Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an encryption method provided in an embodiment of the present application, where the embodiment is suitable for encrypting a login password of a login account, and the method is executed by an encryption device, where the encryption device is implemented by software and/or hardware and is specifically configured in a user side. The user side may be a desktop computer or a mobile phone.
An encryption method as shown in fig. 1, comprising:
s101, responding to the login operation, and generating a session request.
The session request may include a session identifier, session content, and the like.
S102, sending a session request to the server and receiving a target random number fed back by the server.
The target random number may be a random number allocated to the session request.
Specifically, the user side sends a session request to the server side; the server receives the session request, distributes a target random number for the session request according to a preset random algorithm, and feeds the target random number back to the client; the user end receives the target random number for subsequent use.
S103, selecting at least two target encryption algorithms from the at least two candidate encryption algorithms according to the login account and the target random number.
The login account is used for uniquely identifying the user. In the process of one session, one login account corresponds to one target random number. The candidate encryption algorithms can be preset according to business needs, and fixed number of encryption algorithms are set to serve as a selection basis of the target encryption algorithm. The target encryption algorithm may be a candidate encryption algorithm selected according to the login account and the target random number, and is used for encrypting the login password of the login account.
Illustratively, the target hash may be generated according to the login account number and the target random number; and selecting at least two target encryption algorithms from the at least two candidate encryption algorithms according to the target hash.
The target hash may be a character code with a fixed length generated according to the login account and the target random number.
Specifically, based on a preset hash algorithm, generating a target hash according to a login account and a target random number; and selecting at least two target encryption algorithms from the at least two candidate encryption algorithms according to the target hash. The preset hash algorithm is not limited in any way, and can be set by technical staff according to requirements or experience.
In the above example, a method for selecting a target encryption algorithm from candidate encryption algorithms is provided, where a target hash is generated according to a login account and a target random number; and selecting at least two target encryption algorithms from the at least two candidate encryption algorithms according to the target hash. The random generation of the target random number enables the target hash generated according to the login account number and the target random number to have certain regularity, and the situation that the target encryption algorithm cannot be positioned corresponding to the target decryption algorithm in the subsequent data decryption process is avoided.
As an optional manner of the embodiment of the present application, the selecting, according to the target hash, at least two target encryption algorithms from the at least two candidate encryption algorithms may be: determining the target number of a target encryption algorithm according to the byte number of the target hash; and selecting a target number of candidate encryption algorithms from at least two candidate encryption algorithms as target encryption algorithms according to a preset selection sequence.
The number of bytes may refer to the number of bytes of the target hash. The target number may refer to the number of target encryption algorithms. The target number of target encryption algorithms may be equal to the number of bytes of the target hash. The preset selection sequence may be selected according to a certain rule according to the arrangement sequence of the candidate encryption algorithms, for example, according to the arrangement sequence of the candidate encryption algorithms, from front to back, at a fixed interval.
Specifically, the target number of the target encryption algorithm is determined according to the byte number of the target hash; and if the target number of the target encryption algorithms is less than or equal to the number of the candidate encryption algorithms, selecting the target number of the candidate encryption algorithms as the target encryption algorithms from at least two candidate encryption algorithms according to a preset selection sequence. For example, if the number of bytes of the target hash is 5, the target number of the target encryption algorithm is 5; if the number of the candidate encryption algorithms is 6, selecting 5 candidate encryption algorithms from the 6 candidate encryption algorithms as target encryption algorithms according to a preset selection sequence. And if the target number of the target encryption algorithms is larger than the number of the candidate encryption algorithms, circularly selecting the target number of the candidate encryption algorithms as the target encryption algorithms according to a preset selection sequence. For example, if the number of bytes of the target hash is 4, the target number of the target encryption algorithm is 4; if the number of the candidate encryption algorithms is 3; the preset selection sequence is the arrangement sequence of the candidate encryption algorithms, and the arrangement sequence of the candidate encryption algorithms is an encryption algorithm A, an encryption algorithm B and an encryption algorithm C; according to a preset selection sequence, circularly selecting 4 candidate encryption algorithms as a target encryption algorithm, wherein the target encryption algorithm is arranged according to the selection sequence: encryption algorithm A, encryption algorithm B, encryption algorithm C and encryption algorithm A.
