Detailed Description
The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.
It is to be noted that all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs unless defined otherwise. The terminology used herein is for the purpose of describing embodiments of the application only and is not intended to be limiting of the application.
In order to facilitate understanding of the present application, technical terms and application scenarios related to embodiments of the present application are briefly described herein:
HTTPS: is a transmission protocol for secure communication over a computer network, communicating via HTTP, establishing a full channel using SSL/TLS, encrypting data packets. The main purpose of HTTPS use is to provide authentication of web servers while protecting the privacy and integrity of the exchanged data. It is widely used in security-sensitive communications on the world wide web, such as transaction payments.
Symmetric encryption algorithm: in the symmetric encryption algorithm, a data sender processes plaintext (original data) and an encryption key together through a special encryption algorithm, and then the plaintext (original data) and the encryption key are changed into complex encrypted ciphertext to be sent out. After receiving the ciphertext, the receiver needs to decrypt the ciphertext by using the encryption key and the inverse algorithm of the same algorithm to restore the ciphertext into readable plaintext if the receiver wants to interpret the ciphertext. In the symmetric encryption algorithm, only one key is used, and both the sender and the receiver encrypt and decrypt data by using the key, which requires that the decryption party must know the encryption key in advance.
Salt value: belonging to a random value. At user registration, the system is used to combine the random value generated by the user password, known as salt value, and known as salt value.
The embodiment of the application provides a short message transmission method based on salt value encryption, which is applied to a short message transmission system, wherein the short message transmission system comprises a short message service end, a short message service provider and a client, wherein an HTTPS channel is established between the short message service end and the short message service provider. The short message service access is connected to the enterprise application layer, and the short message service requirement is determined according to the instruction from the enterprise application layer. The SMS provider is a platform of the third-party SMS provider and can provide an interface for calling the SMS for the SMS terminal. The short message service may include, but is not limited to, verification code short message, notification short message, service promotion short message, etc.
Referring to fig. 1, the following describes an interaction process between a short message service end and a short message service provider by taking sending a short message with verification code as an example, and the specific process is as follows:
1, a short message service end receives a verification code request initiated by a user on a client end app/webpage (belonging to an enterprise application layer);
2, the SMS server calls the interface of SMS service provider to generate verification code
3, Sending the verification code short message to the client side of the user through the short message service provider;
4, the short message server receives verification code information returned by the enterprise application layer;
5, the SMS server calls the interface of the SMS service provider to verify the verification code,
And 6, returning the verification result to the short message service end by the short message service provider.
In the above process, the short message service end and the short message service provider interact information through the HTTPS channel, however, the verification code information is easily acquired by capturing the packet when transmitted by using the HTTPS channel, thus causing the privacy of the client to be revealed and jeopardizing the security of the private data of the client. Therefore, a short message transmission method capable of preventing client privacy data from being easily acquired is required.
It should be understood that the short message service end and the short message service provider may be configured as independent physical servers, may be configured as a server cluster or a distributed system formed by a plurality of physical servers, and may be configured as a cloud server for providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, and basic cloud computing services such as big data and artificial intelligence platforms, but are not limited to the above forms.
The method embodiments provided by the present application may be described in the general context of computer-executable instructions, such as program modules, being executed by a computer. Generally, program modules include routines, programs, objects, components, data structures, etc. that perform particular tasks or implement particular abstract data types. The application may also be practiced in distributed computing environments where tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules may be located in both local and remote computer storage media including memory storage devices.
The embodiment of the application mainly aims to provide a short message transmission method, a device, electronic equipment and a computer readable storage medium based on salt value encryption, aiming at solving the problem that customer privacy data is easy to leak in the short message transmission process of a short message service end and an external short message service provider and improving the safety of the customer privacy data.
Referring to fig. 2, fig. 2 shows a flow chart of a method for transmitting a short message based on salt encryption according to an embodiment of the present application. As shown in fig. 2, the short message transmission method provided by the embodiment of the application includes, but is not limited to, the following steps:
step S110, the short message service end judges whether the short message service end locally stores effective salt value information corresponding to the client communication identification according to the client communication identification corresponding to the short message to be sent.
The effective salt value information comprises an effective salt value and a salt value identifier, wherein the effective salt value and the salt value identifier have a unique corresponding relation, and the effective salt value is effective within a preset effective period.
It can be understood that the short message service end determines the short message service requirement according to the instruction of the enterprise application layer and generates the short message to be sent. The instruction of the enterprise application layer is initiated by the client at the client app/webpage, for example, the client performs a login account operation on the client, needs to login in a short message verification code mode, initiates an instruction of requesting the verification code on the client, and generates a short message to be sent corresponding to the client communication identifier of the client after receiving the instruction of requesting the verification code.
The customer communication identifier may be a mobile phone number of the customer, an account number of the customer, or the like.
After the short message server generates the short message to be sent, judging whether the effective salt value information corresponding to the client communication identification is stored locally according to the client communication identification corresponding to the current short message to be sent. It can be understood that the short message service end locally stores salt value information corresponding to a plurality of client communication identifiers, each salt value information has an effective period, the effective salt value information is used in the effective period, and the effective period is not used.
