The embodiment of the invention relates to the technical field of data processing, in particular to a data transmission method, a data transmission device, data transmission equipment and a storage medium.
Background
With the rapid development of internet technology, business systems such as merchant systems are developed more and more according to business requirements of a large number of third-party organizations. At this time, when the business system communicates with each third-party mechanism, a communication mechanism corresponding to the asynchronous callback exists, for example, in a payment scenario of the business system, the third-party mechanism sends a corresponding account receipt notification to the business system when payment is successful.
Considering that the service system and the third-party organization usually adopt a public network for communication, the service system provides a network port accessible by the public network to the third-party organization, so that the third-party organization sends a corresponding asynchronous callback notification to the network port. At this time, the attacker may also send the forged asynchronous callback notification to the service system through a network port accessible to the public network, and the service system cannot identify the authenticity of the received asynchronous callback notification.
At present, data transmission is generally performed between a service system and a third-party organization by adopting a digital signature or transmission link binding mode, so as to prevent a false notification attack initiated by an attacker. However, both the service system and the third-party organization need to maintain a reliable key management system for digital signatures, and the binding of transmission links also needs to be maintained in real time, so that the complexity of system layout for anti-counterfeiting attacks by both communication parties is greatly increased, and the keys of the digital signatures are easily leaked or violently broken, thereby reducing the security of data transmission.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures. In addition, the embodiments and features of the embodiments in the present invention may be combined with each other without conflict.
Example one
Fig. 1A is a flowchart of a data transmission method according to an embodiment of the present invention, which is applicable to a scenario in which a third-party attacker is prevented from attacking a service system by forging information when asynchronous callback data transmission is performed between any service system and a large number of service parties. The method for data transmission provided in this embodiment may be performed by a device for data transmission provided in the embodiment of the present invention, where the device may be implemented in a software and/or hardware manner, and is integrated in an electronic device that executes the method, where the device may be a data sending end that participates in data transmission, and the like.
Specifically, referring to fig. 1A, the method may include the steps of:
s110, dynamically updating the data state of each port in the set port array, and enabling the data state of at least one port in the port array to be a receivable state.
The service system provides network ports accessible to the public network for each service party, and a third party attacker can use the network ports to send forged message notifications to the service system to attack the service system. In order to solve the above problem, this embodiment may set a port array on the service system for receiving the asynchronous callback notification sent by each service party. As shown in fig. 1B, in this embodiment, each port (port) in the port array is correspondingly connected to a receiver, and is responsible for receiving data transmitted by each service party through the port connected to the receiver, so that the port array can form a transmission data receiving matrix.
Specifically, in order to ensure the data transmission security between the service system and each service party, in this embodiment, different data states are respectively configured for each port, where the data states may include a receivable state and a reception refusal state. For the data transmitted by the port in the receivable state in the port array, the service system receives the data and performs corresponding data processing, and for the data transmitted by the port in the refusal receiving state in the port array, the service system directly discards the data as the data forged by a third-party attacker.
In this embodiment, in order to prevent a third-party attacker from stealing a port in a receivable state in a port array and using the port to attack a service system, a data state of each port in the port array is typically dynamically configured, so that the ports in the receivable state and the determined receiving state in the port array are continuously dynamically updated, thereby increasing the difficulty that the port in the receivable state in the port array is stolen by the third-party attacker and improving the anti-counterfeiting strength of the service system for the third-party attacker.
For example, as shown in fig. 1B, the port array in this embodiment is connected to a matrix switch controller, and the matrix switch controller periodically controls the data state of each port in the port array, so that the time length of each port in the port array in the receivable state has a certain validity period, and in this embodiment, the validity period of each port in the port array in the receivable state may be represented by a validity time window, which is denoted as W.
Moreover, in order to ensure normal data transmission between the service system and each trusted service party, in this embodiment, when the data state of each port in the port array is dynamically updated, the data state of at least one port in the port array is in a receivable state, so as to avoid a situation that each port in the port array rejects to receive data, which results in a failure of normal data transmission.
In this embodiment, the number of ports in the port array that can be received at the same time can be usually set to at most two, so as to prevent the port array from being easily stolen by a third-party attacker when the number of ports in the receivable state at the same time is too large.
It should be noted that the port array in this embodiment may be a physical array, such as an antenna array or a wireless receiver, or an array composed of a plurality of different domain name addresses, or an array composed of different network ports, and the like, and the type of the port array is not limited in this embodiment, and includes but is not limited to the types provided above.
