Abstract

The invention relates to an offline key transmission method and device. The method comprises the following steps: establishing a serial port communication connection with a sales terminal used for downloading a key through a data communication port; receiving a transmission key sent by the sales terminal used for downloading the key through the serial port communication; encrypting a to-be-downloaded key through the transmission key; sending the encrypted to-be-downloaded key to the sales terminal used for downloading the key; receiving an acknowledgement message fed back by the sales terminal used for downloading the key; and disconnecting the serial port communication connection with the sales terminal used for downloading the key according to the acknowledgement message. By adoption of the offline key transmission method and device provided by the invention, key transmission in an offline state is realized, and the key transmission security is high.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a key off-line transmission method and device. Background technique [0002] With the rapid development of mobile payment technology, the sales terminal (POS terminal Point of sales terminal), as the front-end hardware device of the financial payment system, has also undergone rapid development, and POS terminals using various new technologies have emerged rapidly, such as Bluetooth POS terminals , smart POS terminals and cloud POS terminals, etc. POS terminals need to encrypt transaction sensitive information because it involves personal account and property security. However, the sales terminal used to download the key is limited by the network environment. When it can only access the transaction network and cannot access other networks, it cannot perform key transmission with the sales terminal used to provide the key. Contents of the invention [0003] Based on ...