Referring to fig. 3, when the short message service end does not locally store the effective salt value information corresponding to the client communication identifier, the embodiment of the present application further includes the following steps S201 to S203:
in step S201, the short message service end sends a first salt request to the salt generating service end, where the first salt request carries the client communication identifier.
Here, the salt value generation server is a server for generating random salt values.
Step S202, after the salt value generation server receives the first salt value request, salt value information corresponding to the client communication identifier is generated according to the client communication identifier in the first salt value request, the salt value information is returned to the short message server, the salt value information comprises a salt value and a salt value identifier, and the salt value identifier have a unique corresponding relationship.
Here, each time the salt value generation server generates a salt value, a unique salt value identifier is configured for the salt value, and the salt value identifier is used for marking the currently generated identifier.
It may be appreciated that, after the salt generating server in step S202 generates salt information corresponding to the client communication identifier according to the client communication identifier in the first salt request, the method in the embodiment of the present application further includes:
step S301, the salt value generating server adds the salt value and the salt value identifier in the salt value information to a preset salt value list, where the salt value list is used to record the salt values corresponding to the salt value identifiers.
In step S203, the short message service side stores the salt information returned by the salt generating service side locally, and determines the effective period of the salt information according to the storage time, where the salt information is effective salt information within the effective period.
After receiving the salt information returned by the salt generation server, the short message server stores the salt information locally, and then determines the effective period of the salt information according to the storage time. The duration of the expiration date is preset, for example, set to 2 minutes, 5 minutes, or the like. The expiration date corresponding to each salt value may be recorded by a local list.
Referring to fig. 4, the step S110 of determining whether the short message service end locally stores valid salt value information corresponding to the client communication identifier may specifically include the following steps S111-S112:
Step S111, the sms server determines whether the salt information corresponding to the client communication identifier is locally stored, and if yes, step S112 is executed; and if not, determining that the effective salt value information corresponding to the client communication identification is not stored locally.
Step S112, obtaining the effective period of the salt information corresponding to the client communication identifier from the local, and if the effective period indicates that the salt information is within the effective period, determining that the effective salt information corresponding to the client communication identifier is stored locally; and if the effective period indicates that the salt information exceeds the effective period, determining that the effective salt information corresponding to the client communication identifier is not stored locally.
It can be understood that the short message service end encrypts the short message to be sent by using the effective salt value information corresponding to the client communication identifier.
And step S120, when the short message service end locally stores effective salt value information corresponding to the client communication identifier, the short message service end encrypts the short message to be sent by utilizing the effective salt value in the effective salt value information to obtain an encrypted short message.
The embodiment of the application encrypts the short message based on the symmetric encryption algorithm and the salt value. As an example, referring to fig. 5, in step S120, the encrypting the short message to be sent by using the effective salt value in the effective salt value information to obtain an encrypted short message may specifically include the following steps S121-S122:
step S121, a fixed key corresponding to the client communication identifier is obtained, and the fixed key is processed according to the effective salt value in the effective salt value information to obtain a derivative key;
and step S122, encrypting the short message to be sent according to a preset symmetric encryption algorithm and the derivative key to obtain an encrypted short message.
It will be appreciated that in the embodiment of the present application, each client communication identifier has a corresponding fixed key, and then the fixed key is processed by a salt value with a validity period to obtain a derivative key. And then encrypting the short message to be sent according to a preset symmetric encryption algorithm and the derivative key to obtain an encrypted short message. Because the salt value is valid, the salt value can not be reused after the valid period is exceeded, and a new salt value can only be requested to the salt value generation server again, so that the derived keys obtained at different times are different, and the key security of the encrypted short message is greatly improved.
And step S130, the short message service end sends the customer communication identifier, the encrypted short message and the salt value identifier in the effective salt value information to a short message service provider.
It can be understood that after the short message service end completes the encryption of the short message, the encrypted short message is sent to the short message service provider together with the corresponding client communication identifier and the salt value identifier corresponding to the salt value used in the process of encrypting the short message.
And step S140, the short message service provider receives the encrypted short message and the salt value identification from the short message service end, acquires a salt value for decrypting the encrypted short message according to the salt value identification, and decrypts the encrypted short message through the acquired salt value to obtain the decrypted short message content.
Referring to fig. 6, the step S140 of obtaining the salt value for decrypting the encrypted sms according to the salt value identifier may specifically include the following steps S401 to S404:
in step S401, the sms service provider determines whether a salt corresponding to the salt identifier is locally stored.
When the short message service provider locally stores the salt value, the following step S402 is executed:
in step S402, the sms service provider obtains the salt value locally.
When the short message service provider does not store the salt value locally, the following steps S403 to S404 are executed:
step S403, the short message service provider sends a second salt request to the salt generating server, where the second salt request includes the salt identifier;
s404, after receiving the second salt request, the salt generating server searches a salt value corresponding to the salt value identifier from the salt value list according to the salt value identifier in the second salt request, and returns the searched salt value to the short message service provider.
