Description

Field programmable logic gate array for financial transactions

The present invention relates to a field programmable logic gate array for financial transactions, and in particular to a field programmable logic gate array that achieves specific hardware acceleration purposes.

In the field of financial transactions, financial product brokers and investors are monitored and protected by the Financial Supervisory Commission. The trading of financial products must comply with the regulations of the Financial Supervisory Commission. Therefore, financial product brokers must effectively improve trading information under the conditions of meeting the regulations. speed and security.

However, existing financial transaction methods have shortcomings. Hackers can follow the content in transaction messages to attack investors or financial product brokers, causing user equipment or financial transaction servers to fail to work properly. Although additional firewall mechanisms can currently be used to provide protection, firewalls can easily cause a large amount of time delays in the process of forwarding transaction messages, which is also not conducive to financial transactions.

Furthermore, although the current trading system can have safe and fast computing capabilities, the computing function of the trading system relies on the efficiency of the central processing unit, and the central processing unit's message processing mechanism is limited by its own software, resulting in the central processor's inefficiency in message processing. The processing process cannot be carried out efficiently and quickly, which makes the possibility of optimizing the computing function of the conventional trading system limited. Therefore, the applicant of this case aims to solve the above-mentioned problems, so it accelerates the information processing speed through on-site programmable logic gate array to reduce the workload of the central processor and achieve the purpose of hardware acceleration.

There are currently published patents, such as CN 108183978B and TW 201926975A, which disclose the technology of using field programmable logic gate arrays to replace IP addresses (Internet Protocol Address). Take CN 108183978B as an example. After the communication equipment of CN 108183978B is started and the first IP address is read by the communication equipment, the on-site programmable logic gate array decides whether to replace the first IP address based on instructions from the host computer. However, it can be seen from the foregoing that the field programmable logic gate array disclosed in CN 108183978B must rely on instructions from the host computer. Once the instruction transmission from the host computer is delayed or incorrect, the field programmable logic gate array will not be able to work quickly. . Furthermore, when the field programmable logic gate array is in the process of receiving a message, it must receive the complete packet and then interpret the complete packet in sequence before it can read the first IP address. In this way, when the field programmable logic gate array When a customized logic gate array is used in a trading system, this on-site programmable logic gate array still cannot specifically achieve the purpose of hardware acceleration, which is not conducive to the financial transaction field where every second counts. Although TW 201926975A also discloses the technology of using a field programmable logic gate array to replace the header of the IP, TW 201926975A still has the problem of having to wait for the complete transmission and complete interpretation of the packet.

The main purpose of the present invention is to solve the problem that the existing financial transaction field cannot provide a trading system that can meet the specifications of the exchange, is safe and can operate quickly.

Another object of the present invention is to solve the problem that although the current field programmable logic gate array can accelerate the information processing speed, it still cannot achieve specific hardware acceleration.

To achieve the above object, the present invention provides a field programmable logic gate array for financial transactions, including a transceiver unit and a computing unit connected to the transceiver unit. The computing unit has an address replacement program, and the address replacement program has an associated memory of at least One initiator address corresponding to a transaction initiator, at least one execution end address corresponding to a transaction execution end, and an alternative initiation address associated with the transaction initiator, and the field programmable logic gate array serves as the transaction initiator A relay that transmits a transaction message packet with the transaction execution end, and uses the transceiver unit to receive the transaction message packet. The field programmable logic gate array has a relay address, and the computing unit performs the address replacement. The program sends at least one of the subsequent descriptions of the transaction message packet to the destination address described in the transaction message packet by an Internet layer in a TCP/IP protocol: (1) the source of the transaction message packet When it is marked as the initiator address, it is changed to the alternative initiator address; (2) When the destination of the transaction message packet is marked as the alternative initiator address, it is changed to the initiator address; (3) The transaction message packet When the destination is marked as the relay address, it is changed to the execution end address; (4) When the source of the transaction message packet is marked as the execution end address, it is changed to the relay address.

In one embodiment, the computing unit has a source confirmation program. When running, the source confirmation program compares whether a message source address included in the transaction message packet is one of the following: the initiator address, the execution terminal address, if it is to continue the address replacement process and allow the transaction message packet to pass, if not to prevent the transaction message packet from passing.

In one embodiment, the transceiver unit includes at least one message input port and at least one message output port.

In one embodiment, the computing unit includes two network address replacement modules connected to the message input port and the message output port respectively, and a computing module connected to the two network address replacement modules.

In one embodiment, the computing unit has a sending delay and a receiving delay, and the length of the sending delay is different from the length of the receiving delay.

