Detailed Description

In order to make those skilled in the art better understand the technical solutions in one or more embodiments of the present disclosure, the technical solutions in one or more embodiments of the present disclosure will be clearly and completely described below with reference to the drawings in one or more embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, and not all embodiments. All other embodiments that can be derived by a person skilled in the art from one or more of the embodiments described herein without making any inventive step shall fall within the scope of protection of this document.

Fig. 1 is a flowchart illustrating an address tracing method according to one or more embodiments of the present disclosure, where the method in fig. 1 can be executed by an address tracing apparatus, and the address tracing apparatus may be disposed in a terminal device or a server. The terminal device can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like. The server side can be an independent server or a server cluster consisting of a plurality of servers. As shown in fig. 1, the method may include the steps of:

step S102, determining an onion routing node accessed to a resource transaction network;

wherein the resource trading network is a peer-to-peer, decentralized trading network. The resource transaction network may be a transaction network of any resources, such as virtual resources (e.g., electronic or digital resources available for transactions, such as points, etc.), physical resources (e.g., funds, etc.), physical resources (e.g., bandwidth, etc.), and so on.

The onion routing Tor is an implementation of the onion routing protocol (onion routing) by which a user can communicate anonymously in a network. Specifically, when the user uses Tor, a transmission chain is generally formed by using three Tor relay nodes as communication agents; and negotiating a session key with three relay nodes on a transmission chain in sequence by using a public key encryption mode. In the communication process, firstly, a sending end carries out three-layer encryption on data, and the data are sequentially transmitted to a target end through three selected relay nodes. When the encrypted data reaches one relay node, the relay node performs one-layer decryption through the negotiated key to acquire the IP address of the next relay node and continues to transmit. In the whole transfer process, each relay node can only know the IP addresses of the nodes adjacent to the relay node, but cannot simultaneously know the IP addresses of the sending end and the target end, so that anonymous data transmission is realized. The last relay node of the transmission chain may also be referred to as an egress node (exit node), from which data comes for the destination. When the target transmits data to the initiator, the data is also from the egress node to the initiator. For resource transaction based on the onion routing, a transaction client (i.e., a sending end) of a user broadcasts transaction data to a resource transaction network (i.e., a destination end) through an egress node, which is an onion routing node accessing the resource transaction network in step S102, corresponding to a transmission chain.

Step S104, attack processing is carried out on the onion routing node, so that the transaction client connected with the onion routing node is disconnected with the onion routing node, and transaction is initiated in the resource transaction network based on the plaintext IP address of the transaction client;

when the transaction client is disconnected from the onion routing node, the transaction client initiates a transaction in the resource transaction network based on the own plaintext IP address in order to ensure timely and effective transaction. At the moment, the plaintext IP address of the transaction client can be traced, so that the identity of the transaction client can be identified based on the IP address, whether the corresponding transaction has designated risks or not can be detected, and illegal transactions can be avoided.

And step S106, tracing the plaintext IP address corresponding to the original transaction client of the target transaction in the resource transaction network according to a preset tracing mode.

Wherein the target transaction is a transaction initiated in the resource transaction network based on the plaintext IP address for the first time.

In one or more embodiments of the present description, after determining an onion routing node accessing a resource transaction network, attack the onion routing node to disconnect a transaction client connected to the onion routing node from the onion routing node, and initiate a transaction in the resource transaction network based on a plaintext IP address of the transaction client; and tracing the plaintext IP address corresponding to the originating transaction client of the target transaction in the resource transaction network according to a preset tracing mode. Therefore, the determined onion routing node is attacked, so that the corresponding transaction client initiates a transaction in the digital transaction network through the own plaintext IP address, and the source tracing processing can be performed on the plaintext IP address corresponding to the originating transaction client of the target transaction. The clear text IP tracing of the anonymous network is realized, and further the identity identification of a transaction party is realized; not only is beneficial to the continuous and effective development of maintenance online transactions, but also has positive promotion effect on the stabilization of the economy and the society.

