Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It is to be noted that, unless defined otherwise, 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. The terminology used herein is for the purpose of describing embodiments of the present application only and is not intended to be limiting of the application.

For the convenience of understanding, the technical terms and application scenarios related to the embodiments of the present application will be briefly described here:

HTTPS: the method is a transmission protocol for carrying out safe communication through a computer network, carries out communication through HTTP, establishes a full channel by utilizing SSL/TLS and encrypts a data packet. The primary purpose of HTTPS use is to provide authentication of the web server while protecting the privacy and integrity of the exchanged data. It is widely used for security sensitive communications on the world wide web, such as transaction payments.

Symmetric encryption algorithm: in the symmetric encryption algorithm, a data sender processes a plaintext (original data) and an encryption key together through a special encryption algorithm, and then the plaintext and the encryption key are changed into a complex encryption ciphertext to be sent out. After the receiver receives the ciphertext, if the receiver wants to decode the original text, the receiver needs to decrypt the ciphertext by using the key used for encryption and the inverse algorithm of the same algorithm so as to recover the ciphertext into readable plaintext. In the symmetric encryption algorithm, only one key is used, and both the sender and the receiver use the key to encrypt and decrypt data, so that the encryption key must be known by a secret party in advance.

Salt value: belonging to random values. When a user registers, the system combines the user password to generate a random number, which is called salt value, and is commonly called salting 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, and an HTTPS channel is established between the short message service end and the short message service provider. The short message service end is accessed to the enterprise application layer, and the short message service requirement is determined according to the instruction from the enterprise application layer. The short message service provider is a short message service provider platform of a third party and can provide an interface for calling the short message service for the short message service terminal. Here, the short message service may include, but is not limited to, a verification code short message, a notification short message, a service promotion short message, and the like.

Referring to fig. 1, the following describes an interaction process between a short message service side and a short message service provider by taking sending a verification code short message 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 app/webpage (belonging to an enterprise application layer);

2, the SMS terminal calls the interface of the SMS provider to generate the verification code

3, sending the verification code short message to a client of the user through a short message service provider;

4, the short message service end receives verification code information returned by the enterprise application layer;

5, the SMS server terminal calls the interface of the SMS provider to verify the verification code,

and 6, the short message service provider returns the verification result to the short message service end.

In the process, the short message service side and the short message service provider perform information interaction through the HTTPS channel, however, when verification code information is transmitted through the HTTPS channel, the verification code information is easily acquired by packet capturing, privacy of a client is further leaked, and security of private data of the client is damaged. Therefore, a short message transmission method capable of preventing the private data of the client from being easily acquired is required.

It should be understood that the short message service side and the short message service provider may be configured as independent physical servers, may also be configured as a server cluster or a distributed system formed by a plurality of physical servers, and may also be configured as a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, network service, cloud communication, middleware service, domain name service, security service, CDN, and a big data and artificial intelligence platform, but are not limited to the above forms.

Method embodiments provided herein 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 and device based on salt value encryption, electronic equipment and a computer readable storage medium, and aims to solve the problem that private data of a client is easily leaked in a short message transmission process between a short message service end and an external short message service provider, and improve the security of the private data of the client.

Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a short message transmission method based on salt value encryption according to an embodiment of the present application. As shown in fig. 2, the short message transmission method provided in the embodiment of the present 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 customer communication identification according to the customer communication identification corresponding to the short message to be sent.

The effective salt value information comprises an effective salt value and a salt value identification, the effective salt value and the salt value identification 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 a client at a client app/webpage, for example, a client user logs in an account on a client in a short message verification code mode, the client user initiates an instruction for requesting the verification code, and after receiving the instruction for requesting the verification code, the short message service end generates a short message to be sent corresponding to a client communication identifier of the client user.

Illustratively, the customer communication identifier may be a mobile phone number of the customer, an account number of the customer, and the like.

After the short message service end generates a short message to be sent, whether effective salt value information corresponding to a client communication identifier is stored locally or not is judged according to the client communication identifier corresponding to the current short message to be sent. It can be understood that the short message service side locally stores the salt value information corresponding to the plurality of client communication identifiers, each salt value information has an effective period, the salt value information is valid within the effective period, and if the effective period is exceeded, the salt value information is invalid.

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:

step S201, the short message service end sends a first salt value request to the salt value generation service end, and the first salt value request carries the client communication identifier.

Here, the salt value generation server is a server for generating a random salt value.

Step S202, after receiving the first salt request, the salt generation service end generates salt information corresponding to the client communication identifier according to the client communication identifier in the first salt request, and returns the salt information to the short message service end, wherein the salt information comprises a salt and a salt identifier, and the salt identifier have a unique corresponding relation.