It can be understood that the salt value generation server is locally provided with a salt value list, and each time a salt value is generated, the salt value generation server configures a unique salt value identifier for the salt value, and then adds the salt value and the salt value identifier corresponding to the salt value list, so that the salt value corresponding to each salt value identifier can be found through the salt value list.
Referring to fig. 7, in step S140, the decrypting the encrypted short message through the obtained salt value to obtain the decrypted short message content includes the following steps S501-S502:
step S501, obtaining a fixed key corresponding to the client communication identifier, and processing the fixed key according to the obtained salt value to obtain a derivative key;
And step S502, decrypting the encrypted short message according to a preset symmetric encryption algorithm and the derivative key to obtain decrypted short message content.
It can be appreciated that the embodiment of the application adopts a symmetric encryption algorithm to encrypt the short message, so that the encryption process and the decryption process use the same secret key.
According to the scheme of the embodiment of the application, the short message server encrypts the short message to be sent by using the effective salt value, and the salt value has the effective period, so that the salt value can be invalid and can not be used for encryption once exceeding the effective period, thereby increasing the security of information encryption, improving the difficulty of capturing packets of sensitive information of a client in the link transmission process, and being difficult to decrypt once the information is decrypted in time due to the existence of a timing refreshing mechanism of the salt value. The security of the private data of the clients is protected.
The short message transmission method according to the embodiment of the application is described in detail below by a specific example.
Step S601, the SMS server judges whether the SMS server locally stores effective salt value information corresponding to the client communication identification according to the client communication identification corresponding to the SMS to be sent, if yes, step S606 is executed; if not, executing the steps S602-S605; the effective salt value information comprises an effective salt value and a salt value identifier, wherein the effective salt value and the salt value identifier have a unique corresponding relation, and the effective salt value is effective within a preset effective period.
In step S602, the short message service end sends a first salt request to the salt generating service end, where the first salt request carries the client communication identifier.
Step S603, after the salt value generating server receives the first salt value request, according to a client communication identifier in the first salt value request, salt value information corresponding to the client communication identifier is generated, the salt value information is returned to the short message server, where the salt value information includes a salt value and a salt value identifier, and the salt value identifier have a unique corresponding relationship.

The foregoing describes certain embodiments of the application, other embodiments being within the scope of the following claims. In some cases, the actions or steps recited in the claims can be performed in a different order than in the embodiments and still achieve desirable results. Furthermore, the processes depicted in the accompanying drawings do not necessarily have to be in the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing are also possible or may be advantageous.
The embodiments of the present application are described in a progressive manner, and the same and similar parts of the embodiments are all referred to each other, and each embodiment is mainly described in the differences from the other embodiments. In particular, for apparatus, devices, computer readable storage medium embodiments, the description is relatively simple as it is substantially similar to method embodiments, with reference to the section of the method embodiments being relevant.
The apparatus, the device, the computer readable storage medium and the method provided by the embodiments of the present application correspond to each other, and therefore, the apparatus, the device, the non-volatile computer storage medium also have similar beneficial technical effects as those of the corresponding method, and since the beneficial technical effects of the method have been described in detail above, the beneficial technical effects of the corresponding apparatus, device, and computer storage medium are not described here again.
In the 90s of the 20 th century, improvements to one technology could clearly be distinguished as improvements in hardware (e.g., improvements to circuit structures such as diodes, transistors, switches, etc.) or software (improvements to the process flow). However, with the development of technology, many improvements of the current method flows can be regarded as direct improvements of hardware circuit structures. Designers almost always obtain corresponding hardware circuit structures by programming improved method flows into hardware circuits. Therefore, an improvement of a method flow cannot be said to be realized by a hardware entity module. For example, a programmable logic device (Programmable Logic Device, PLD) (e.g., field programmable gate array (Field Programmable GATE ARRAY, FPGA)) is an integrated circuit whose logic functions are determined by user programming of the device. A designer programs to "integrate" a digital system onto a PLD without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Moreover, nowadays, instead of manually manufacturing integrated circuit chips, such programming is mostly implemented with "logic compiler (logic compiler)" software, which is similar to the software compiler used in program development and writing, and the original code before being compiled is also written in a specific programming language, which is called hardware description language (Hardware Description Language, HDL), but HDL is not just one, but a plurality of kinds, such as ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language), and VHDL (Very-High-SPEED INTEGRATED Circuit Hardware Description Language) and Verilog are currently most commonly used. It will also be apparent to those skilled in the art that a hardware circuit implementing the logic method flow can be readily obtained by merely slightly programming the method flow into an integrated circuit using several of the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer readable medium storing computer readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, application SPECIFIC INTEGRATED Circuits (ASICs), programmable logic controllers, and embedded microcontrollers, examples of controllers include, but are not limited to, the following microcontrollers: ARC625D, atmel AT91SAM, microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic of the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller in a pure computer readable program code, it is well possible to implement the same functionality by logically programming the method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers, etc. Such a controller may thus be regarded as a kind of hardware component, and means for performing various functions included therein may also be regarded as structures within the hardware component. Or even means for achieving the various functions may be regarded as either software modules implementing the methods or structures within hardware components.
