Further specify technical scheme of the present invention below in conjunction with Figure of description and specific embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The dynamic token of being mentioned in the embodiment of the invention refers to the terminal that generates dynamic password, and said dynamic token includes but not limited to hardware token, note password and handset token.
With reference to Fig. 1, Fig. 1 is the dynamic token transaction confirmation method first embodiment schematic flow sheet of the present invention; As shown in Figure 1, dynamic token transaction confirmation method of the present invention may further comprise the steps:
Step S01, reception comprise character-coded challenge information;
Dynamic token can receive the character-coded information that has challenge that comprises of user's input through the input unit of self; In a preferred embodiment, said challenge information includes but not limited to the digital information of transaction number of the account, dealing money of user and so on.
Step S02, search according to the character code in the said challenge information and to preset the character library index, obtain the Word message that is associated with said challenge information;
When dynamic token receive through self input unit comprise character-coded challenge information after; Search according to the character code in the said challenge information and to preset the character library index; Obtain the word lattice information that said challenge information is associated, and send said Word message to relevant display module; Particularly, if the character code in the said challenge information is expressly, then searches and preset the character library index; If the character code in the said challenge information is a ciphertext, then said decrypt ciphertext is obtained corresponding plaintext after, according to said corresponding plaintext, search and preset the character library index.
In a preferred embodiment, said character code can also can be imported according to the form of ciphertext according to form input expressly.When said character code is imported according to the plaintext form, can directly search and preset the character library index according to the character code of said plaintext form; When said character code is imported according to the ciphertext form, obtain said character code corresponding plaintext according to presetting of the character code deciphering of deciphering rule earlier with said ciphertext form, search the said character library index that presets according to said character code corresponding plaintext again.
In a preferred embodiment; Said decrypting process can adopt dynamic token authentication server encryption/decryption algorithm of making an appointment and the key of making an appointment that said character code ciphertext is deciphered, and also can decipher calculating to the character code ciphertext according to generating the key of importing with challenge in the process of exchange at random.Said encryption/decryption algorithm is this area encryption/decryption algorithm commonly used; In a preferred embodiment; Said encryption/decryption algorithm can be SM3 algorithm, DES/3DES (Data Encryption Standard, data encryption standard) algorithm, HASH (Hash) algorithm etc.
Step S03, show said Word message, supply the user to confirm.
Relevant display module shows said Word message, and said Word message is offered user's affirmation.In a preferred embodiment, said Word message can be transaction number of the account holder's a literal title, like address name or Business Name etc., or other Word messages relevant with transaction, so that the user confirms Transaction Information.
Present embodiment dynamic token transaction confirmation method comprises character-coded challenge information, searches according to the character code in the said challenge information and preset the character library index through reception; Obtain the Word message that is associated with said challenge information; Said Word message is transmitted and is shown to the user; The method that supplies the user to confirm has realized when the user carries out the dynamic token transaction beneficial effect to succinct validation of information.
With reference to Fig. 2, Fig. 2 is the dynamic token transaction confirmation method second embodiment schematic flow sheet of the present invention; As shown in Figure 2, dynamic token transaction confirmation method of the present invention also comprises step before in the step that step S01, reception comprise character-coded challenge information:
