence in fig. 2(a), to form curve segments AM1, M1M2, M2M3 and M3B, there is a corresponding initial function between the two adjacent points in the embodiment of the present specification, the initial function is taken from a preset function library, and the initial function determines the shape of the curve segment; alternatively, two adjacent points may be randomly connected. Then, connecting two adjacent points on the screen in sequence according to a preset mode includes:
determining initial functions respectively corresponding to two adjacent points on the screen, and sequentially connecting the two adjacent points on the screen based on the initial functions; or
Two adjacent points on the screen are randomly connected.
As shown in fig. 2(a), assuming that two adjacent points, point a to point M1, correspond to a cryptographic function E1(X), point a and point M1 may be connected based on the cryptographic function E1 (X); assuming that two adjacent points from the point M1 to the point M2 correspond to a cryptographic function E2(X), the point M1 to the point M2 may be connected based on the cryptographic function E2 (X); assuming that two adjacent points from the point M2 to the point M3 correspond to a cryptographic function E3(X), the point M2 and the point M3 may be connected based on the cryptographic function E3 (X); assuming that two adjacent points, i.e., the point M3 and the point B, correspond to a cryptographic function E4(X), the point M3 and the point B can be connected based on the cryptographic function E4 (X).
And step 120, receiving an adjustment operation of the user on at least one curve segment, and adjusting the corresponding curve segment according to the adjustment operation.
As shown in fig. 2(a), after the user sees the initial curve (the curve between the point a and the point B shown in fig. 2 (a)) shown on the screen and the middle points M1, M2, and M3 of the initial curve, the positions of the middle points M1, M2, and M3, such as the positions of the middle points M1, M2, and M3, may be moved upward, downward, leftward, or rightward. After receiving the user's position adjustment operations for the middle points M1, M2, and M3 of the curve, the curve segment between the point a and the point B may be adjusted according to the user's adjustment operations.
Assume that the curve generated after the user makes an adjustment is as shown in fig. 2 (b). The curve is composed of a curve segment between point a to point M1 ', a curve segment between point M1' to point M2 ', a curve segment between point M2' to point M3 ', and a curve segment between point M3' to point B.
it should be understood that, since the shape of the adjusted curve segment is changed, and the corresponding function between two adjacent points in the curve segment is also changed correspondingly, the set of cryptographic functions is determined according to at least one adjusted curve segment, including:
determining an encryption function corresponding to each adjusted curve segment according to coordinates of the initial point and the end point of each adjusted curve segment in a pre-established coordinate system and a corresponding initial function;
and obtaining an encryption function set based on the adjusted encryption function corresponding to each curve segment.
Optionally, to implement isomorphic encryption, in the embodiment of the present specification, all curve segments after adjustment are monotonically continuous, and curves composed of all curve segments after adjustment are also monotonically continuous.
Isomorphic encryption is a mathematical mapping method, assuming that the encryption function is denoted as E, the following conditions are satisfied:
E(A op B)＝E(A)op E(B)；
that is, after the result of the operation on the ciphertext is decrypted, as is the result of the operation on the plaintext:
E -1 (E(A op B))＝A op B。
the op represents operation modes such as addition, subtraction, multiplication and division or character string splicing.
Here, since all the curve segments after adjustment are monotonously continuous and the curves composed of all the curve segments after adjustment are also monotonously continuous, the set of cryptographic functions determined from the curve segments after adjustment is also monotonously continuous. Any combination of numbers (X1, X2..) is input, ciphertext (E (X1), E (X2)) is calculated from the set of cryptographic functions, and the ciphertext may subsequently be output to an application. Since E is monotonic, the ciphertext is also persistent. Ciphertext continuation means that ciphertext keeps the same order as plaintext, and if X1< X2< X3 >, then E (X1) < E (X2) < E (X3) <.
And 140, encrypting the information to be encrypted according to the encryption function set.
Optionally, in order to avoid the problem that the set password is leaked due to the fact that the user is peeped or recorded on the screen by others in the password setting process, the information to be encrypted in the embodiment of the description may include the plaintext password to be encrypted;
according to the encryption function set, encrypting the information to be encrypted comprises the following steps:
and encrypting the plaintext password to be encrypted according to the encryption function set to generate a secret key.
At the moment, the encryption function set generated by the background cannot be snooped, so that even if a plaintext password is leaked, a secret key cannot be leaked, and the safety is improved.
Of course, the encryption application scenario of the embodiment of the present invention is not limited to encrypting a plaintext password, and may also be applied to any scenario that requires encryption, for example, encrypting confidential data using an encryption function set.
Optionally, the plaintext cipher to be encrypted includes a plurality of numbers or characters, and one encryption function corresponds to one value range respectively;
encrypting a plaintext password to be encrypted according to an encryption function set, comprising:
determining an encryption function corresponding to the value ranges of a plurality of numbers or characters in the plaintext password to be encrypted from the encryption function set based on the value range corresponding to each encryption function in the encryption function set;
and encrypting the plurality of numbers or characters in the plaintext password to be encrypted based on the encryption function corresponding to the value ranges of the plurality of numbers or characters in the plaintext password to be encrypted.
Alternatively, the plaintext cipher to be encrypted may be a plaintext cipher consisting of a plurality of digits, such as a six-digit plaintext cipher "312645" which may consist of digits 1, 2, 3, 4, 5, 6; a plaintext cipher which may also consist of a plurality of letters, such as a six-digit cipher "back", which may consist of letters a, b, c, d, e, f; a plaintext cipher, which may also consist of letters and numbers, such as a six-digit cipher "a 2c1b 3", which may consist of numbers 1, 2, 3 and letters a, b, c; a plaintext cipher may also consist of letters, numbers and underlines, such as a six-digit cipher "12 _ cba" which may consist of numbers 1, 2, letters a, b, c and underline _ for example.
