Embodiment
For ease of the understanding to the embodiment of the present invention, be further explained explanation below in conjunction with accompanying drawing for several specific embodiment, and each embodiment does not form the restriction to the embodiment of the present invention.
Embodiment one
The handling process schematic diagram of the acquisition methods of the transaction key of a kind of safety card that this embodiment provides as shown in Figure 1, comprises following treatment step:
First step 11, safe card generate the public private key pair of user, the PKCS#10(Public-KeyCryptographyStandards carrying the information such as essential information, client public key of above-mentioned user is sent to financial platform, the public key cryptography standard of certificate request) request, above-mentioned user is the user of above-mentioned safe card.
After step 12, financial platform receive above-mentioned PKCS#10 request, to financial CA(certificateauthority, authentication center) send and carry the essential information of above-mentioned user, the user certificate application request of client public key.
After step 13, financial CA receive above-mentioned user certificate application request, generate the user certificate of above-mentioned user, this user certificate comprises the information such as essential information of CertPubKey, the term of validity, issuing organization, user, and the concrete numerical value of above-mentioned CertPubKey is equal with the concrete numerical value of above-mentioned client public key.
Above-mentioned user certificate is sent to above-mentioned financial platform by step 14, financial CA.
After step 15, financial platform receive above-mentioned user certificate, above-mentioned user certificate is stored in the memory of inside.Then, extract the information such as the CertPubKey in user certificate, the term of validity, issuing organization, send the transaction key application request of essential information of carrying CertPubKey, user to financial encryption equipment.
After step 16, financial encryption equipment receive above-mentioned transaction key application request, generate the transaction key information of above-mentioned user according to the algorithm of setting, and use CertPubKey to be encrypted transaction key information.
In actual applications, above-mentioned transaction key information can be the index that multiple transaction key and each transaction key are corresponding.Transaction key information after above-mentioned encryption stores by finance encryption equipment in the memory of inside.
Step 17, financial encryption equipment return to financial platform the transaction key information after encryption, and the transaction key information after the encryption received stores by financial platform in the memory of inside.Then, the transaction key information after above-mentioned encryption is returned to safe card.
After step 18, safe card receive the transaction key information after above-mentioned encryption, the transaction key information after using private key for user to decipher above-mentioned encryption, the correctness of checking unsymmetrical key.In deciphering with after being proved to be successful, the transaction key information after above-mentioned encryption is stored in the memory in inner place of safety by safe card.
Embodiment two
The handling process schematic diagram of the using method of the transaction key of a kind of safety card that this embodiment provides as shown in Figure 2, comprises following treatment step:
Step 21, safe card extract the transaction key information ciphertext after public key encryption from place of safety, and the transaction key ciphertext after safe card uses private key for user deciphering public key encryption obtains transaction key information.When above-mentioned transaction key information is index corresponding to multiple transaction key and each transaction key, safe card chooses a transaction key that will use from above-mentioned multiple transaction key, obtains the index of this transaction key.
Step 22, safe card use the transaction key chosen expressly to carry out 3DES-ECB(TripleDataEncryptionAlgorithm, triple DEA-electronics treasured private copy of a rare book mode to trading password) encryption, obtain the trading password ciphertext after encrypting.
Step 23, safe card use UTF-8(8-bitUnicodeTransformationFormat, 8 bit Unicode format transformations) coded system obtains the MD5 digest of transaction request message, again cover process is carried out to above-mentioned MD5 digest, at last benefit 8 byte values of MD5 digest, these 8 byte values are: ' 0x8000000000000000 '.
The MD5 digest of safe card to above-mentioned cover carries out MAC(MessageAuthenticationCodes, the hashing algorithm of message) calculate, MAC calculates the 3DES-CBC(TripleDataEncryptionAlgorithm of employing standard, triple DEA-cipher block chaining mode) algorithm, 8 bytes of last DES computing are exported leftmost 4 byte datas of data as MAC effect value.
Step 24, safe card to financial platform send comprise above-mentioned trading password ciphertext, use the financial transaction request of the information such as index, MAC effect value of transaction key.
After step 25, above-mentioned financial platform receive above-mentioned financial transaction request, the index of above-mentioned used transaction key, MAC effect value are sent to financial encryption equipment, finance encryption equipment is verified the index of above-mentioned used transaction key, MAC effect value, after being verified, return the information of being verified to financial platform, financial platform carries out follow-up process to above-mentioned financial transaction request.
Finance encryption equipment does not return authentication failed information by rear to financial platform in above-mentioned checking, and financial platform returns transaction-declined message to above-mentioned safety card sheet.
