Description

ETC fee deduction system fee deduction method based on remote deployment of PSAM card, ETC fee deduction control device and system

Technical Field

The invention relates to the field of intelligent traffic charging systems, in particular to a method for deducting fees of an ETC fee deduction system based on a remote deployment PSAM card, ETC fee deduction control equipment and a system.

Background

The POS terminal security access module (PSAM) is in the form of a solid card, the card stores a related key and can perform key operation, and the upper system needs to operate a corresponding Chinese financial Integrated Circuit (IC) according to the key return information. The multi-application card issuing system is mainly used for equipment such as commercial POS, network point terminals and direct connection terminals, has a safety control management function, supports a multi-stage card issuing mechanism, and is suitable for multi-application environments. The PSAM card conforms to the Chinese financial integrated circuit (IC card) PSAM card specification. The Chinese financial Integrated Circuit (IC) card (hereinafter referred to as IC card) is in the form of solid card, and conforms to the Chinese financial Integrated Circuit (IC) card specification, card memory discharge sub-wallet or electronic bankbook. The consumption and load operation of the electronic purse or the electronic bankbook can be successful only by obtaining the decryption information of the PSAM card storing the corresponding key. The encryption machine (cipher machine) is a computer which is specially used for storing cipher or cipher key and providing correspondent service, and the production and sale of said computer must be in accordance with the related national standard, and can be approved by related national departments, and can be sold and used.

The intelligent traffic system is mainly divided into three parts: a charging system, a communication system and a monitoring system. At present, a charging system in an intelligent traffic system is mainly based on the information technology of a general electronic computer, such as a database technology, a TCP/IP network technology, a JAVA technology, a C + + technology and the like; specialized traffic technical standards, such as technical requirement for temporary highway networking toll collection issued by the department of transportation; the specialized financial encryption technology standard, such as the electronic toll collection CPU card data format and technical requirements issued by the department of transportation.

In an IC card consumption scene related to intelligent transportation, the whole related system is divided into a terminal consumption system and a background settlement system. In a consumption site, a terminal consumption system is deployed, comprising: a consumption software system, a communication system, an IC card read-write device, a network device and the like. In the remote center background, a background settlement system is deployed, which comprises: IC card issuing system, IC card transaction flow settlement system, database server, network equipment, etc. The transaction flow is as follows: the user consumes, uses the IC card to trade on the read-write equipment (card reader or antenna), the trade information is decrypted and verified by the local PSAM or the encryption machine at different places, the system deducts the fee and writes the information on the card after obtaining the decryption and verification information, forms the trade flow and uploads to the IC card trade flow settlement system disposed in the IC card issuing organization (or the authorization organization thereof) through the network, carries on the trade settlement, carries on the fund transfer after the settlement is finished.

At present, in the traffic field such as expressways, parking lots, gas stations and the like, the IC card is used for carrying out operations such as money consumption, earmark or information reading and writing. When such an operation is performed, the data information decryption verification operation must be performed in the IC card, and the key for decryption verification is not stored in the IC card. But is stored in another PSAM card or in an encryption engine. Every time the IC card is consumed, earmarked or read and written, the IC card must perform data interaction with a PSAM card or an encryption machine, the PSAM card or the encryption machine performs key calculation, and then the system performs decryption verification on the IC card data to complete the operation of the IC card.