It is considered that in the resource trading network, the access information of each access node is transparent. In one or more embodiments of the present description, the onion routing node is determined based on the access information. Specifically, as shown in fig. 2, step S102 may include the following steps S102-2 to S102-6:

step S102-2, acquiring access information of each access node of the current access resource transaction network according to a preset time interval;

optionally, the address tracing device accesses the resource transaction network, and acquires access information of each access node currently accessing the resource transaction network according to a preset time interval. Or the address tracing device does not access the resource transaction network, and sends an access information acquisition request to a specified access node accessing the resource transaction network according to a preset time interval, and receives the access information sent by the specified access node. The preset time interval can be set as required in practical application, for example, 10 minutes. Since the resource trading network is a P2P (peer-to-peer) network, each access node currently accessing the resource trading network includes a trading client and/or an onion routing node that initiates a transaction based on a clear IP address. The access information may include information such as access address, area in which the access node is located, etc.

Step S102-4, determining whether target access information meeting preset rules exists in the access information;

specifically, an access address is acquired from each piece of access information, and whether the acquired access address meets a preset rule or not is determined; if so, determining that the target access information exists, and determining the access information where the access address which meets the preset rule is located as the target access information. The preset rule may include a preset format, a preset character, and the like.

And step S102-6, if yes, determining the access node corresponding to the target access information as an onion routing node.

Since in a resource trading network the access information of each access node is transparent and the access address is usually included in the access information. Therefore, by acquiring the access information of each access node, the onion routing node can be accurately determined based on the access information.

In the resource transaction network, when a transaction client receives a message with an incorrect format, a sending node of the message with the incorrect format is punished, and when the punishment score exceeds a preset score, the IP address of the sending node is prohibited from being connected to the resource transaction network within a preset time (for example, 24 hours). Based on the above, in one or more embodiments of the present specification, attack processing is performed on the determined onion routing node, so that a transaction client connected to the onion routing node performs penalty processing on the onion routing node until the connection with the onion routing node is disconnected. Specifically, as shown in fig. 3, the step S104 may include the following steps S104-2 and S104-4:

step S104-2, according to the access address in the target access information, establishing connection with the corresponding onion routing node;

and step S104-4, sending a preset attack message to the onion routing node through the established connection, so that the onion routing node sends the attack message to a corresponding transaction client, the transaction client punishs the onion routing based on the attack message, and when the onion routing node is determined to meet the preset disconnection condition, the onion routing node is disconnected.

In the onion routing, a sending end sends data to a target end through an exit node, and the target end also sends the data to the sending end through the exit node. And the determined onion routing node is an exit node corresponding to the corresponding transaction client, so that the address tracing device establishes connection with the onion routing node and sends a preset attack message to the onion routing node through the established connection. When the onion routing node receives the attack message, the onion routing node sends the attack message to a corresponding transaction client; when the transaction client receives the attack message sent by the onion routing node, punishment processing is carried out on the onion routing node if the error message is determined, and when the preset disconnection condition is determined to be met (for example, the punishment score reaches the preset score), the connection with the onion routing node is disconnected. It should be noted that the address tracing apparatus may send the attack message of the preset byte amount to the determined onion routing node at one time, so that when the transaction client receives the attack message of the preset byte amount, the transaction client performs penalty processing and determines that the preset disconnection condition is satisfied, and disconnects the connection with the onion routing node. The address tracing device can also continuously send a plurality of attack messages to the onion routing nodes, correspondingly, the client punishment processing is carried out on the onion routing nodes when receiving each attack message, and the connection with the onion routing nodes is disconnected when the client determines that the preset disconnection condition is met. The specific sending mode of the attack message can be set in practical application according to the requirement.

Therefore, by sending the attack message to the onion routing node, the corresponding transaction client can be disconnected from the onion routing node, and a transaction can be initiated in the resource transaction network through the plaintext IP address of the transaction client; therefore, the source tracing processing can be carried out on the plaintext IP address corresponding to the transaction client of the target transaction in the resource transaction network, so as to maximally trace the plaintext IP address of the transaction client which initiates the transaction based on the onion route. Specifically, as shown in fig. 4, the step S106 may include the following steps S106-2 to S106-6:

step S106-2, acquiring transaction data broadcast by each access node accessed to the resource transaction network;

step S106-4, if the transaction data which is obtained is determined to be obtained for the first time based on the cached historical transaction data, caching the obtained transaction data, determining an access node which broadcasts the transaction data as an initial node of the transaction data, and determining target address information of the initial node;

in the resource transaction network, transaction data may be forwarded for multiple times, so that in order to determine an originating node of the transaction data, the transaction data acquired for the first time is cached, and when the transaction data broadcasted to the resource transaction network is acquired each time, the acquired transaction data is matched with the cached transaction data, if the matching fails, the acquired transaction data is determined to be acquired for the first time, the broadcasting node of the transaction data is determined to be the originating node of the transaction data, and target address information of the originating node is acquired from the acquired transaction data. If the matching is successful, the acquired transaction data is determined not to be acquired for the first time, namely the transaction data is forwarded transaction data.

