Transaction information verification method and device

Abstract

The invention provides a transaction information verification method and a transaction information verification device. The transaction information verification method comprises the following steps: receiving transaction information submitted by a user, and performing digital signature and encryption processing; transmitting encryption transaction information with a digital signature to an electronic bank server, verifying the digital signature and judging the legality of the transaction information through the electronic bank server, and after judging that the digital signature is qualified and the transaction information is legal, generating a transaction verification code according to the transaction information; receiving a transaction verification code and a server electronic signature fed back from the electronic bank server, and verifying the server electronic signature; after the verification is approved, prompting the user to input the verification code in a mode that button lamps are lightened or tuned off or the colors of the button lamps are changed through corresponding buttons according to the transaction verification code; judging whether the verification code input by the user through operation buttons is correct or not; after the verification code is correctly input, generating verification approval information, transmitting to the electronic bank server, and processing the transaction information through the electronic bank server according to the verification approval information, and completing the transaction.

Description

technical field [0001] The invention relates to the technical field of information encryption, in particular to a transaction information verification method and device. Background technique [0002] Nowadays, e-banks generally use information encryption devices such as USBKeys to authenticate customers, through information encryption devices without buttons (such as: a generation of USBKeys without buttons on the surface), or information encryption devices that require users to press buttons to confirm transactions (such as : The second-generation USBKey with confirmation, cancellation and page-turning buttons) is set to ensure the confidentiality and safety of electronic banking financial transactions. However, with the development of computer technology, the trading environment varies greatly. When the trading terminal is attacked by a malicious program, the general information encryption device has the following problems: [0003] 1. The problem of transaction tampering...