As an alternative in this embodiment, when the data state of each port in the port array is dynamically updated, a preset random algorithm may be adopted to dynamically update an available port in the port array, set the data state of the available port to a receivable state, and set the data state of the other ports in the port array except for the available port to a rejection state.
That is to say, in this embodiment, any one preset random algorithm may be adopted, each available port of the port array in the dynamic update period is randomly determined in each dynamic update period, the data state of each available port is set to be a receivable state, the data states of the other ports except the available port in the port array are set to be a rejection state, and then a new available port of the port array in the dynamic update period is continuously determined randomly by the preset random algorithm in the next dynamic update period, so that a cycle is performed, and dynamic update of the data state of each port in the port array is achieved.
Preferably, the random seed in the preset random algorithm may be a systematic white noise, such as but not limited to the following two types: and starting a current high-precision time stamp by the system, or randomly carrying out high-precision time of round-trip delay of certain communication and the like.
And S120, issuing the target port in the receivable state in the port array to the trusted data party, so that the trusted data party utilizes the target port to perform data transmission.
The trusted data party is each service party which has real service data transmission requirements with the service system.
After the data state of each port in the port array is dynamically updated, in order to ensure normal data transmission between the service system and each trusted data party, information of each target port in a receivable state after each dynamic update in the port array is respectively issued to each trusted data party, so that each trusted data party can accurately know the latest target port in the receivable state in the port array of the service system, and each trusted data party can perform data transmission with the service system by using each target port in the receivable state in the port array.
For example, to ensure the security issued by the target port, as shown in fig. 1B, in this embodiment, the service system actively establishes a corresponding one-way Secure encryption channel for each trusted data party, where the one-way Secure encryption channel may be a physical dedicated channel, or may also be a software encrypted virtual channel, for example, a Secure Socket Layer (SSL) Layer of a hypertext Transfer Protocol over Secure Socket Layer (HTTPS) that is targeted for security, or a software virtual encryption communication manner implemented in other similar manners, which is not limited in this embodiment, and only the one-way Secure encryption channel is required to enhance the issuing security of the target port.
At this time, the present embodiment may issue the target port in the receivable state in the port array to each trusted data party through the one-way secure encryption channel established for each trusted data party, so as to prevent the target port from being stolen by a third-party attacker. Moreover, the one-way secure encryption channel does not support each trusted data party to actively transmit data to the service system through the channel, so that a third-party attacker is prevented from actively constructing a corresponding secure encryption channel to the service system to transmit data forged by the third-party attacker, and the attack prevention degree of the service system is enhanced.
In this embodiment, since each trusted data party does not perform data transmission using the port in the denial of reception state in the port array, if the service system detects data received through the port in the denial of reception state, the data can be directly discarded as data forged by a third-party attacker, thereby enhancing the attack difficulty of the third-party attacker on the service system and improving the security of data transmission.
The technical solution provided in this embodiment may locally set a corresponding port array to receive data sent by other data parties, and at this time, by dynamically updating the data state of each port in the set port array, the data state of at least one port in the port array is made to be a receivable state, then the target port in the receivable state in the port array is issued to the trusted data party, so that the trusted data party can utilize the target port to transmit data, at the moment, a third party attacker is difficult to acquire the information of the target port in the receivable state in the port array, the counterfeiting difficulty of data transmission is enhanced, and the data transmission forged by the third party attacker is accurately prevented, on the basis of simplifying the layout of a data transmission structure by adopting a port array, the security of data transmission is further ensured, and a more efficient anti-counterfeiting attack effect is achieved.
Example two
Fig. 2A is a flowchart of a data transmission method according to a second embodiment of the present invention, and fig. 2B is a schematic diagram of a data transmission process according to the second embodiment of the present invention. The embodiment is optimized on the basis of the embodiment. Specifically, as shown in fig. 2B, the present embodiment mainly explains the specific processing procedure of data security transmission in detail.
Optionally, as shown in fig. 2A, the present embodiment may include the following steps:
s210, dynamically updating the data state of each port in the set port array, so that the data state of at least one port in the port array is a receivable state.
And S220, determining a port issuing cycle in the port array according to the port updating cycle of the port array and the data round-trip delay facing the trusted transmission party.