Further, in order to ensure the accuracy of the originating node, in one or more embodiments of the present specification, the determining the access node broadcasting the transaction data as the originating node of the transaction data in step S106-4 may include:

evaluating each access node accessed to the resource transaction network according to a preset evaluation mode to obtain a candidate node of the initial transaction data; determining whether the candidate node and an access node for broadcasting transaction data are the same node; if yes, determining the node broadcasting the transaction data as an originating node; if not, the candidate node is determined as the originating node. In one embodiment, the evaluation process may be performed on each access node accessing the resource transaction network by using a maximum likelihood probability evaluation method. It should be noted that the evaluation method in this specification is not particularly limited, and may be set as needed in practical applications.

Step S106-6, if the target address information is determined to be not in accordance with the preset rule and the target address information is not included in the designated information base, determining the transaction corresponding to the transaction data as the target transaction, determining the originating node as the originating transaction client of the target transaction, and determining the target address information as the plaintext IP address of the originating transaction client.

Specifically, whether the target address meets a preset rule is determined, and if not, whether the specified information base comprises target address information is determined; if the target address information is not included, determining the transaction corresponding to the transaction data as a target transaction, determining the corresponding originating node as an originating transaction client of the target transaction, and determining the target address information as a plaintext IP address of the originating transaction client. And if the transaction data comprises the target address information, determining that the plaintext IP address of the transaction client corresponding to the transaction data is traced. The designated information base may include an association relationship between plaintext IP address information of a plurality of transaction clients and account information.

Further, as shown in fig. 5, the method may further include the following steps S106-8 and S106-10:

step S106-8, if the target address information is determined to accord with the preset rule, determining that the originating node is a new onion routing node newly accessed to the resource transaction network;

because a certain time difference often exists between the attack processing and the transaction data acquisition, and a new onion routing node may be accessed to the resource transaction network within the time difference, that is, when the target address information is determined to meet the preset rule, the corresponding originating node is determined to be a new onion routing node newly accessed to the resource transaction network.

And step S106-10, carrying out attack processing on the new onion routing node so as to disconnect the transaction client connected with the new onion routing node from the new onion routing node, initiating transaction in the resource transaction network based on the plaintext IP address of the transaction client, and returning to step S106-2.

Optionally, after determining a new onion routing node, performing attack processing on the new onion routing node; or when the preset time interval is reached, carrying out attack processing on the new onion routing node and each determined onion routing node. The process of performing attack processing on the new onion routing node is the same as the process of performing attack processing on the onion routing node, and reference may be made to the foregoing related description, and repeated details are not repeated here.

Furthermore, a data basis for matching can be provided when tracing the plaintext IP address in the following process. As shown in fig. 6, in one or more embodiments of the present specification, after step S106, the following step S108 may be further included:

step S108, determining account information of the original transaction client, and storing the account information and the plaintext IP address corresponding to the original transaction client into a specified information base in a correlated manner.

Specifically, account information of the original transaction client is obtained from the transaction data, and the account information and a plaintext IP address corresponding to the original transaction client are stored in a specified information base in a correlated manner. The account information represents the identity of the transaction party corresponding to the transaction client, so that after the plaintext IP address is traced, the plaintext IP address and the account information are stored in an associated manner, which is equivalent to identifying the identity of the transaction party corresponding to the plaintext IP address.

Considering that the originating client corresponding to the transaction data may be a transaction client that previously initiated a transaction through the onion routing node, in order to avoid an illegal transaction, as shown in fig. 7, in one or more embodiments of the present specification, the following step S110 may be further included after step S106:

and step S110, carrying out risk detection processing on the target transaction according to a preset risk detection mode.

In one embodiment, transaction data of a target transaction is input into a preset risk detection model, so that risk detection processing is performed on the target transaction through the risk detection model to obtain risk detection result information. It should be noted that, as to the specific form of the risk detection method, the present specification is not particularly limited, and the risk detection method may be set in an actual application as needed.

Further, when the risk detection result information indicates that the target transaction has a specified risk, the method may further include: and carrying out risk prompt processing so as to enable the related nodes to stop the transaction processing of the target transaction.