According to the technical scheme, the method for selecting the target encryption algorithm from the candidate encryption algorithms is further refined, and the target number of the target encryption algorithm is determined according to the byte number of the target hash; and selecting a target number of candidate encryption algorithms from at least two candidate encryption algorithms as target encryption algorithms according to a preset selection sequence. The number of target encryption algorithms is determined, and the situations of quantity confusion and uncontrollable occurrence are avoided.
In an optional embodiment, the target encryption algorithm corresponding to each byte may be selected from the candidate encryption algorithms according to the hash value of each byte in the target hash. For example, if the hash value is 5, the 5 th candidate encryption algorithm is selected as the target encryption algorithm. If the total number of the candidate encryption algorithms is smaller than the hash value, 1 can be added to the remainder result of the hash value on the total number of the candidate encryption algorithms to obtain a selection serial number, and a target encryption algorithm is selected from the candidate encryption algorithms according to the selection serial number.
And S104, encrypting the login password plaintext of the login account according to each target encryption algorithm to generate a login password ciphertext.
The login password plaintext may refer to a login password corresponding to the login account. The login password ciphertext may be a character code obtained by encrypting a login password corresponding to the login account.
Specifically, according to the preset sequence of each target encryption algorithm, the login password plaintext of the login account is encrypted in a cascade mode to generate a login password ciphertext.
For example, the initial letters of the target encryption algorithms may be arranged in an ascending order, and the login password plaintext of the login account may be encrypted in a cascade manner according to the obtained arrangement order of the target encryption algorithms to generate a login password ciphertext.
For example, according to the selection sequence of the target encryption algorithm, the unused target encryption algorithms may be sequentially selected to encrypt the data to be encrypted, and the encryption result of the target encryption algorithm that is used last time is used as the login password ciphertext. The data to be encrypted of the first target encryption algorithm is a login password plaintext, and the data to be encrypted of other target encryption algorithms is an encryption result of the previous target encryption algorithm.
Specifically, if the selection sequence of the target encryption algorithm is an encryption algorithm C, an encryption algorithm A and an encryption algorithm B, firstly, encrypting a login password plaintext of a login account by using the encryption algorithm C according to the selection sequence of the target encryption algorithm to obtain an encryption result a1; then, encrypting the encryption result a1 by using an encryption algorithm A to obtain an encryption result a2; and finally, encrypting the encryption result a2 by using an encryption algorithm B to obtain a login password ciphertext of the login account.
The operation provides a specific method for encrypting the login password plaintext by using the target encryption algorithm to generate the login password ciphertext, so that the detailed encryption sequence for encrypting the login password plaintext is definitely given, the dynamic encryption of the login password plaintext is realized, and the decryption sequence positioning is conveniently carried out when the login password ciphertext is decrypted subsequently.
As an optional mode of the embodiment of the application, the number of encryption layers of each target encryption algorithm may also be determined, so as to increase the difficulty of cracking the login password ciphertext of the login account.
For example, the number of encryption layers of each candidate encryption algorithm may be set in advance. For example, if the number of encryption layers of each candidate encryption algorithm is preset to be 2 times; candidate encryption algorithms include: encryption algorithm a, encryption algorithm B, and encryption algorithm C. When all candidate encryption algorithms are sequentially used as target encryption algorithms, firstly, encrypting a login password plaintext of a login account for 2 times by using an encryption algorithm A to obtain an encryption result a1; then, encrypting the encryption result a1 for 2 times by using an encryption algorithm B to obtain an encryption result a2; and finally, encrypting the encryption result a2 for 2 times by using an encryption algorithm C to obtain a login password ciphertext of the login account. It should be noted that, the number of encryption layers corresponding to different candidate encryption algorithms may be the same or different.
For example, the number of encryption layers of each target encryption algorithm may be set according to the selection sequence of each target encryption algorithm. For example, if the selection sequence of the target encryption algorithm is an encryption algorithm a, an encryption algorithm B and an encryption algorithm C, the encryption algorithm a is used to encrypt the login password plaintext of the login account for 1 time to obtain an encryption result a1; then, encrypting the encryption result a1 for 2 times by using an encryption algorithm B to obtain an encryption result a2; and finally, encrypting the encryption result a2 for 3 times by using an encryption algorithm C to obtain a login password ciphertext of the login account.