Optionally, considering that a certain data transmission delay exists when a target port in a receivable state is issued to each trusted data party, so as to avoid a problem that a trusted data party continues to use a failed target port before updating to perform data transmission in the data transmission delay after the port array is dynamically updated, and thus data transmission fails, in this embodiment, a data round-trip delay of the service system facing each trusted data party is determined, and then a port update cycle of the port array is correspondingly reduced by using the data round-trip delay of each trusted data party, so as to obtain a port issue cycle in the port array facing each trusted data party, so that the port issue cycle corresponding to each trusted data party can be smaller than the port update cycle of the port array, so that a corresponding target port can be issued to the trusted data party by using the port issue cycle corresponding to each trusted data party later, each trusted data party can timely know the target port in a receivable state after dynamic updating, and therefore the influence of data round-trip delay of each trusted transmission party when target port data is issued is reduced.
For example, if the port update period of the port array is denoted as W, and the round trip delay of a certain trusted data party is denoted as D, it may be determined that the trusted data party issues a period P < ═ W-6D for the port in the port array.
And S230, issuing the target port in the receivable state in the port array to the trusted data party, so that the trusted data party utilizes the target port to perform data transmission.
S240, if the first transmission data is received through other ports in the port array except the target port, recording data source information of the first transmission data in a preset blacklist.
Because the data transmitted by the third-party attacker and the trusted data party can be distinguished by judging whether the port adopted for data transmission is the target port in the receivable state or the port in the refusing receiving state in the port array, the embodiment can also carry out active defense on the third-party attacker.
Specifically, after receiving each transmission data through the port array, the present embodiment determines which port in the port array the transmission data is received by, so as to analyze the source information of the transmission data in the following. At this time, if the first transmission data is received through the other ports in the port array except the target port, it is indicated that the first transmission data is not sent by the trusted data party, and is most likely to be forged by a third party attacker, so that the data source information of the first transmission data is determined, and as shown in fig. 2B, the data source information is recorded in a preset blacklist as the identification information of the third party attacker, so that the preset blacklist is adopted to actively defend the third party attacker.
S250, if second transmission data are received through the target port in the port array, verifying data source information of the second transmission data by adopting a preset blacklist; and if the data source information of the second transmission data is recorded in the preset blacklist, discarding the second transmission data.
Because the third-party attacker may also randomly select the target port in a receivable state to transmit the forged data, when the second transmission data is received through the target port in the port array, the data source information of the second transmission data is also determined, then the data source information of the second transmission data is verified by using the preset blacklist, whether the data source information of the second transmission data is recorded in the preset blacklist is judged, if the data source information of the second transmission data is recorded in the preset blacklist, it is indicated that the second transmission data is also the data forged by the third-party attacker, and therefore the second transmission data is discarded. However, if the data source information of the second transmission data is not recorded in the preset blacklist, which indicates that the second transmission data is not forged by a third-party attacker, the second transmission data is used as data sent by a trusted data party to perform corresponding data processing.
S260, if the second transmission data is received through the target port in the port array, the second transmission data is verified by adopting a defined data anti-counterfeiting algorithm.
Optionally, in view of the fact that the attack difficulty of a third-party attacker on the service system is increased by dynamically updating the data state of each port in the port array in this embodiment, the method belongs to an improvement on a data transmission structure of the port array in the service system, and does not process actual transmission data itself, so that the trusted data party sends second transmission data to the service system through a target port in the port array to realize data security transmission, and performs security encryption processing on the sent second transmission data by using a defined data anti-counterfeiting algorithm, so that after the service system receives the second transmission data through the target port in the port array, the service system can further perform authenticity verification on the second transmission data by using the data anti-counterfeiting algorithm, and further improve the security of data transmission.
It should be noted that the data anti-counterfeiting algorithm in this embodiment may be a message anti-counterfeiting manner such as digital signature, information source binding, and the like. For example, the trusted data party needs to perform secure encryption processing on the second transmission data by using a digital signature technology to avoid tampering; then, after receiving the second transmission data through the port array, the service system needs to check whether the port where the second transmission data is located is legal or not, and further checks whether the signature of the second transmission data is correct or not on the basis that the applicable port is legal, thereby ensuring that the second transmission data is doubly and safely transmitted.
According to the technical scheme provided by the embodiment, for the first transmission data received by other ports except the target port in the port array, the data source information of the first transmission data is recorded in the preset blacklist, so that the preset blacklist is adopted to actively defend the data forged by the third-party attacker, the security of data transmission is further ensured, and the effect of more efficiently preventing the forging attack is achieved.
