Safe and intelligent POS and method for secure transactions that safety chip is stored to transaction identity information and public private key data.
Background technology
POS generally makes as a kind of easily Cash collecting equipment in places such as market, shops, enterprises and institutions, companies
With.Conventional POS generally only has function of swiping card, and magnetic stripe card or IC-card can be identified, but with mobile payment（It is micro-
Letter, Alipay）Develop rapidly and popularize, existing POS integrate swipe the card, scan, near-field communication pay, it uses number
According to the more powerful Andiord systems of disposal ability.Andiord systems for its bring it is multi-functional simultaneously, there is also safety
Hidden danger.Because Andiord systems are more intelligent, this also causes its Transaction Information and data to be easier to be stolen so that POS exists
Certain security risk is there is during financial transaction.
The content of the invention
There is provided a kind of safe and intelligent POS and Secure Transaction side in order to overcome the shortcoming of above-mentioned technical problem by the present invention
Method.
The safe and intelligent POS of the present invention, including CPU and coupled magnetic head, camera, input button, display
Screen, Printer drive module and common storage, CPU are used to setting up and running normal operating system and security isolation operation system
System；CPU carries out payment of swiping the card by magnetic head, and barcode scanning payment is carried out by camera；Input button be used for input control instruction and
Trading password, display screen is used to show Transaction Information, and Printer drive module is used to print transaction voucher；It is characterized in that：Institute
State CPU and be connected with safety chip, safety chip is by encrypting module and coupled interface module and secure storage module group
Into secure storage module is used to store identity information and public private key data, and the encryption and decryption that encryption/decryption module is used for public private key pair is grasped
Make；Encryption/decryption module is communicated by interface module with CPU, so that CPU is obtained in secure storage module by encryption/decryption module
The identity information of storage and public private key data.
The safe and intelligent POS of the present invention, the CPU is connected with NFC communication modules and bluetooth communication module, and CPU passes through
NFC communication modules carry out near-field communication transaction, are communicated by bluetooth communication module with smart machine.
The safe and intelligent POS of the present invention, the encryption/decryption module is made up of arithmetic element circuit, the safety storage mould
Block is made up of memory cell.
The safe and intelligent POS of the present invention, the CPU is communicated through bus with safety chip.
The digital certificate method of commerce of the safe and intelligent POS of the present invention, it is characterised in that by following steps come real
It is existing：
Step 1：Request is initiated, user is by running on the client software in safe and intelligent POS to business processing backstage system
System initiates transaction request；Business processing background system is run on the server of service organization；Step 2：Return at response, business
Manage background system and return to response message to client software；Rapid 3：Transaction Information is inputted, client software is received after response message,
The Transaction Information interface that prompting user is inputted including the account title of both parties, account number is produced, user's input is handed over
After easy information and confirmed；Step 4：Transaction Information is submitted, Transaction Information is sent to security isolation and operated by client software
Environmental system, and carry out credible interactive interface echo；Security isolation operating environment system be and safe and intelligent POS its own system
The autonomous system of paired running；Step 5：Information is echoed, and security isolation operating environment system is shown by credible interactive interface and handed over
Easy information, so that user is traded validation of information, anti-information, which is write, to be changed；Security isolation operating environment system is from safety chip
Data are obtained, the authentication data including trading signature, public key certificate are returned to client software；Step 6：Electronic signature,
After the Transaction Information that credible interactive interface is shown confirms, the Transaction Information including account title, account number is submitted to safety
Signature is traded in chip, safety chip carries out signature processing using the private key of storage；Step 7：Return to signing messages and card
Book, safety chip returns to signed data and certificate gives business processing background system；Step 8：Send after sign test request, business processing
Signed data and authentication data are sent to signature sign test system by platform system, carry out sign test request；Sign sign test system operation in
On the server of service organization；Step 9：Merchandise sign test and returning result, signature sign test system according to the signed data of reception and
Authentication data carries out sign test to transaction, judges whether it is legal, and transaction sign test result is back into business processing background system；
Step 10：Trading processing result is returned to, business processing background system completes trading processing, and return according to signature verification result
Transaction results are to client software；Step 11：Transaction results are shown to user by client software, complete transaction.
The beneficial effects of the invention are as follows：The safe and intelligent POS of the present invention, CPU is led to by connecting magnetic head, camera, NFC
Module is interrogated, payment of swiping the card, barcode scanning is realized and pays and near-field communication payment so that POS integrates a variety of payment functions, full
The foot demand of existing a variety of means of payment.CPU is made up of by connecting encryption/decryption module, interface module and secure storage module
Secure storage module, secure storage module realizes the storage to identity information, public and private key, and encryption/decryption module is used to perform public affairs
The encryption and decryption operation of private key pair.The security isolation operating system of only CPU operations can just pass through the encryption and decryption mould in safety chip
The identity information and public private key data stored in block access secure storage module, and the normal operating system run is without permission,
It can not access, it is ensured that use the safety of POS process of exchange.The method of commerce of the present invention, using safety in process of exchange
Isolated operation environment confirms to Transaction Information, and the private key stored in safety chip calculates number of signature to transaction data
According to, and signed data, public key certificate, Transaction Information etc. are returned into service organization are together traded checking, complete transaction.
The safe and intelligent POS and method for secure transactions of the present invention, due to being provided with the safety chip being connected with CPU,
Safeguard protection than soft encryption higher level safe class can be provided, realize from bottom and solve safe and intelligent POS