In an optional embodiment, for any target encryption algorithm, the number of encryption layers of the target encryption algorithm may also be determined according to the hash value of the corresponding byte of the target hash when the target encryption algorithm is selected. For example, when the first target encryption algorithm is selected, if the hash value of the first byte in the target hash is 5, the number of encryption layers when the target encryption algorithm is used for encryption is 5. In order to avoid the increase of the calculation amount caused by the overlarge numerical value of the encryption layer number, the maximum encryption layer number can be set, and the numerical value of the encryption layer number determination result is reduced by a mode of taking the balance of the maximum encryption layer number.
And S105, sending a login password ciphertext and a login account to the server.
Specifically, the user side sends a login password ciphertext and a login account of the user to the server side, so that the subsequent server side provides data service for the corresponding user.
The embodiment of the application responds to the login operation and generates a session request; sending a session request to a server and receiving a target random number fed back by the server; selecting at least two target encryption algorithms from the at least two candidate encryption algorithms according to the login account and the target random number; encrypting a login password plaintext of the login account according to each target encryption algorithm to generate a login password ciphertext; and sending a login password ciphertext and a login account to the server. According to the technical scheme, at least two target encryption algorithms are selected from at least two candidate encryption algorithms according to the login account and the target random number issued by the session request, the complexity of the target encryption algorithm determining process and the randomness of the determining result are increased, the cracking difficulty of the login password ciphertext obtained by encrypting the login password plaintext of the login account based on each target encryption algorithm is improved, and the account security corresponding to the session request is improved. Meanwhile, the target encryption algorithm is strongly related to the login account, so that when the login password ciphertext of the login account corresponding to the session request is cracked, the account safety of the login account of other session requests cannot be influenced, and the atomicity of the encryption process is improved.

Fig. 2 is a flowchart of a decryption method provided in the second embodiment of the present application, where the second embodiment is applicable to a case where a login password of a login account is decrypted, and the method is executed by a decryption device, where the decryption device is implemented by software and/or hardware, and is specifically configured in a server.
A decryption method as shown in fig. 2, comprising:
s201, obtaining a login password ciphertext and a login account number sent by the current login session of the user side.
The login session may include a login account, a login password ciphertext, a session identifier, and the like of the user.
S202, determining a target random number according to the session identification of the login session.
Wherein, the session identification is used for uniquely identifying the one-time login session. One session identification corresponds to one target random number.
Specifically, according to the session identifier of the login session, the target random number corresponding to the login session is extracted from the server.
S203, selecting at least two target decryption algorithms from the at least two candidate decryption algorithms according to the target random number and the login account.
The login account is used for uniquely identifying the user. In the process of one login session, one login account corresponds to one target random number. The candidate decryption algorithms may be determined according to the candidate encryption algorithms, and a fixed number of decryption algorithms may be set as a basis for selection of the target decryption algorithm. For example, if the candidate encryption algorithm has encryption algorithm a and encryption algorithm B, then the candidate decryption algorithm has decryption algorithm a 'and decryption algorithm B'. The target decryption algorithm may be a candidate decryption algorithm selected according to the login account and the target random number, and is used for decrypting the login password ciphertext of the login account.
It should be noted that, each candidate decryption algorithm corresponds to the candidate encryption algorithm used in the encryption process, and the number of the candidate decryption algorithms is the same.
Further, a target hash can be generated according to the login account and the target random number; and selecting at least two target decryption algorithms from the at least two candidate decryption algorithms according to the target hash.
The target hash may be a character code with a fixed length generated according to the login account and the target random number.
Specifically, based on a preset hash algorithm, generating a target hash according to a login account and a target random number; and selecting at least two target decryption algorithms from the at least two candidate decryption algorithms according to the target hash. The preset hash algorithm is not limited at all, and can be set by technical staff according to requirements or experience.
According to the technical scheme, the method for selecting the target decryption algorithm from the candidate decryption algorithms is provided, and the target hash is generated according to the login account and the target random number; and selecting at least two target decryption algorithms from the at least two candidate decryption algorithms according to the target hash. According to the session identification of the login session, the target random number is determined, so that the target hash generated according to the login account and the target random number has certain regularity, and the target decryption algorithm is convenient to position the decryption position in the subsequent data decryption process.