It should be understood that, since the value ranges of the one or more encryption functions corresponding to the adjusted curve segments are often the value ranges of numbers, in order to facilitate a user to set a plaintext password containing letters or underlines, embodiments of the present specification may preset a mapping relationship table between letters and underlines and numbers, for example, an underline may be set to correspond to a number 10, a letter a corresponds to a number 11, a letter b corresponds to a number 12, and so on.
It should be understood that the above-listed components and numbers of digits of the plaintext password to be encrypted are merely exemplary illustrations, and in practical applications, the numbers and specific contents of letters, numbers and underlines included in the plaintext password to be encrypted may be specifically set according to the memory habits and the operation behaviors of the user, which is not specifically limited by one or more embodiments of the present specification.
Assuming that a plaintext cipher to be encrypted contains a plurality of numbers "312645", taking a curve segment shown in fig. 2(B) as an example, the curve segment includes four segments, where a value range of an encryption function corresponding to a curve segment between a point a and a point M1 'is [ x0, x 1' ], a value range of an encryption function corresponding to a curve segment between a point M1 'and a point M2' is [ x1 ', x 2' ], a value range of an encryption function corresponding to a curve segment between a point M2 'and a point M3' is [ x2 ', x 3' ], and a value range of an encryption function corresponding to a curve segment between a point M3 'and a point B is [ x 3', x4 ].
Then, for the plaintext cipher "312645" to be encrypted, it is first determined which range [ X0, X1 '], [ X1', X2 '], [ X2', X3 '] and [ X3', X4] the "3" belongs to, and assuming that "3" belongs to [ X1 ', X2' ], it may be determined that the encryption function corresponding to "3" is the encryption function E2 '(X) corresponding to the curve segment between the point M1' and the point M2 ', and the encryption processing on "3" based on the encryption function results in E2' (3);
then determining which range of [ X0, X1 '], [ X1', X2 '], [ X2', X3 '] and [ X3', X4] that "1" belongs to, assuming that "1" belongs to [ X0, X1 '], determining that the encryption function corresponding to "1" is the encryption function E1' (X) corresponding to the curve segment between the point a and the point M1 ', and performing encryption processing on "1" based on the encryption function to obtain E1' (1);
then, it is determined which range of [ X0, X1 '], [ X1', X2 '], [ X2', X3 '] and [ X3', X4] that "2" belongs to, and assuming that "2" belongs to [ X1 ', X2' ], it is determined that the encryption function corresponding to "2" is the encryption function E2 '(X) corresponding to the curve segment between the point M1' and the point M2 ', and the encryption processing is performed on "1" based on the encryption function, so that E2' (2) is obtained;
by analogy, the encryption functions corresponding to "6", "4" and "5" and the keys processed based on the corresponding encryption functions are determined in sequence, and are assumed to be E4 ' (6), E3 ' (4) and E3 ' (5); it can be determined that the plain text password "312645" is a combination of keys E2 '(3), E1' (1), E2 '(2), E4' (6), E3 '(4), and E3' (5) obtained through encryption processing of the corresponding encryption function.
Optionally, in an implementation, a component packaged by using the method provided in an embodiment of the present specification may serve as a plug-in for a target application, where the plug-in may be used for setting a login password, a payment password, and the like of the target application, and inputting the login password and the payment password, and then after encrypting information, the method further includes:
and performing at least one of a login operation, a payment operation, and a transfer operation based on the encrypted information.
Taking a setting scenario of a password such as a login password and a payment password of a target application as an example, assuming that a user registers an account of the target application after downloading the target application, at this time, the user is often required to manually set the password such as the login password and the payment password of the target application. In this case, in the setting interface of the password such as the login password or the payment password of the target application, a default shape of the curve provided by the system may be displayed for the user, as shown in fig. 2(a), the starting point of the encryption curve is point a, the end point of the encryption curve is point B, and a plurality of points exist between point a and point B, so that the user can slide up, down, left and right. The user can change the shape of the default curve by sliding the points A and B up and down and left and right, so as to realize the self-defined setting of the encryption function corresponding to the curve segment.
After the user adjusts the shape of the curve segment, a confirmation operation may be performed on the curve segment, for example, two buttons "confirm" and "cancel" may be included in the display interface of the curve segment. When the user is detected to click the 'confirm' button, the user is indicated to confirm the shape of the curve segment, and the setting of the shape of the curve segment is completed. At this time, the curve segment may be saved, so that the curve segment is called to perform an encryption operation on the plaintext password input by the user when the user performs a login or payment operation next time.
After the user sets the shape of the curve segment, the set plaintext password can be input in the password setting input box, and it should be understood that the plaintext password is not the actual login password or payment password of the target application, so even if the plaintext password is snooped or recorded by others, the user cannot log in the target application or pay through the target application based on the plaintext password.
The method provided by the embodiment of the specification can determine the encryption function in the background through the shape of the curve segment, the encryption function is not displayed on a screen, and specific parameters cannot be recovered even if the encryption function is snooped or recorded, so that the encryption security level is improved, the encryption function is determined through the curve segment adjusted by a user, the randomness is high, and the difficulty of reverse cracking is further improved.
