DETAILED DESCRIPTION

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0016] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0017] In the related technology, various algorithms can be used to ensure that data during the communication process is secure, complete, and cannot be intercepted.

[0018] One technology is to encrypt text messages during transmission by using font tools (fontTools can provide a series of tools to process font files). Dynamic mapping is performed on text messages; the encryption method for graphic messages is to encrypt the image in the time domain by using scrambling encryption and grayscale encryption, and then encrypt the image in the frequency domain by using frequency domain encryption. After encryption is completed, the encrypted message is again generated with fontTools to generate a dynamic verification script.

[0019] There is another technology that authenticates user information based on 5G messages when sending messages, which can ensure the accuracy of user information and improve the security of subsequent data transmission; when the user information authentication is successful, the security of online message data transmission can be improved by differentially encoding and encrypting the online message data.

[0020] The 5G messages in current personal mobile terminals store a lot of personal sensitive information, such as salary messages, transfer messages, balance reminder messages, account password messages, etc. This type of information is stored and displayed in plain text in the mobile terminal. Anyone who gets the unlocked terminal can see the sensitive privacy information inside.

[0021] In the related art, the privacy of sensitive information in 5G messages received by user terminals is poor.

[0022] The message display method provided by the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0023] Figure 1 A message display method provided by an exemplary embodiment of the present application is shown, which is applied to a user terminal. The method 100 can be executed by an electronic device, which can be a mobile phone, a computer, etc. Figure 1 As shown, the method mainly includes the following steps: S101: receiving a message body carrying an encryption identifier sent by a message platform.

[0024] The message body includes a desensitized message corresponding to the original text message and an encrypted message corresponding to the original text message.

[0025] In the embodiment of the present application, the user terminal receives a message body carrying an encryption identifier sent by the message platform. The encryption identifier can be <privatemsg>true< / privateMsg> The identification field can also be other identifications, which are used to identify that the message body is encrypted and distinguish it from the unencrypted message received by the user terminal. If there is no encryption identification, the user terminal can directly display the received message, which helps to improve the efficiency of message transmission. The user terminal can be a 5G message terminal or other types of message terminals, which is not specifically limited in the embodiments of the present application. The message body may include a desensitized message corresponding to the original text message and an encrypted message corresponding to the original text message. The original text message that needs to be encrypted is generally some private information with sensitive content. It is usually transmitted after desensitization processing to reduce the possibility of privacy information leakage.

[0026] In an optional implementation, before receiving the message body carrying the encryption identifier sent by the message platform, the method may further include the following steps: Step 1: Receive the instruction to set up privacy message encryption and the second privacy password; the user terminal can set up a privacy message password page, on which a privacy message encryption switch and an input box for the second privacy password are set. The user can set it by voice or enter it manually.

[0027] Step 2: Generate a message encryption key pair, wherein the message encryption key pair includes an asymmetric public key and a private key; Step 3: Encrypt the private key using the second privacy password, and obtain and save the encrypted private key; Step 4: Send the public key and the user ID corresponding to the user terminal to the message platform. The user ID corresponding to the user terminal can be a user number or user account information, which is not specifically limited in the present embodiment.

[0028] Through the above implementation, the user can pre-set the encryption of private messages and obtain a message encryption key pair. The user terminal can ensure the security of the private key by encrypting and storing the private key of the generated encryption key pair, thereby avoiding the security of subsequent received messages.

[0029] In an optional implementation, performing the above step 2, generating a message encryption key pair includes: The elliptic curve algorithm is used to establish the token coefficient library; The message encryption key pair is generated according to the token coefficient library and the randomly generated character string.

[0030] In an embodiment of the present application, an elliptic curve algorithm may be used to establish a token coefficient library, or other algorithms may be used to establish it; then, a message encryption key pair (asymmetric public key and private key) is generated based on the created token coefficient library and a randomly generated string.

[0031] In the above optional implementation, the use of an elliptic curve algorithm to establish a token coefficient library includes: (1) Obtaining a first additive cluster and a second additive cluster on an elliptic curve, wherein the generators of the first additive cluster and the second additive cluster are the same, and the order of the first additive cluster is greater than or equal to 2 1 The user terminal can select the first additive cluster W1 and the second additive cluster W2 on the elliptic curve, the generator of the W1 cluster is p, the order is q greater than or equal to 2l, where l is the security factor, and the generator of the W2 cluster is p.

[0032] (2) Construct a bilinear map and a hash function based on the first addition cluster and the second addition cluster; the user terminal can construct a bilinear map e: W1*W2→W2, a hash function F1: {0,1}*→W1*, F2: {0,1}*→Zq*, F3: W2→Zq*, F4: W1→Zq* based on W1 and W2.

[0033] (3) Generate the master key and the corresponding master public key according to the hash function; in this embodiment of the application, the master key X can be selected in Zq* Zq*, and calculate the corresponding master public key Y=xP.

[0034] (4) Constructing the token coefficient library according to the first addition cluster and the second addition cluster, the bilinear map, the hash function, and the master public key. The token coefficient library constructed by the user terminal is {W1, W2, q, p, e, F1, F2, F3, F4, Y}.

[0035] In the embodiment of the present application, a message encryption key pair can be generated based on the token coefficient library and the randomly generated string. For example, an asymmetric public key and private key can be generated based on the randomly generated string storeKey, where the public key is T 公 =F1 (storeKey), whose private key is T 私 =xF1(storeKey).