At present, there are two main ways for data interaction requiring key participation, one is to place a PSAM card read/write device in a place (place) where an IC card is consumed or in a nearby building, and usually the PSAM card read/write device and the IC card read/write device are the same device. The key for decryption and verification is provided by a PSAM card, the PSAM card is placed in a card reader, the card reader is arranged in a consumption site and is in wired connection (usually in serial connection) with terminal charging system equipment, when the terminal charging system conducts transaction, read IC card information is sent to the PSAM card in the card reader through a serial port for decryption and verification, after a result is obtained, deduction and writing of an IC card are completed, and then transaction flow is formed and uploaded to an IC card transaction flow settlement system in a different place for settlement. The other is to place an encryption machine in the IC card issuing organization (or the authorization organization thereof) of each province, and the IC card read-write device and the encryption machine are in a different-place relationship and can cross the city or province. The cipher key for decryption and verification is provided by the encryptor, the encryptor is arranged at the IC card issuing organization (or the authorization organization thereof) at different places, the terminal charging system is connected with the encryptor by a remote network, when the terminal charging system carries out transaction, the read IC card information is sent to the encryptor at different places by a serial port for decryption and verification, after a remote return result is obtained, the deduction and writing of the IC card is completed, and then transaction flow is formed and uploaded to the IC card transaction flow settlement system at different places for settlement.

The first scheme has the disadvantages that the PSAM card must be scattered at each IC card consumption place (or nearby), so that the PSAM is scattered in a large number of places, the management and the preservation of the PSAM entity card are taken charge of by a unit belonging to a consumption scene, the management is difficult, the loss risk is high, and the PSAM card can be subjected to PSAM-related illegal operations by lawless persons after being lost, so that the IC card holder and the IC issuing organization can be subjected to unpredictable loss. And the consumption terminal system is connected with the PSAM card by adopting a serial port, so that the transaction cannot be finished in different places. However, the PSAM card has the advantages that the PSAM card is a nationwide key, and the IC cards issued by different issuers of different provinces can be decrypted and verified. The second scheme has a disadvantage that the secret key of each provincial IC card issuer in the encryptor can only decrypt and verify the IC card issued by the institution, but cannot decrypt and verify the IC cards issued by different provincial IC card issuers nationwide. If the consumption scene needs to decrypt the nationwide IC card, the IC card must interact with an encryption machine with a nationwide key, and the IC issuing organizations of provinces cannot provide the service at the moment, so that the dominance of the service is indirectly lost.

Each process requires remote network access. At present, the traditional ETC fee deduction does not have the logic concept of PSAM access service equipment, and the three processes are integrated into one or two complete commands to be provided for external service system calling, and the traditional approach is short-distance communication (serial ports and the like) instead of a remote network. The non-splitting command can not be called on the network to complete the complete ETC fee deduction, because the fee deduction process is three-party interaction of an ETC card, fee deduction control equipment and a PSAM card, the current method is that all logics are placed in the fee deduction control equipment, and the fee deduction control equipment, the ETC card and the PSAM card adopt short-distance communication (serial ports and the like), so that the transmission and the interaction on the network are difficult to split.

Compared with the prior art, the invention has the beneficial effects that:

(1) the PSAM cards can be intensively deployed in a professional field instead of being deployed on the site of a fee deduction scene, so that the PSAM cards originally deployed in all parts of the country can be uniformly deployed in one place, strict management can be specially carried out, and the risk of losing the PSAM cards is avoided.

(2) The ETC card read-write equipment and the PSAM card read-write equipment can be separated remotely, compared with the prior art that the ETC card read-write equipment and the PSAM card read-write equipment are in the same equipment or in the same local area network, the ETC fee deduction scene does not need to store or manage the PSAM card, and the defects that the PSAM card can only be deployed in a short range and the like are overcome.

(3) The system and the method of the invention adopt the uniform PSAM card access service equipment to carry out access management on the PSAM card, thereby avoiding the risk of illegal use of the PSAM card.

(4) The interactive process between the PSAM card and the ETC card read-write equipment of the fee deducting system is carried out through a remote network of the PSAM card access service equipment, the process comprises decomposition and recombination of instructions, addition and verification of error correction information, sending, receiving, retransmitting and the like, and the whole process needs to be guaranteed to be within the specified time delay of an external service system.

