Embodiment
Below, with reference to accompanying drawing and embodiment, the present invention is described further, it is necessary to which explanation is, not
Under the premise of afoul, new implementation can be formed between various embodiments described below or between each technical characteristic in any combination
Example.
A kind of PSAM arrays cryptographic calculation method of servicing, as shown in figure 1, comprising the following steps：
In one embodiment, step is also included before step receives request and sends request, charging terminal reads ETC cards
After card data, charging terminal sends PSAM cryptographic calculations service request to backstage of charging online.
Request is received, the main thread on backstage of charging receives PSAM cryptographic calculation service requests, and distributes sub-line journey processing
PSAM cryptographic calculation service requests.
Verification request, sub-line journey verify to the legitimacy of PSAM cryptographic calculation service requests, obtain check results；It is excellent
Selection of land, step verification request include verifying the username and password of charging terminal, and the sequence number and verification for verifying charging terminal are received
Take the encrypted ones of terminal, the encrypted ones for verifying charging terminal are that decryption is encrypted to the character string of charging terminal upload to test
Card.
Dynamic call resource, when check results pass through for verification, it is preferable that it is initial that step dynamic call resource includes equipment
Change, charge backstage initializes to PSAM cards and card reader, and card reader is for reading the data of PSAM cards, and sub-line journey is to charge
PSAM resources are distributed in background request PSAM resources, charge backstage to sub-line journey, and sub-line journey calls the processing PSAM encryptions of PSAM resources
Computational service is asked, it is preferable that charge is from the background idle condition to the state that sub-line journey distribution PSAM resources are specially card reader
When, charge backstage distributes card reader to sub-line journey and PSAM cards handle PSAM cryptographic calculation service requests, it is preferable that card reader
State includes idle condition, lock-out state, bad down state, and idle condition represents that card reader is unoccupied, lock-out state
Represent that card reader is currently being used, bad down state expression card reader has been gone bad unavailable, in one embodiment, such as Fig. 2 institutes
Show, mobile phone rate terminal is charging terminal, it is preferable that PSAM cryptographic calculations service request includes data encryption request, calculating disappears
Take key request, verification consumption check code asks the request of sum check flowing water check code, it is preferable that PSAM cryptographic calculation service requests
For online PSAM cryptographic calculations service request, charging terminal sends data encryption request, and data encryption request is request PSAM cards
The random number that ETC cards are sent is encrypted, sub-line journey calls PSAM resources that data are encrypted, and it is close that charging terminal sends calculating consumption
Key is asked, and is calculated consumption key request and is calculated consumption key MAC1 for request PSAM calorimeters, charge backstage sends MAC1 to charge
Terminal, charging terminal are obtained by MAC1 and write card authority, write data in card, while generate consumption check code MAC2 and flowing water school
A yard TAC is tested, sub-line journey calls PSAM Resource Calculations consumption key, and charging terminal sends verification consumption check code MAC2 requests, son
Thread dispatching PSAM resource checksums consume check code MAC2, and charging terminal sends the TAC requests of verification flowing water check code, and sub-line journey is adjusted

ETC cards carry out writing operation, and MAC2 is used to verify the card true and false, reduces pseudo- card transaction risk, it is true that TAC is used for checkout transaction flowing water
Puppet, prevent from forging transaction journal.
In one embodiment, when card reader resource is all occupied, i.e., when Card reader status does not have idle condition, wait to locate
The request of reason is stored in a manner of queue, i.e., sub-line journey is stored with queue, waits card reader resource to be released, as system includes reading
Card device A, PSAM card 1, card reader B, PSAM card 2, card C to be consumed, card D to be consumed and card E to be consumed, card reader A are read
The data of PSAM cards 1 are taken, card reader B reads the data of PSAM cards 2, when card C and card D asks card reader resource simultaneously,
System is randomly assigned the card reader processing card C and card D of free time request, such as card reader A processing cards C request, Card Reader
Device B processing cards D request, after card reader is occupied, Card reader status is lock-out state during consumption, if now card E
Card reader resource is asked, then the sub-line journey for handling card E requests enters enqueue, when card reader A or card reader B state are the free time
During state, card reader resource response is triggered, queue is according to the principle of first in first out, the sub-line journey taking-up that processing card E is asked,
The card reader processing card E of idle condition request, because the time of card reader locking state is that the time that card is consumed is extremely short, is used
Not waited on the sense organ of family too long, it is contemplated that concurrency is very big under actual conditions, and actual card lock dead time can not reduce,
Therefore PSAM arrays are established, i.e., uses a PSAM card using substantial amounts of card reader, each card reader so that a card reader energy
Enough consumer requests for tackling 10 cards " simultaneously ".
In one embodiment, it is preferable that also asked including step record, the record PSAM cryptographic calculation requests of charge backstage,
Request record is obtained, request record is used to inquire about PSAM cryptographic calculation service requests, lifting management convenience, convenient processing dispute
Complain.
