Abstract

The invention aims to provide a method and equipment for secure offline electronic payment of a token model payment object. The method comprises the following steps: determining first information based on configuration information of payee equipment; enabling the payer equipment to select a paid object meeting a condition from existing paid objects, and determining second ciphertext information according to the information of the selected paid object and the first information; enabling the payee device to decrypt the second ciphertext information, verify a plurality of target items generated by the payer device for the payment according to a result obtained by decryption of the second ciphertext information, and obtain a verification result; and determining third information according to the verification result, and sending the third information to the payer device. Therefore, the payment object can be safely processed under the offline transaction, and particularly, the double-spam attack is avoided.

Description

technical field [0001] The present application relates to the computer field, and in particular to a method and device for secure off-line electronic payment of token model payment objects.
