Description
Technical Field
The present invention relates to the field of communications, and in particular, to a plaintext data transmitting method and apparatus, a storage medium, and an electronic apparatus.
Background
With the rapid development of networks, data on the networks become more and more, and how to ensure the data security, it becomes important to ensure that the data are not acquired by outsiders and are not randomly tampered.
For example, in the front-end application, the network communication with the service end is often very frequent, and the data content of the front-end and back-end communication can be intercepted through a developer panel of a browser or some package-grabbing tool, firstly, most content developers do not want to be identified by a third party, secondly, once the plaintext transmission data is intercepted, there is a possibility of being tampered, for example, the commodity price is 100 yuan, and if the plaintext transmission data is correctly identified, then the plaintext transmission data is tampered to 1 yuan, and the service end does not have a strict verification mechanism, which causes practical loss.
The existing solution is to adopt non-semantic naming for data fields of data, for example, price fields do not use price, but use abbreviations such as pp and the like for substitution, so that even if data is intercepted, the difficulty of data tampering is greatly improved because an interceptor cannot accurately identify the meaning of the fields. But theoretically, the complete identification data can still be obtained as long as the interceptor can know the meaning of the field abbreviation. And the maintenance cost to the front end and the back end is high, and the real meaning of each abbreviated field needs to be continuously contrasted and identified in the joint debugging process of developers at the front end and the back end, so that the workload is increased, and errors are easy to occur.

Accordingly, there is a need for improvement in the related art to overcome the disadvantages of the related art.

Fig. 2 is a flowchart (a) of a method for transmitting plaintext data according to an embodiment of the present invention, where the flowchart includes the following steps:
step S202, determining first plaintext data to be sent by a front end application;
step S204, encrypting the first plaintext data according to a pre-acquired back-end public key of a back-end application to obtain encrypted first plaintext data;
step S206, sending the encrypted first plaintext data to the back-end application to instruct the back-end application to analyze the encrypted first plaintext data according to a back-end private key of the back-end application, so as to obtain the first plaintext data.
Through the steps, when the front-end application sends the plaintext data to the back-end application, the plaintext data is encrypted through the public key of the back-end application, and then the back-end application decrypts the encrypted plaintext data through the private key of the back-end application, so that the data security of the data sent by the front-end application to the back-end application is ensured, the problem that communication data are easily acquired by a third party in the communication process of the front-end application and the back-end application is solved, and the risk that the data are hijacked, identified and tampered is further avoided.
It should be noted that, before data encryption is performed, a public key and a private key corresponding to a front-end application and a back-end application must be generated, specifically, a back-end public key and a back-end private key of the back-end application, a front-end public key of the front-end application and a front-end private key of the front-end application are generated through an asymmetric encryption algorithm; the method comprises the steps of sending a front-end public key to a back-end application, and receiving the back-end public key sent by the back-end application.
It should be noted that, in the asymmetric encryption algorithm, each communication party needs two keys, namely, a public key and a private key, which can be encrypted and decrypted with each other, wherein the public key is used for encrypting data, the private key is used for decrypting data, that is, the public key is public and can be disclosed to any person and object, and the private key is owned by the person and cannot be disclosed to the outside.
Specifically, in the communication process between the front-end application and the back-end application, the front-end application needs to send the front-end public key to the back-end application, the back-end application needs to send the back-end public key to the front-end application, the front-end application stores the front-end private key by itself, and the back-end application stores the back-end private key by itself.
Further, the step S204 may be specifically divided into the following steps:
the method comprises the following steps: converting the first plaintext data into a first string;
step two: and encrypting the first character string through the rear-end public key to obtain encrypted first plaintext data.
That is, before the front-end application communicates with the back-end application, the first plaintext data needs to be converted into a first character string, and the first character string is encrypted by the public key of the back-end application and then transmitted. For example, the front-end application needs to report a user gender information { gender: the ' male ' is applied to the back end, and the gender information is converted into a first character string ' { \\ generator \ firstly: \\ male \ is carried out, then a first character string is encrypted by using a rear-end public key, and the content format of the encrypted first plaintext data transmitted finally is { value: xxxxx }.
In an alternative embodiment, fig. 3 is a flowchart (ii) of a plaintext data sending method according to an embodiment of the present invention, that is, before or after determining that the front end applies the first plaintext data to be sent, the method further includes the following steps:
step S302: receiving encrypted second plaintext data sent by the backend application, wherein the encrypted second plaintext data is determined by the following method: the back-end application encrypts second plaintext data according to a front-end public key of the front-end application;
step S304: and analyzing the encrypted second plaintext data according to a front-end private key applied by the front end to obtain the second plaintext data.