(5) The fee deduction system of the invention adopts the PSAM card to encrypt and decrypt the ETC card instead of adopting the encryption machine, so that the ETC fee deduction system can support the ETC cards issued all over the country, and most of the encryption machines of the high-speed management centers all over the country only have the keys of the province, only can support the ETC cards issued by the province, and cannot support the ETC cards all over the country, therefore, the system and the method greatly increase the flexibility of service and the market value of popularization.

referring to fig. 2 and 3, when the external service system sends a deduction request to the ETC deduction control device, the deduction request includes identification information of the deducted subject (such as license plate, or ETC card number) and the amount of the deduction;

the ETC fee deduction control device reads first ciphertext information of an OBU (on-board unit) or an ETC (electronic toll collection) card through the ETC card reading device after acquiring the identification information, then sends the first ciphertext information to the PSAM card access service device through a remote network to request the PSAM card to decrypt, adds first error correction information in the sending process, resends the first ciphertext information if an opposite side returns an error or an overtime error, fails the whole fee deduction process if the number of errors is too many, and returns the error to an external service system.

The PSAM card access service equipment checks error correction information after receiving the decryption request, if the check is wrong, first check failure information is replied to the ETC fee deduction control equipment, and if the check is correct, first ciphertext information is extracted, converted into a PSAM card instruction and sent to PSAM read-write equipment;

the PSAM read-write equipment transmits an instruction to the PSAM card, the PSAM card carries out decryption operation, and the PSAM read-write equipment returns the result calculated by the PSAM card to the PSAM card access service equipment.

After receiving the PSAM card return information, the PSAM card access service equipment extracts the instruction reply content, namely decryption information, adds error correction information, and sends the information back to the ETC fee deduction control equipment.

The ETC fee deduction control device receives the decryption information returned by the PSAM card access service device, extracts the identification information in the decryption information, compares the identification information with the identification information obtained from the external service system, and only if the identification information is judged to be matched, the fee deduction request of the external service system can be processed in the next step.

The ETC fee deduction control system generates a fee deduction initialization instruction according to the read ETC card information and the identification information, sends the fee deduction initialization instruction to the ETC card read-write equipment, receives a processing result returned by the ETC card read-write equipment, and extracts information including the generated random number. And then combining the deduction amount, the identification information, the random number and the like into a deduction encryption request, adding error correction information into the remote network, sending the deduction encryption request to PSAM access service equipment, if an error or overtime error is returned, resending the deduction encryption request, and if the number of errors is too many, failing the whole deduction process, and returning the error to an external service system.

The PSAM card access service equipment checks the error correction information after receiving the fee deduction encryption request, if the check error exists, the check error is replied to the ETC fee deduction control equipment, if the check error exists, the fee deduction request information is extracted, converted into a PSAM card instruction and sent to PSAM read-write equipment;

the PSAM read-write equipment transmits an instruction to the PSAM card, the PSAM card carries out deduction encryption operation, and the PSAM read-write equipment returns a result (MAC1) calculated by the PSAM card to the PSAM card access service equipment.

After receiving the PSAM card return information, the PSAM card access service equipment extracts the instruction reply content, namely the fee deduction encryption information (MAC1), adds error correction information, and sends the information back to the ETC fee deduction control equipment, if an error or a timeout error is returned, the information is sent again, and if the number of errors is too many, the whole fee deduction process fails.

The ETC fee deduction control device receives fee deduction encryption information (MAC1) returned by the PSAM card access service device, integrates the fee deduction encryption information into a fee deduction instruction and sends the fee deduction instruction to the ETC read-write device.

The ETC read-write equipment sends the fee deduction instruction to the ETC card, the ETC card judges whether the instruction is legal or not according to the encrypted information in the fee deduction instruction, corresponding money amount is deducted from the ETC card according to a rule, and a fee deduction result identifier (MAC2) is generated after the deduction is successful and is returned to the ETC fee deduction control equipment.

The ETC fee deduction control device receives the fee deduction result identifier (MAC2), converts the fee deduction result identifier (MAC2) into a verification request, sends the verification request to the PSAM card access service device through a remote network, requests the PSAM card to verify, adds error correction information in the sending process, retransmits the request if an opposite side returns an error or an overtime error, fails the whole fee deduction process if the number of errors is too many, and returns an error to an external service system.

