Abstract

The invention discloses a timestamp-based transaction verification method. The method comprises the steps that a system is initialized, an issuer acquires a system clock from an operator to complete time synchronization, the operator generates an operator timestamp main key, and the issuer generates an issuer timestamp main key; operator timestamp sub-keys obtained after dispersion of the operator timestamp main key are released to the issuer, and a user acquires the operator timestamp sub-keys from the issuer and issuer timestamp sub-keys obtained after dispersion of the issuer timestamp main key; in the transaction process, the user performs operation to complete an order and submits the order to the operator, the order is dually encrypted with the operator timestamp sub-keys and the account issuer timestamp sub-keys; the operator verifies the order through the operator timestamp main key, and the order is submitted to the issuer after passing the verification; and the issuer verifies the order through an issuer timestamp, and payment is completed if the order passes the verification. Through the method, dual verification can be realized, and therefore the security and validity of payment verification are further improved.

Description

technical field

[0001] The invention relates to the technical field of transaction verification, in particular to a transaction verification method based on time stamps. Background technique

[0002] With the development of mobile payment methods, higher requirements are put forward for payment verification. Payment verification requires safety and effectiveness. At present, most of the verification methods use the unilateral verification method of the operator, lacking the verification of the issuer, and the operator's falsified transaction will cause the issuer to suffer losses. Contents of the invention

[0003] Aiming at the above problems, the present invention proposes a transaction verification method based on time stamps, which adopts a dual time stamp mechanism, wherein one time stamp key is controlled by the terminal operator to prevent copying and retransmission, and the other is controlled by the account issuer , used to prevent the terminal operator from forg...