Here, each time the salt value generation server generates a salt value, that is, 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 can be understood that, after the salt value generation server in step S202 generates salt value information corresponding to the client communication identifier according to the client communication identifier in the first salt value request, the method in this embodiment of the present application further includes:

step S301, the salt value generation 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 value corresponding to each salt value identifier.

Step S203, the short message service end stores the salt value information returned by the salt value generation service end locally, and determines the valid period of the salt value information according to the storage time, wherein the salt value information is valid salt value information within the valid period.

After receiving the salt value information returned by the salt value generation server, the short message service end stores the salt value information locally, and then determines the valid period of the salt value information according to the storage time. The length of the validity period is set in advance, for example, 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 side locally stores the effective salt value information corresponding to the client communication identifier may specifically include the following steps S111 to S112:

step S111, the short message service side judges whether the local salinity information corresponding to the client communication identification is stored, if so, step S112 is executed; if not, determining that the effective salt value information corresponding to the client communication identification is not stored locally.

Step S112, acquiring the valid period of the salt value information corresponding to the client communication identifier from the local, and if the valid period indicates that the salt value information is within the valid period, determining that the valid salt value information corresponding to the client communication identifier is stored locally; and if the valid period indicates that the salt value information exceeds the valid period, determining that valid salt value information corresponding to the client communication identifier is not stored locally.

It can be understood that the short message service end encrypts the current short message to be sent by using the effective salt value information corresponding to the client communication identifier.

Step S120, when the short message service end locally stores the effective salt value information corresponding to the client communication identifier, the short message service end encrypts the short message to be sent by using the effective salt value in the effective salt value information to obtain an encrypted short message.

The short message is encrypted based on a symmetric encryption algorithm and a salt value. For example, referring to fig. 5, encrypting the short message to be sent by using the effective salt value in the effective salt value information in step S120 to obtain an encrypted short message may specifically include the following steps S121 to S122:

step S121, obtaining a fixed key corresponding to the client communication identifier, and processing the fixed key according to the effective salt value in the effective salt value information to obtain a derivative key;

and S122, encrypting the short message to be sent according to a preset symmetric encryption algorithm and the derived key to obtain an encrypted short message.

It is understood 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 an expiration date to obtain a derivative key. And then encrypting the short message to be sent according to a preset symmetric encryption algorithm and the derived key to obtain an encrypted short message. Because the salt value has a valid period, after the valid period is exceeded, the salt value is invalid and can not be used, and only a new salt value can be requested from the salt value generation server again, so that derivative keys obtained at different times are different, and the key security of the encrypted short message is greatly improved.

Step S130, the short message service end sends the client communication identification, the encrypted short message and the salt value identification 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, the corresponding customer communication identifier and the salt identifier corresponding to the salt used in the encryption of the short message are sent to the short message service provider together.

Step S140, the short message service provider receives the encrypted short message and the salt value identification from the short message service end, obtains a salt value for decrypting the encrypted short message according to the salt value identification, and decrypts the encrypted short message according to the obtained salt value to obtain the decrypted short message content.

Referring to fig. 6, the obtaining of the salt value for decrypting the encrypted short message according to the salt value identifier in step S140 may specifically include the following steps S401 to S404:

step S401, the short message service provider judges whether a salt value corresponding to the salt value identification is stored locally.

When the sms service provider locally stores the salt value, the following step S402 is executed:

step S402, the short message service provider obtains the salt value from local.

When the short message service provider does not locally store the salt value, the following steps S403-S404 are executed:

step S403, the sms provider sends a second salt request to the salt generation service end, where the second salt request includes the salt identifier;

s404, after receiving the second salinity request, the salt generation service end searches for a salt corresponding to the salt identifier from the salt list according to the salt identifier in the second salinity request, and returns the found salt 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 by the salt value generation server, a unique salt value identifier is configured for the salt value, and then the salt value and the salt value identifier corresponding to the salt value are added 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, the decrypting the encrypted short message by the obtained salt value in step S140 to obtain the decrypted short message content includes the following steps S501 to S502:

step S501, acquiring a fixed key corresponding to the client communication identifier, and processing the fixed key according to the acquired salt value to obtain a derivative key;

step S502, the encrypted short message is decrypted according to a preset symmetric encryption algorithm and the derived key, and the decrypted short message content is obtained.

It can be understood that, in the embodiment of the present application, the short message is encrypted by using a symmetric encryption algorithm, so that the keys used in the encryption process and the decryption process are consistent.

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 valid period, so that the salt value is invalid and cannot be used for encryption once exceeding the valid period, the information encryption safety is improved, the difficulty of packet capturing of sensitive information of a client in the link transmission process is improved, and the decryption is difficult once the information is not decrypted in time due to the existence of a timing refreshing mechanism of the salt value. The security of the private data of the client is protected.

While certain embodiments of the present application have been described above, other embodiments are within the scope of the following claims. In some cases, the actions or steps recited in the claims may be performed in a different order than in the embodiments and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily have to be in the particular order shown or in sequential order to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

The embodiments in the present application are described in a progressive manner, and the same and similar parts among the embodiments can be referred to each other, and each embodiment focuses on the differences from the other embodiments. In particular, for the apparatus, device, and computer-readable storage medium embodiments, since they are substantially similar to the method embodiments, the description is relatively simple, and in relation to the description, reference may be made to some portions of the description of the method embodiments.

The apparatus, the device, the computer-readable storage medium, and the method provided in the embodiments of the present application correspond to each other, and therefore, the apparatus, the device, and the nonvolatile computer storage medium also have advantageous technical effects similar to those of the corresponding method.

In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry for implementing the logical method flows can be readily obtained by a mere need to program the method flows with some of the hardware description languages described above and into an integrated circuit.

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, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.

The systems, devices, modules or units illustrated in the above embodiments may be implemented by a computer chip or an entity, or by a product with certain functions. One typical implementation device is a computer. In particular, the computer may be, for example, a personal computer, a laptop computer, a cellular telephone, a camera phone, a smartphone, a personal digital assistant, a media player, a navigation device, an email device, a game console, a tablet computer, a wearable device, or a combination of any of these devices.

For convenience of description, the above devices are described as being divided into various units by function, and are described separately. Of course, the functions of the units can be implemented in the same software and/or hardware or in a plurality of software and/or hardware when implementing the embodiment of the present application.

As will be appreciated by one skilled in the art, embodiments of the present application may be provided as a method, system, or computer program product. Accordingly, embodiments of the present application may take the form of an entirely hardware embodiment, an entirely software embodiment or an embodiment combining software and hardware aspects. Furthermore, embodiments of the present application may take the form of a computer program product embodied on one or more computer-usable storage media (including, but not limited to, disk storage, CD-ROM, optical storage, and the like) having computer-usable program code embodied therein.

The present specification has been described with reference to flowchart illustrations and/or block diagrams of methods, apparatus (systems), and computer program products according to embodiments of the application. It will be understood that each flow and/or block of the flow diagrams and/or block diagrams, and combinations of flows and/or blocks in the flow diagrams and/or block diagrams, can be implemented by computer program instructions. These computer program instructions may be provided to a processor of a general purpose computer, special purpose computer, embedded processor, or other programmable data processing apparatus to produce a machine, such that the instructions, which execute via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be stored in a computer-readable memory that can direct a computer or other programmable data processing apparatus to function in a particular manner, such that the instructions stored in the computer-readable memory produce an article of manufacture including instruction means which implement the function specified in the flowchart flow or flows and/or block diagram block or blocks.

These computer program instructions may also be loaded onto a computer or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer or other programmable apparatus to produce a computer implemented process such that the instructions which execute on the computer or other programmable apparatus provide steps for implementing the functions specified in the flowchart flow or flows and/or block diagram block or blocks.

In a typical configuration, a computing device includes one or more processors (CPUs), input/output interfaces, network interfaces, and memory.

The memory may include forms of volatile memory in a computer readable medium, Random Access Memory (RAM) and/or non-volatile memory, such as Read Only Memory (ROM) or flash memory (flash RAM). Memory is an example of a computer-readable medium.

Computer-readable media, including both permanent and non-permanent, removable and non-removable media, may implement the information storage by any method or technology. The information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), Static Random Access Memory (SRAM), Dynamic Random Access Memory (DRAM), other types of Random Access Memory (RAM), Read Only Memory (ROM), Electrically Erasable Programmable Read Only Memory (EEPROM), flash memory or other memory technology, compact disc read only memory (CD-ROM), Digital Versatile Discs (DVD) or other optical storage, magnetic cassettes, magnetic tape disk storage or other magnetic storage devices, or any other non-transmission medium which can be used to store information that can be accessed by a computing device. As defined herein, a computer readable medium does not include a transitory computer readable medium such as a modulated data signal and a carrier wave.

It should also be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising an … …" does not exclude the presence of other like elements in a process, method, article, or apparatus that comprises the element.

In the embodiments of the present application, "at least one" means one or more, and "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, and means that there may be three relationships, for example, a and/or B, and may mean that a exists alone, a and B exist simultaneously, and B exists alone. Wherein A and B can be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" and similar expressions refer to any combination of these items, including any combination of singular or plural items. For example, at least one of a, b, and c may represent: a, b, c, a and b, a and c, b and c or a and b and c, wherein a, b and c can be single or multiple.

Embodiments of the 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. Embodiments of 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.