Through the foregoing implementation of the present invention, compared with the conventional ones, it has the following characteristics: the field programmable logic gate array of the present invention has the address replacement program through the computing unit, so that the field programmable logic gate array does not need to interpret the complete Transaction message packet. When the transceiver unit receives the transaction message packet, the computing unit does not need to wait for the transaction message packet to be completely transmitted, but can directly perform the processing on the address contained in the transaction message packet at the Internet layer in the TCP/IP protocol. Replace.

The detailed description and technical content of the present invention are as follows with reference to the drawings: Please refer to Figure 1. The present invention provides a field programmable logic gate array 10. The field programmable logic gate array 10 is used in the field of financial transactions, and The field programmable logic gate array 10 can be installed in a servo device. The function of the field programmable logic gate array 10 is to provide hardware acceleration to increase the computing speed of the servo device and enable accelerated message processing during financial transactions.

Continuing with the above, please refer to Figures 1 to 4 again. The field programmable logic gate array 10 includes a transceiver unit 11 and an arithmetic unit 13. The transceiver unit 11 serves as the field programmable logic gate array 10 and external In the communication window, for example, the transceiver unit 11 can be connected to a user terminal device via an Internet 30, and the transceiver unit 11 receives information incoming from the user terminal device via the Internet 30. In one embodiment, the transceiver unit 11 includes at least one message input port 111 and at least one message output port 112. The message input port 111 is responsible for receiving information from the outside, and the message output port 112 is for transmitting messages to the outside. Just like Figure 8. The computing unit 13 is connected to the transceiver unit 11. Specifically, the computing unit 13 receives the message from the message input port 111, and transmits the processed message to the outside through the message output port 112.

Following the above, the computing unit 13 has an address replacement program 130. The address replacement program 130 associates and stores at least one initiator address 41, at least one execution end address 51, and a replacement initiator address. The initiator address The address 41 corresponds to a transaction initiator 40, which refers to a financial trader who establishes a financial transaction in the field of financial transactions. For example, The transaction initiator 40 may be the user terminal device held by a financial user, and the initiator address 41 may be the IP address of the user terminal device. The execution end address 51 corresponds to a transaction execution end 50. The transaction execution end 50 refers to a person who executes financial transactions in the field of financial transactions (such as a financial exchange, etc.). For example, the transaction execution end 50 can be the A financial transaction server of a financial exchange, and the execution end address 51 can be the IP address of the financial transaction server. The replacement initiation address is associated with the initiator address 41 . The replacement initiation address can be stored in the field programmable logic gate array 10 in advance, and can be correspondingly retrieved when the operation unit 13 is working.

Following the above, the field programmable logic gate array 10 serves as a relay station for transmitting a transaction message packet 20 between the transaction originator 40 and the transaction execution end 50, and the field programmable logic gate array 10 has a relay bit. site. The field programmable logic gate array 10 uses the transceiver unit 11 to receive the transaction message packet 20. When the transaction message packet 20 comes from the transaction initiator 40, the transaction message packet 20 describes the transaction initiator 40 to A transaction request made by the financial exchange. In addition, when the transaction message packet 20 comes from the transaction execution terminal 50, the transaction message packet 20 is used to describe the transaction execution result that the financial transaction server of the financial exchange intends to transmit to the transaction originator 40. . It can be seen from the above that the field programmable logic gate array 10 is only a relay in the transmission process of the transaction message packet 20 , and the actual transmission target of the transaction message packet 20 is the transaction initiator 40 or the transaction execution terminal 50 .

In addition, when the transceiver unit 11 receives the transaction message packet 20, the computing unit 13 does not need to wait for the transaction message packet 20 to be completely transmitted. The computing unit 13 can directly The address replacement program 130 is then executed. Specifically, the transaction message packet 20 of the present invention is transmitted based on a TCP/IP protocol. As informed by those skilled in the art, the TCP/IP protocol includes four layers, in order: Network Access Layer (Network). Access Layer), Internet Layer, Transport Layer and Application Layer. When the transceiver unit 11 receives the transaction message packet 20, the computing unit 13 does not need to completely interpret the transaction message packet 20 from the network access layer to the application layer. The computing unit 13 can When interpreting the Internet layer of the transaction message packet 20, the address replacement program 130 is directly executed. The computing unit 13 responds to the initiator address 41, the execution end address 51, At least one of the replacement initiating address and the relay address is replaced. Specifically, the computing unit 13 sends at least one of the subsequent descriptions of the transaction message packet 20 to the target address described in the transaction message packet 20: (1) The source of the transaction message packet 20 is marked as the originator When the end address is 41, it is changed to the replacement origination address; (2) When the target of the transaction message packet 20 is marked as the replacement origination address, it is changed to the origination end address 41; (3) The transaction message packet 20 When the destination is marked as the relay address, it is changed to the execution end address 51; (4) When the source of the transaction message packet 20 is marked as the execution end address 51, it is changed to the relay address.

