By generating the first user interface, a user can set a plurality of keywords on the first user interface conveniently, wherein each keyword is used for determining the encrypted field.

S110b, acquiring a plurality of keywords input by a user in the first user interface, and generating a preset encryption field according to the keywords.
For example, if the user inputs two keywords, namely "user name" and "mobile phone number" in the first user interface, the preset encryption fields are the "user name" field and the "mobile phone number" field.
Referring to fig. 4, fig. 4 is a schematic flowchart of a data table encryption method according to another embodiment of the present application. In this embodiment, before the step S110, the method includes a step S110c and a step S110d.
And S110c, generating a second user interface, wherein the second user interface comprises a plurality of second parameter input areas and third parameter input areas associated with the second parameter input areas, each second parameter input area is used for a user to input a keyword, the keyword is used for determining an encrypted field, each third parameter input area is used for the user to input an encryption index, and the encryption index is used for determining the encryption level of the field.
And generating a second user interface to facilitate the user to set a plurality of keywords on the second user interface, wherein each keyword is used for determining the encryption field, and an encryption index is set for each keyword. For example, the user may set two keywords, which are "user name" and "mobile phone number", respectively, on the second user interface, and correspondingly set the encryption indexes to be "1" and "2", respectively.
S110d, obtaining a plurality of keywords and a plurality of encryption indexes input by a user on the second user interface, and generating a preset encryption index according to the plurality of keywords, wherein the plurality of keywords are associated with the plurality of encryption indexes.
For example, if the user inputs two keywords, which are "user name" and "mobile phone number" respectively, on the second user interface, the preset encryption fields are the "user name" field and the "mobile phone number" field, and the encryption indexes of the corresponding encryption fields are "1" and "2" respectively.
Referring to fig. 5, fig. 5 is a schematic flow chart of a data table encryption method according to another embodiment of the present application. In this embodiment, after the step S110d, the method further includes a step S110e and a step S110f.
And S110e, generating a third user interface, wherein the third user interface comprises a plurality of fourth parameter input areas and fifth parameter input areas associated with the fourth parameter input areas, each fourth parameter input area is used for a user to input encryption algorithm parameters, and each fifth parameter input area is used for the user to input security indexes.
In order to encrypt the corresponding field to be encrypted according to different encryption indexes, an encryption parameter mapping table can be set, wherein the encryption parameter mapping table comprises a plurality of encryption algorithm parameters and a security index corresponding to each encryption algorithm parameter. And generating a third user interface to facilitate the user to input a plurality of encryption algorithm parameters and the safety index on the third user interface.
S110f, acquiring a plurality of encryption algorithm parameters input by a user in the third user interface and a security index associated with each encryption algorithm parameter, and generating an encryption parameter mapping table according to the plurality of encryption algorithm parameters and the plurality of security indexes.
For example, the following encryption parameter mapping table is set:
encryption algorithm parameters: RSA algorithm parameter security index: 1
Encryption algorithm parameters: DSA algorithm parameter safety index: 2
Encryption algorithm parameters: ECC algorithm parameter safety index: 3
Encryption algorithm parameters: DES algorithm parameter security index: 4
S120, matching each initial field in the initial data table with a preset encrypted field to screen out fields to be encrypted and fields not to be encrypted, and storing sequence numbers of the fields to be encrypted and the fields not to be encrypted in the initial data table in segmentation information, wherein the fields to be encrypted are the same initial fields as the preset encrypted fields, and the fields not to be encrypted are the initial fields different from the preset encrypted fields.
For example, for the contact list, the preset encryption fields including "user name" and "mobile phone number" are set, the "user name" field and the "mobile phone number" field are fields to be encrypted, and the "user ID" and "mailbox" are fields not to be encrypted. The sequence number corresponding to each initial field of the contact list is respectively as follows:
field sequence number: 1 field: "user ID"
Field sequence number: 2 field: user name "
Field sequence number: 3, field: 'Mobile phone number'
Field sequence number: 4 field: mail box "

For example, for the above contact list, it includes only 4 initial fields, since the preset encryption field is set as "user name" and "mobile phone number", the number of the fields to be encrypted is 2, and if the preset range is set as 1 to 4, that is, the number of the fields to be encrypted is smaller than the total number of the initial fields included in the initial data table and is greater than one, at this time, each field to be encrypted is encrypted separately, and a first encryption field is generated.