Further, the selecting at least two target decryption algorithms from the at least two candidate decryption algorithms according to the target hash may be: determining the target number of a target decryption algorithm according to the byte number of the target hash; and selecting a target number of candidate decryption algorithms from at least two candidate decryption algorithms as target decryption algorithms according to a preset selection sequence.
The number of bytes may refer to the number of bytes included in the target hash. The target number may refer to the number of target decryption algorithms. The target number of target decryption algorithms may be equal to the number of bytes of the target hash. The preset selection sequence may be selected according to a certain rule according to the arrangement sequence of the candidate decryption algorithms, for example, according to the arrangement sequence of the candidate decryption algorithms, from front to back.
Specifically, the target number of the target decryption algorithm is determined according to the byte number of the target hash; and if the target number of the target decryption algorithms is less than or equal to the number of the candidate decryption algorithms, selecting the target number of the candidate decryption algorithms as the target decryption algorithms from at least two candidate decryption algorithms according to a preset selection sequence. For example, if the number of bytes of the target hash is 5, the target number of the target decryption algorithm is 5; if the number of the candidate decryption algorithms is 6, selecting 5 candidate decryption algorithms from the 6 candidate decryption algorithms as the target decryption algorithm according to a preset selection sequence. And if the target number of the target decryption algorithms is larger than the number of the candidate decryption algorithms, circularly selecting the target number of the candidate decryption algorithms as the target decryption algorithms according to a preset selection sequence. For example, if the number of bytes of the target hash is 4, the target number of the target decryption algorithm is 4; if the number of the candidate decryption algorithms is 3; the preset selection sequence is a candidate decryption algorithm arrangement sequence, and the candidate decryption algorithm arrangement sequence is a decryption algorithm A ', a decryption algorithm B ' and a decryption algorithm C '; according to a preset selection sequence, circularly selecting 4 candidate decryption algorithms as target decryption algorithms, and arranging the target decryption algorithms according to the selection sequence: decryption algorithm a ', decryption algorithm B', decryption algorithm C 'and decryption algorithm a'.
According to the technical scheme, the method for selecting the target decryption algorithm from the candidate decryption algorithms is further refined, and the target number of the target decryption algorithm is determined according to the byte number of the target hash; and selecting a target number of candidate decryption algorithms from at least two candidate decryption algorithms as target decryption algorithms according to a preset selection sequence. The number of the target decryption algorithms is determined, and the situations that the number of the target decryption algorithms is mixed up and uncontrollable in the data decryption process are avoided.
In an optional embodiment, the target decryption algorithm corresponding to each byte may be selected from the candidate decryption algorithms according to the hash value of each byte in the target hash. For example, if the hash value is 5, the 5 th candidate decryption algorithm is selected as the target decryption algorithm. If the total number of the candidate decryption algorithms is smaller than the hash value, 1 can be added to the remainder of the total number of the candidate decryption algorithms by the hash value to obtain a selection serial number, and a target decryption algorithm can be selected from the candidate decryption algorithms according to the selection serial number.
And S204, decrypting the login password ciphertext according to each target decryption algorithm to generate a login password plaintext.
The login password ciphertext may be a character code obtained by encrypting a login password corresponding to a login account. The login password plaintext may be a character code obtained by decrypting a login password corresponding to the login account.
Specifically, according to the preset sequence of each target decryption algorithm, the login password ciphertext is subjected to cascade decryption to generate a login password plaintext.
Illustratively, each target decryption algorithm performs cascade decryption on the login password ciphertext according to the ascending order of the initials to generate a login password plaintext.
Illustratively, according to the sequence opposite to the selection sequence of the target decryption algorithm, the unused target decryption algorithm is sequentially selected to decrypt the data to be decrypted, and the decryption result of the last used target decryption algorithm is used as the plaintext of the login password; the data to be decrypted of the first target decryption algorithm is a login password ciphertext, and the data to be decrypted of the other target decryption algorithms are decryption results of the previous target decryption algorithm.
Specifically, if the selection sequence of the target decryption algorithm is decryption algorithm C ', decryption algorithm A ' and decryption algorithm B '; according to the sequence opposite to the selection sequence of the target decryption algorithm, firstly, the login password ciphertext is decrypted by using an encryption algorithm B' to obtain a decryption result B1; then, decrypting the decryption result b1 by using a decryption algorithm A' to obtain a decryption result b2; and finally, decrypting the decryption result b2 by using a decryption algorithm C' to obtain a login password plaintext.