On the basis of the same technical concept, corresponding to the address tracing method described above, another address tracing method is provided in one or more embodiments of the present specification, fig. 8 is a schematic flow diagram of another address tracing method provided in one or more embodiments of the present specification, and the method in fig. 8 can be executed by a block chain system; as shown in fig. 8, the method comprises the steps of:

step S202, determining onion routing nodes of an access block chain network;

the process of initiating a transaction in the blockchain network by the blockchain client through the onion routing node is the same as the process of initiating a transaction in the resource transaction network by the transaction client through the onion routing node, and reference may be made to the foregoing related description, and repeated details are not repeated here.

Step S204, attack processing is carried out on the onion routing node, so that the blockchain client connected with the onion routing node is disconnected with the onion routing node, and transaction is initiated in a blockchain network based on the plaintext IP address of the blockchain client;

the implementation process of this step is the same as the implementation process of step S104, and reference may be made to the related description, and repeated details are not repeated here.

Step S206, tracing the plaintext IP address corresponding to the originating blockchain client of the target transaction in the source blockchain network based on the first intelligent contract deployed in the blockchain network.

Specifically, if transaction data broadcasted by an access node of an access blockchain network is acquired, a first intelligent contract deployed in the blockchain network is called, if the acquired transaction data is determined to be acquired for the first time according to cached historical transaction data based on the first intelligent contract, the acquired transaction data is cached, the access node broadcasting the transaction data is determined to be an originating node of the transaction data, and target address information of the originating node is determined; if the target address information is determined to be not in accordance with the preset rule and the block chain does not include the target address information, determining the transaction corresponding to the transaction data as a target transaction, determining the originating node as an originating transaction client of the target transaction, and determining the target address information as a plaintext IP address of the originating transaction client.

Further, in order to provide data basis for subsequent IP tracing, step S206 may further include:

and determining account information of the originating blockchain client, and storing the determined account information and the plaintext IP address corresponding to the originating blockchain client in a specified storage position in an associated manner. The designated storage location may be in a block chain or in a designated information base.

Considering that the originating blockchain client corresponding to the transaction data may be a blockchain client that previously initiated a transaction through the onion routing node, in order to avoid an illegal transaction, step S206 may further include:

and calling a second intelligent contract deployed in the blockchain network, and carrying out risk detection processing on the target transaction based on the second intelligent contract.

Further, in order to facilitate tracing the risk detection process, the method may further include: and generating risk detection record information according to a risk detection result obtained by the risk detection processing, and storing the risk detection record information into the block chain.

In one or more embodiments of the present description, after determining an onion routing node accessing a blockchain network, attack the onion routing node to disconnect a blockchain client connected to the onion routing node from the onion routing node, and initiate a transaction in the blockchain network based on a plaintext IP address of the blockchain client; tracing a plaintext IP address corresponding to an originating blockchain client of a target transaction in a source blockchain network based on a first intelligent contract deployed in the blockchain network. Therefore, the determined onion routing node is subjected to attack processing, so that the corresponding blockchain client initiates a transaction in the blockchain network through the own plaintext IP address, and the source tracing processing can be performed on the plaintext IP address corresponding to the originating blockchain client of the target transaction. The clear text IP tracing of the anonymous network is realized, and further the identity identification of a transaction party is realized; the method is not only beneficial to the continuous and effective development of maintaining the block chain transaction, but also has positive promotion effect on ensuring the stability of economy and society. In addition, the source tracing processing of the IP address is carried out based on the intelligent contract, and the effectiveness of the source-traced plaintext IP address can be guaranteed based on the characteristics that the intelligent contract is automatically executed and cannot participate artificially.

Therefore, the determined onion routing node is subjected to attack processing, so that the corresponding blockchain client initiates a transaction in the blockchain network through the own plaintext IP address, and the source tracing processing can be performed on the plaintext IP address corresponding to the originating blockchain client of the target transaction. The clear text IP tracing of the anonymous network is realized, and further the identity identification of a transaction party is realized; the method is not only beneficial to the continuous and effective development of maintaining the block chain transaction, but also has positive promotion effect on ensuring the stability of economy and society. In addition, the source tracing processing of the IP address is carried out based on the intelligent contract, and the effectiveness of the source-traced plaintext IP address can be guaranteed based on the characteristics that the intelligent contract is automatically executed and cannot participate artificially.

The foregoing description has been directed to specific embodiments of this disclosure. 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 require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may also be possible or may be advantageous.

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 that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using 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, 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.

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.