Through the steps, the front-end application receives the second plaintext data which is sent by the back-end application and encrypted by using the front-end public key, and then the front-end application decrypts the second plaintext data by using the front-end private key to obtain the second plaintext data, so that the data security sent by the back-end application to the front-end application is ensured, the problem that the second plaintext data sent by the back-end application is easily acquired by a third party in the communication process of the front-end application and the back-end application is solved, and the risk that the second plaintext data is hijacked, identified and tampered is avoided.
Further, analyzing the encrypted second plaintext data according to a front-end private key applied by the front end to obtain the second plaintext data, including: analyzing the encrypted second plaintext data according to the front-end private key to obtain a second character string, wherein the second character string is obtained by converting the second plaintext data by the back-end application; and converting the second character string to obtain the second plaintext data.
That is to say, before the back-end application encrypts the second plaintext data, the back-end application also performs character conversion on the second plaintext data to obtain a second character string, and then encrypts the second character string, and after the front-end application receives the encrypted second plaintext data, the front-end application decrypts the second character string to obtain the second character string, and then the second plaintext data can be obtained through the second character string.
It should be noted that, determining the first plaintext data to be sent by the front-end application is implemented in the following manner: establishing network communication transmission channels of the front-end application and the back-end application; receiving a data request of the back-end application through the network communication transmission channel; and responding to the data request, and determining first plaintext data corresponding to the data request to be sent by the front-end application.
That is, the front-end application receives a data request of the back-end application through the network communication transmission channel, and determines the first plaintext data to be sent to the back-end application according to the data request.
It is to be understood that the above-described embodiments are only a few, but not all, embodiments of the present invention. In order to better understand the sending method of the plaintext data, the following describes the above process with reference to an embodiment, but the invention is not limited to the technical solution of the embodiment of the present invention, and specifically:
in an alternative embodiment, fig. 4 is a schematic diagram of a sending method of plaintext data according to an embodiment of the present invention, specifically:
by using an asymmetric encryption algorithm, the front-end and the back-end (corresponding to the front-end application and the back-end application in the above embodiments) respectively generate their own public key and private key, where the public key is used to encrypt data and the private key is used to decrypt data, and then the front-end and the back-end exchange their respective public keys, that is, the front-end application sends the front-end public key to the back-end application, and the back-end application sends the back-end public key to the front-end application.
Before the front-end and back-end communication, data (corresponding to plaintext data in the above-described embodiment) is converted into a character string, encrypted by a public key of a transmission target, and then transmitted. For example, the front-end application needs to report a user gender information { gender: "male", firstly converting the user gender information into a character string "{ \\" generator \ ": \\ male \ is then encrypted with a backend public key, and the final transmitted content format is { value: xxxxx }.
The back-end application receives the data and then decrypts the data through a back-end private key to obtain a character string, and then converts the character string into an object for use, and according to the example, the character string is decrypted to obtain "{ \\" generator \ ": \\ male \ is converted into an object of { gender: "male".
In order to facilitate development, the network communication method is uniformly packaged, data is encrypted before a request, and is decrypted after a response is obtained, so that the process of encrypting and decrypting the data is insensitive to developers, and the development efficiency is improved.
It should be noted that, the front-end application generates its own public key and private key, the public key is used for encrypting data, and only the private key can decrypt data; the back-end application generates a public key and a private key of the back-end application, wherein the public key is used for encrypting data, and only the private key can be used for decrypting; the front-end application uses the back-end public key for data encryption, the encrypted data is transmitted to the back-end application through a network, and the back-end application uses the back-end private key to decrypt the data.
In addition, according to the technical scheme of the embodiment, the data of the front-end and back-end network communication is encrypted, that is, all the data transmitted by the network are encrypted data, so that the possibility of hijacking identification and tampering does not exist, the tampering cannot be deciphered even if the data are hijacked, and the data security is ensured. And the front end and the back end are uniformly encrypted before data is sent and decrypted after data is received, so that the development efficiency is improved, and developers can feel the data processing process noninductively.
Through the above description of the embodiments, those skilled in the art can clearly understand that the method according to the above embodiments can be implemented by software plus a necessary general hardware platform, and certainly can also be implemented by hardware, but the former is a better implementation mode in many cases. Based on such understanding, the technical solutions of the present invention may be embodied in the form of a software product, which is stored in a storage medium (such as ROM/RAM, magnetic disk, optical disk) and includes instructions for enabling a terminal device (such as a mobile phone, a computer, a server, or a network device) to execute the method according to the embodiments of the present invention.
In this embodiment, a plaintext data sending apparatus is further provided, and the apparatus is used to implement the foregoing embodiments and preferred embodiments, and the description already made is omitted. As used below, the term "module" may be a combination of software and/or hardware that implements a predetermined function.