The operation provides a specific method for decrypting the login password ciphertext by using the target decryption algorithm to generate the login password plaintext, so that the detailed decryption sequence for decrypting the login password ciphertext is definitely given, the decryption positioning of each target decryption algorithm is definitely determined, and the dynamic decryption of the login password ciphertext is realized.
As an optional manner of the embodiment of the present application, the number of decryption layers of each target decryption algorithm may also be determined, so as to increase the difficulty of cracking the login password ciphertext of the login account.
For example, the number of decryption layers for each candidate decryption algorithm may be preset. For example, if the number of decryption layers of each candidate decryption algorithm is preset to be 2; the candidate decryption algorithms include: decryption algorithm a ', decryption algorithm B ', and decryption algorithm C '. When all candidate decryption algorithms are sequentially used as target decryption algorithms, firstly, decrypting a login password ciphertext of a login account for 2 times by using a decryption algorithm A' to obtain a decryption result b1; then, decrypting the decryption result B1 for 2 times by using a decryption algorithm B' to obtain a decryption result B2; and finally, decrypting the decryption result b2 for 2 times by using a decryption algorithm C' to obtain a login password plaintext of the login account. It should be noted that, the number of decryption layers corresponding to different candidate decryption algorithms may be the same or different.
For example, the number of decryption layers of each target decryption algorithm may be set according to an order opposite to the selection order of each target decryption algorithm. For example, if the selection sequence of the target decryption algorithm is decryption algorithm a ', decryption algorithm B' and decryption algorithm C ', the decryption algorithm C' is first used to decrypt the login password plaintext of the login account for 3 times, so as to obtain a decryption result a1; then, decrypting the decryption result a1 for 2 times by using a decryption algorithm B' to obtain a decryption result a2; and finally, decrypting the decryption result a2 for 1 time by using a decryption algorithm A' to obtain a login password ciphertext of the login account.
In an optional embodiment, for any target decryption algorithm, the number of decryption layers of the target decryption algorithm may also be determined according to the hash value of the corresponding byte of the target hash when the target decryption algorithm is selected. For example, when the first target decryption algorithm is selected, if the hash value of the first byte in the target hash is 5, the number of decryption layers when decryption is performed by using the target decryption algorithm is 5. In order to avoid the increase of the calculation amount caused by the overlarge numerical value of the decryption layer number, the maximum decryption layer number can be set, and the numerical value of the decryption layer number determination result is reduced by a mode of taking the balance of the maximum decryption layer number.
And S205, feeding back a login page to the user side according to the consistency of the login password plaintext and the login password registered by the login account.
The consistency may mean that the plaintext of the login password is completely consistent with the login password registered in the login account. The login page is used for logging in a certain webpage.
Specifically, comparing a login password plaintext with a login password registered by a login account; if the two are completely consistent, a login page is fed back to the user side; if the login password is not completely consistent with the login password, prompt information is fed back to the user side to prompt the user that the login account or the login password registered by the login account is wrong.
The embodiment of the application acquires the login password ciphertext and the login account number sent by the current login session of the user side; determining a target random number according to the session identification of the login session; selecting at least two target decryption algorithms from the at least two candidate decryption algorithms according to the target random number and the login account; decrypting the login password ciphertext according to each target decryption algorithm to generate a login password plaintext; and feeding back a login page to the user side according to the consistency of the login password plaintext and the login password registered by the login account. According to the technical scheme, based on the login password ciphertext sent by the login session, the login account and the target random number corresponding to the session identifier of the login session, at least two target decryption algorithms are selected from the at least two candidate decryption algorithms to decrypt the login password ciphertext, and therefore the login password plaintext is obtained. The complexity of the target decryption algorithm determination process and the regularity of the determination result are increased, so that the difficulty of decrypting the login password ciphertext based on each target decryption algorithm is improved, and the account safety of the login account corresponding to the login session is improved. Meanwhile, the target decryption algorithm is strongly related to the login account, so that when the login password ciphertext of the login account corresponding to the login session is cracked, the account safety of the login account corresponding to other login sessions is not influenced, and the atomicity of the decryption process is improved.