Continuing with the above, please refer to FIGS. 1 to 4 again to describe the implementation of the field programmable logic gate array 10 . For the convenience of explanation later, this article first assumes that the originating end position The address 41 is 78.78.78.78, the execution end address 51 is 192.168.2.3, the relay address is 10.3.4.5, and the replacement initiation address is 10.111.57.161.

In the following, the transaction initiator 40 will submit a transaction request explanation to the transaction execution terminal 50 . At this time, the source of the transaction message packet 20 is the transaction initiator 40. The field programmable logic gate array 10 receives the transaction message packet 20 through the transceiver unit 11. The computing unit 13 receives the transaction through the transceiver unit 11. During the process of transmitting the message packet 20, the computing unit 13 does not completely interpret the transaction message packet 20, that is, the computing unit 13 does not need to completely interpret the four layers included in the TCP/IP protocol. When entering the Internet layer of the transaction message packet 20, the computing unit 13 executes the address replacement procedure 130. At this time, the computing unit 13 changes the source of the transaction message packet 20 from the originator address (label 41) to 78.78. .78.78 is replaced with the replacement initiation address 10.111.57.161, and then the computing unit 13 continues to transmit the replaced transaction message packet 20 to the transceiver unit 11, so that the transaction execution terminal 50 receives the replaced transaction message. Packet 20. When the transaction execution terminal 50 intends to return the execution result to the transaction initiation terminal 40, the destination of the transaction message packet 20 sent by the transaction execution terminal 50 is marked as the replacement initiation address 10.111.57.161. At this moment, the computing unit 13 executes the address replacement program 130 again, so that the target indicated in the transaction message packet 20 is changed from the replacement initiating address 10.111.57.161 to the initiating end address (label 41) 78.78.78.78 .

In another implementation, when the transaction initiator 40 transmits the transaction message packet 20 to the transaction execution terminal 50, the field programmable logic gate array 10 As a relay between the transaction initiator 40 and the transaction execution end 50, the transceiver unit 11 receives the transaction message packet 20. At this time, the destination marked by the transaction message packet 20 is the relay address, and during the process of the transceiver unit 11 receiving the transaction message packet 20, the computing unit 13 does not fully interpret the transaction message packet 20 , that is, the computing unit 13 does not need to completely interpret the four layers included in the TCP/IP protocol. When the computing unit 13 interprets the Internet layer of the transaction message packet 20, the computing unit 13 executes the address Replacement procedure 130. The computing unit 13 replaces the destination indicated in the transaction message packet 20 from the relay address 10.3.4.5 to the execution end address (label 51) 192.168.2.3, and then the computing unit 13 replaces the replaced transaction The message packet 20 is continuously transmitted to the transceiver unit 11, so that the transaction execution terminal 50 receives the replaced transaction message packet 20. When the transaction execution terminal 50 intends to return the execution result to the transaction initiator 40, the source of the transaction message packet 20 sent by the transaction execution terminal 50 is marked as the execution terminal address (label 51) 192.168.2.3. The computing unit 13 executes the address replacement program 130 again, so that the source indicated in the transaction message packet 20 is changed from the execution end address (label 51) 192.168.2.3 to the relay address 10.3.4.5.

Following the above, the applicant in this case also called the replacement originating address or the relay address Vincent IP. Through the design of the address replacement program 130, at least one of the source and destination marked in the transaction message packet 20 can be replaced to achieve a tattoo-like effect. When the transaction execution terminal 50 returns the transaction message packet 20, the computing unit 13 can reply to at least one of the source and destination indicated in the transaction message packet 20, so that the transaction message packet 20 can still comply with financial transaction standards. . Furthermore, the present invention is To ensure the security of the transmission of the transaction message packet 20 and prevent the transaction initiator 40 or the transaction execution end 50 from being attacked by the network, the on-site programmable logic gate array 10 of the present invention is not implemented by establishing an additional firewall, which can reduce the risk of network attacks. Delay caused by firewall. Furthermore, the computing unit 13 of the present invention has the address replacement program 130. When executing the address replacement program 130, the computing unit 13 does not need to completely interpret the transaction message packet 20. The computing unit 13 only needs to retrieve the transaction. The Internet layer of the message packet 20 replaces the initiator address 41 or the replacement address, thereby allowing the field programmable logic gate array 10 to share part of the operations during implementation to achieve hardware acceleration effect.