And the PSAM card access service equipment checks the error correction information after receiving the check request, if the check is wrong, the check error is replied to the ETC fee deduction control equipment, if the check is correct, the fee deduction result identifier (MAC2) is extracted, the fee deduction result identifier is converted into a PSAM card check instruction, and the PSAM card check instruction is sent to the PSAM read-write equipment.

The PSAM card read-write equipment transmits a verification instruction to the PSAM card, the PSAM card carries out verification operation, and the PSAM card read-write equipment returns an operation result to the PSAM card access service equipment.

After receiving the PSAM card return information, the PSAM card access service equipment extracts the instruction reply content, namely the verification result, adds error correction information, and sends the error correction information back to the ETC fee deduction control equipment.

And the ETC fee deduction control device checks the error correction information after receiving the verification result, if the error correction information and the verification result are both correct, the fee deduction request result of the external service system is correct, and if not, the fee deduction request result is wrong, and the fee deduction request result is returned to the external service system.

And the whole fee deduction process is finished.

The method is characterized in that:

the PSAM card may not be deployed on the site of the ETC fee deduction scene, but may be deployed in a different place of the ETC fee deduction scene, that is, deployed at will nationwide.

PSAM cards of different ETC fee deduction scenes can be arranged in a cluster in the same place in a centralized mode, and access efficiency can be greatly improved by means of cluster concurrency.

The PSAM card deployment site can manage a strict professional site, such as a machine room.

The ETC card read-write equipment and the PSAM card read-write equipment are remotely separated, and the ETC card read-write equipment and the PSAM card read-write equipment are in the same equipment or in the same local area network.

ETC fee deduction scene need not deposit or manage the PSAM card.

The interactive process between the PSAM card and the ETC card read-write equipment is carried out through a remote network, the process comprises decomposition and recombination of instructions, addition and verification of error correction information, sending, receiving, retransmitting and the like of information, and the whole process needs to be guaranteed to be within the specified time delay of an external service system.

The method of the invention has the advantages that:

the PSAM cards can be intensively deployed in a professional field instead of being deployed on the site of a fee deduction scene, so that the PSAM cards originally deployed in all parts of the country can be uniformly deployed in one place, strict management can be specially carried out, and the risk of losing the PSAM cards is avoided.

The unified PSAM access service equipment is adopted to carry out access management on the PSAM card, so that the risk of illegal use of the PSAM card is eliminated.

Adopt the PSAM card rather than adopting the mode of encryption machine to carry out the encryption and decryption operation to the ETC card, make this ETC system of withholding can support the ETC card of all parts of the country issuing, and the encryption machine of most high-speed management center all parts of the country all only has the key of this province, can only support the ETC card of this province issuing, can't accomplish the ETC card of supporting all parts of the country, consequently this scheme greatly increased the flexibility of service, and the market value of popularization.

The interaction process is as follows:

when the external service system sends a fee deduction request to the ETC fee deduction control device 1, the fee deduction request comprises identification information (such as a license plate or an ETC card number) of a fee deduction subject and the amount of fee deduction;

the ETC fee deduction control device 1 obtains the identification information, reads first ciphertext information of an OBU or an ETC card through an ETC card reading device, then sends the first ciphertext information to the PSAM card access service device 2 through a remote network, requests the PSAM card to decrypt, adds first error correction information in the sending process, resends the information if an error or overtime error is returned by the opposite side, fails the whole fee deduction process if the number of the errors is too many, and returns the error to an external service system.

The PSAM card access service equipment 2 checks the error correction information after receiving the decryption request, if the check is wrong, the first check failure information is replied to the ETC fee deduction control equipment 1, and if the check is correct, the first ciphertext information is extracted, converted into a PSAM card instruction and sent to PSAM read-write equipment;

the PSAM read-write equipment transmits an instruction to the PSAM card, the PSAM card carries out decryption operation, and the PSAM read-write equipment returns the result calculated by the PSAM card to the PSAM card access service equipment 2.