S130a, judging whether the number of the fields to be encrypted is within a preset numerical range.
By judging the number of fields to be encrypted, different encryption schemes can be selected. For example, if the number of the fields to be encrypted is within a preset value range, each field to be encrypted can be encrypted separately to generate a plurality of first encrypted fields, and then the plurality of first encrypted fields are used as a whole to be encrypted to generate a second encrypted field; if the number of the fields to be encrypted is not within the preset value range, for example, if the number of the fields to be encrypted is the total number of the initial fields in the initial data table, the initial data table is taken as a whole to be encrypted, and if the number of the fields to be encrypted is one, only the fields to be encrypted are encrypted. In this embodiment, if the step S130a is executed to determine that the number of the fields to be encrypted is within the preset value range, the step S131 is executed, otherwise, the step S130b is executed.

For example, if the preset encryption fields include a "user name" field and a "mobile phone number" field, and the contact list includes a "user ID" field, a "user name" field, a "mobile phone number" field, and a "mailbox" field, the fields to be encrypted are the "user name" field and the "mobile phone number" field, the encryption index corresponding to the "user name" field is 1, and the encryption index corresponding to the "mobile phone number" field is 2, and according to the encryption parameter mapping table, the security index of the "RSA algorithm parameter" is 1, and the security index of the "DSA algorithm parameter" is 2, which correspond to the encryption indexes of the two fields to be encrypted.
S132, encrypting the field to be encrypted according to the target encryption algorithm parameter to generate a first encryption field.
For example, for the above contact list, the "user name" field is encrypted by the "RSA algorithm parameter" to generate the "user name" encrypted field; in addition, the 'mobile phone number' field is encrypted through the 'DSA algorithm parameter' to generate the 'mobile phone number' encrypted field.
S140, encrypting the plurality of first encryption fields as a whole to generate a second encryption field.
By re-encrypting a plurality of said first encrypted fields as a whole, the security of the encrypted fields can be further improved.
S150, combining the second encrypted field and the unencrypted field to generate a first encrypted data table.
By combining the second encrypted field and the unencrypted field, a first encrypted data table may be generated.

For example, if the determination result is yes, that is, all the initial fields in the initial data table are to-be-encrypted fields, the initial data table may be encrypted as a whole. In the embodiment of the present invention, if the determination result of executing the step S130b is yes, the step S160 is executed, otherwise, the step S130c is executed.
And S160, if the number of the fields to be encrypted is equal to the total number of the initial fields in the initial data table, encrypting the initial data table as a whole to generate a second encrypted data table.
For example, if the preset encryption fields include "user ID", "user name", "mobile phone number" and "mailbox", and the preset range is set to 0 to 3, especially for the contact list, 4 fields included therein are all matched with the preset encryption fields, that is, 4 fields are all the fields to be encrypted, and since the number of the fields to be encrypted is 4 and is not within the preset range, the initial data table may be an integral body, and the initial data table is encrypted.
S130c, judging whether the number of the fields to be encrypted is equal to one.
And executing a corresponding encryption method by judging whether the number of the fields to be encrypted is equal to one. For example, if the determination result is yes, that is, only one field to be encrypted exists in the initial data table, only the field to be encrypted may be encrypted. In the embodiment of the present invention, if the determination result of executing the step S130c is yes, the step S170 is executed.
S170, if the number of the fields to be encrypted is equal to one, encrypting the fields to be encrypted to generate a third encrypted field.
When the number of the fields to be encrypted is only one, only the fields to be encrypted are encrypted, and then step S180 is performed.
S180, combining the third encrypted field and the unencrypted field according to the segmentation information to generate a third encrypted data table.