Please refer to FIG. 5 and FIG. 6 again. In one embodiment, the computing unit 13 has a source confirmation program 133. When the source confirmation program 133 is executed, the computing unit 13 compares a message contained in the transaction message packet 20. Source address 21. Specifically, the message source address 21 corresponds to the IP address of the initiator of the transaction message packet 20. For example, when the transaction message packet 20 is submitted by the transaction initiator 40, the message source of the transaction message packet 20 The address 21 is the initiator address 41 of the transaction initiator 40. For example, when the initiator address 41 is 78.78.78.78, the message source address 21 of the transaction message packet 20 is represented as 78.78.78.78. When the transaction message packet 20 is submitted by the transaction execution terminal 50, the message source address 21 of the transaction message packet 20 corresponds to the execution terminal address 51 of the transaction execution terminal 50, for example, the execution terminal address When 51 is 192.168.2.3, the message source address 21 of the transaction message packet 20 is represented as 192.168.2.3. Further, the computing unit 13 compares whether the message source address 21 of the transaction message packet 20 is one of the following groups: the The initiator address 41 and the execution end address 51, if so, continue the address replacement procedure 130 and allow the transaction message packet 20 to pass; otherwise, the transaction message packet 20 is blocked from passing. Taking FIG. 5 as an example, it can be seen that when the message source address 21 of the transaction message packet 20 matches the initiator address 41, the computing unit 13 continues the address replacement process 130 and causes the transaction message packet 20 to be delivered to The transaction execution end 50; conversely, when the message source address 21 does not match the initiator address 41, the computing unit 13 blocks the transaction message packet 20 from passing through, as shown in Figure 6. It can be seen from this that the present invention enables the field programmable logic gate array 10 to achieve risk control through the design of the source confirmation program 133, and allows the transaction message packet 20 to be managed without reducing the message transmission rate.

Continuing with the above, please refer to FIG. 7 . In another embodiment, the field programmable logic gate array 10 of the present invention can also be implemented with a plurality of fire protection devices 60 , and at least one of the fire protection devices 60 is disposed on Between the field programmable logic gate array 10 and the transaction initiator 40 , at least one other of the fire protection devices 60 is disposed between the field programmable logic gate array 10 and the transaction execution terminal 50 . between lines. In other words, after the transaction initiator 40 proposes the transaction message packet 20, the transaction message packet 20 is transmitted to at least one of the fire protection devices 60 through the Internet 30, and the fire protection devices 60 receive the message from the fire protection device 60. After receiving the transaction message packet 20 from the transaction initiator 40, preliminary risk management is provided for the transaction message packet 20, and then the transaction message packet 20 is delivered to the transceiver unit 11. In addition, after the transaction execution terminal 50 sends the transaction message packet 20, the transaction message packet 20 is delivered to the defense At least one other of the fire protection devices 60. After receiving the transaction message packet 20 from the transaction execution end 50, these fire protection devices 60 provide preliminary risk management for the transaction message packet 20, and then process the transaction message. The packet 20 is delivered to the transceiver unit 11 . In this implementation, the fire protection devices 60 provide basic risk management for the field programmable logic gate array 10 and can allow or restrict the passage of the transaction message packet 20 .

Continuing with the above, please refer to Figure 8. The computing unit 13 includes two network address replacement modules 131 and one computing module 132. The two network address replacement modules 131 are respectively connected to the message input port 111 and the message output. Port 112, the two network address replacement modules 131 can provide the computing unit 13 to execute the address replacement program 130, and the computing module 132 is connected to the two network address replacement modules 131, and can replace the transaction The originator address 41 of the message packet 20 and the replacement address. Furthermore, in another embodiment, one of the two network address replacement modules 131 receives the transaction message packet 20 from the message input port 111. The person connected to the message input port 111 executes the address replacement procedure 130 on the transaction message packet 20, which comes from the transaction initiator 40, and the two network address replacement modules 131 are connected During the execution of the message input port 111, the computing unit 13 has a receiving delay. For example, the receiving delay is 32 milliseconds. In addition, the other of the two network address replacement modules 131 receives the transaction message packet 20 from the message output port 112, and the one of the two network address replacement modules 131 connected to the message output port 112 Execute the address replacement procedure 130 on the transaction message packet 20, which comes from the transaction execution end 50, and the one of the two network address replacement modules 131 connected to the message output port 112 is During execution, the computing unit 13 is allowed to have a sending delay, the length of which is different from the receiving delay. duration. For example, the sending delay is 44.8 milliseconds, which is longer than the receiving delay.

To sum up, the above is only a preferred embodiment of the present invention. It should not be used to limit the scope of the present invention. That is, all equivalent changes and modifications made according to the patent scope of the present invention should still belong to the present invention. patent coverage.