[0036] In an optional implementation, encrypting the private key using the second privacy password to obtain and save the encrypted private key includes: The encryption private key K is obtained by the following formula using the SM4 algorithm: K=SM4(F(T 私 , SaltStr), KeySM4), Among them, SaltStr is a string of fixed length, F(T 私 , SaltStr) is the content encrypted by SM4, F function is the string cross-merge function, KeySM4 is the second privacy password, T 私 Represents the private key.

[0037] In an embodiment of the present application, the SM4 algorithm can be used to obtain the encrypted private key K. The SM4 algorithm is a symmetric encryption block cipher algorithm. Take the rule of string cross-merging as an example: string one is: abcd, string two is: 123456, then the result of merging string one and string two is: a1b2c3d456. In an embodiment of the present application, a string cross-merge function can be used to perform preliminary processing on the private key, and then the SM4 symmetric encryption algorithm is used to encrypt the merged private key according to the second privacy password to obtain the final encrypted private key K. The use of the SM4 algorithm can improve the security of the private key. In an embodiment of the present application, other methods can also be used to obtain the encrypted private key K, without specific limitation.

[0038] S102: Displaying the desensitized message on a message page.

[0039] In the embodiments of the present application, Figure 2 As shown, the user terminal can display the received desensitized message on the message page.

[0040] S103: In response to an operation request to view the original text message corresponding to the desensitized message, an input first privacy password is obtained.

[0041] In an embodiment of the present application, the user terminal can obtain the input first privacy password in response to the operation request of viewing the original text message corresponding to the desensitized message. The first privacy password can be used to decrypt the encrypted message in the message body.

[0042] In an optional implementation, a view original text button is spliced ​​into the message body; and in response to an operation request to view the original text message corresponding to the desensitized message, obtaining the input first privacy password includes: In response to an operation request for the view original text button displayed on the message page, displaying an input box for a first privacy password; The first privacy password entered in the input box is obtained.

[0043] In an embodiment of the present application, the message body received by the user terminal may include a view original text button, and the user terminal may directly call the view original text button to display it on the message page. The user terminal may respond to an operation request for the view original text button displayed on the message page by displaying an input box for the first privacy password; and then obtain the first privacy password entered in the input box.

[0044] S104: When the first privacy password is consistent with the pre-acquired second privacy password, the original text message is obtained, and the original text message is displayed on the message page.

[0045] In an embodiment of the present application, when the first privacy password is consistent with the pre-acquired second privacy password, the user terminal can use the first privacy password to decrypt the encrypted private key, and then decrypt the encrypted message using the private key obtained by decryption, obtain the original text message and display it on the message page.

[0046] It should be noted that if the first privacy password obtained by the user terminal is inconsistent with the second privacy password used when encrypting the private key, then the correct private key cannot be obtained, that is, it cannot be decrypted correctly. When encrypting and transmitting private messages, the embodiment of the present application can use a secondary authentication method to protect the private display of messages, which helps to improve the security of private messages and avoid leaking users' private messages.

[0047] If the first privacy password obtained by the user terminal is inconsistent with the pre-acquired second privacy password, the user terminal may give a prompt on the message page, and the user may then re-enter the first privacy password; the user terminal may also use the first privacy password to decrypt the encrypted message, display the incorrect original text message, and mark "decryption error", which is not specifically limited in the embodiments of the present application.

[0048] In practical applications, the first privacy password can be used to decrypt the pre-stored encrypted private key K using the SM4 algorithm, and the reverse rule of string cross-merging can be used to remove SaltStr and decompose the private key T 私 In a specific implementation, the user terminal can use the private key to reversely decrypt the originalMsg.data value in the view original text button of the message body to obtain the original text message and display it on the message page.

[0049] In an optional implementation, after displaying the original text message, the method further includes: In response to receiving an instruction to close the message page, the message page is closed and the original text message is deleted.

[0050] In an embodiment of the present application, after the user terminal displays the original text message, it can respond to receiving an instruction to close the message page, close the message page, and delete the original text message, thereby reducing the possibility of privacy information leakage, reducing the memory occupied by the information, and saving resources.

[0051] In an embodiment of the present application, a user terminal can receive a message body carrying an encryption identifier sent by a message platform, wherein the message body includes a desensitized message corresponding to the original text message and an encrypted message corresponding to the original text message; display the desensitized message on a message page; in response to an operation request to view the original text message corresponding to the desensitized message, obtain the input first privacy password; when the first privacy password is consistent with the pre-acquired second privacy password, obtain the original text message, and display the original text message on the message page. This not only effectively protects the privacy of personal messages, but also makes data display more secure, reliable and efficient, and can also enrich application scenarios and greatly improve user experience.

The recommended action click message behavior postback.data="set_by_decrypt_origin_msg" is reported to the message platform.

[0067] In an optional implementation, after the message body is sent to the user terminal corresponding to the receiving user identifier, a return message can be sent to the business platform. The return message carries information that the message body has been successfully sent. For example, after the message body is successfully sent, the message platform can call back to the business platform, and the message is sent successfully and carries the encrypted parameter information of the message.

[0068] In an embodiment of the present application, the message platform can receive a receiving user identifier, an original text message, and a desensitized message transmitted by a business platform; when it is determined based on the receiving user identifier that the user corresponding to the receiving user identifier has set up privacy message encryption, the original text message is encrypted using a pre-stored public key corresponding to the receiving user identifier to obtain an encrypted message; a message body is assembled based on the encrypted message and the desensitized message, and the message body is sent to a user terminal corresponding to the receiving user identifier, which can improve data security and reliability and protect privacy data.