After receiving the information returned by the PSAM card, the PSAM card access service device 2 extracts the content returned by the instruction, that is, the decryption information, adds error correction information, and sends the information back to the ETC fee deduction control device 1.

The ETC fee deduction control device 1 receives the decryption information returned by the PSAM card access service device 2, extracts the identification information in the decryption information, compares the identification information with the identification information obtained from the external service system, and only if the identification information is judged to be matched with the identification information, the fee deduction request of the external service system can be processed in the next step.

The ETC fee deduction control system generates a fee deduction initialization instruction according to the read ETC card information and the identification information, sends the fee deduction initialization instruction to the ETC card read-write equipment 3, receives a processing result returned by the ETC card read-write equipment 3, and extracts information including the generated random number. And then combining the deduction amount, the identification information, the random number and the like into a deduction encryption request, adding error correction information into the remote network, sending the deduction encryption request to PSAM access service equipment, if an error or overtime error is returned, resending the deduction encryption request, and if the number of errors is too many, failing the whole deduction process, and returning the error to an external service system.

The PSAM card access service equipment 2 checks the error correction information after receiving the fee deduction encryption request, if the check error exists, the check error is replied to the ETC fee deduction control equipment 1, if the check error exists, the fee deduction request information is extracted, converted into a PSAM card instruction and sent to PSAM read-write equipment;

the PSAM read-write equipment transmits an instruction to the PSAM card, the PSAM card carries out deduction encryption operation, and the PSAM read-write equipment returns the result (MAC1) calculated by the PSAM card to the PSAM card access service equipment 2.

After receiving the PSAM card return information, the PSAM card access service device 2 extracts the instruction reply content, namely the fee deduction encryption information (MAC1), adds error correction information, sends the information back to the ETC fee deduction control device 1, and retransmits the information if an error or a timeout error is returned, and if the number of errors is too many, the whole fee deduction process fails.

The ETC fee deduction control device 1 receives fee deduction encryption information (MAC1) returned by the PSAM card access service device 2, integrates the fee deduction encryption information into a fee deduction instruction, and sends the fee deduction instruction to the ETC read-write device.

The ETC read-write equipment sends the fee deduction instruction to the ETC card, the ETC card judges whether the instruction is legal or not according to the encrypted information in the fee deduction instruction, corresponding money amount is deducted from the ETC card according to a rule, a fee deduction result identification (MAC2) is generated after the deduction is successful, and the fee deduction result identification is returned to the ETC fee deduction control equipment 1.

The ETC fee deduction control device 1 receives the fee deduction result identifier (MAC2), converts the fee deduction result identifier (MAC2) into a verification request, sends the verification request to the PSAM card access service device 2 through a remote network, requests the PSAM card to verify, adds error correction information in the sending process, retransmits the request if an opposite side returns an error or an overtime error, fails the whole fee deduction process if the number of errors is too many, and returns the error to an external service system.

The PSAM card access service equipment 2 checks the error correction information after receiving the check request, if the check is wrong, the check error is replied to the ETC fee deduction control equipment 1, if the check is correct, the fee deduction result identification (MAC2) is extracted, the identification is converted into a PSAM card check instruction, and the PSAM card check instruction is sent to PSAM read-write equipment.

The PSAM card read-write equipment 4 transmits a verification instruction to the PSAM card, the PSAM card carries out verification operation, and the PSAM card read-write equipment 4 returns an operation result to the PSAM card access service equipment 2.

After receiving the information returned by the PSAM card, the PSAM card access service device 2 extracts the reply content of the instruction, namely the verification result, adds error correction information, and sends the result back to the ETC fee deduction control device 1.

The ETC fee deduction control device 1 checks the error correction information after receiving the check result, if the error correction information and the check result are both correct, the fee deduction request result of the external service system is correct, otherwise, the fee deduction request result is wrong, and the fee deduction request result is returned to the external service system.
