Problems solved by technology

[0004] The disadvantages of this existing method are: 1) completely rely on the CA center to generate an asymmetric key pair, which increases the operating load of the CA center server, does not make full use of the performance of the POS terminal, and cannot be flexibly based on the performance of the POS terminal itself. reasonable load balancing
2) When the asymmetric key pair is generated by the server of the CA center and then sent back to the POS terminal, there is a security risk of the private key in the data transmission process, and it is necessary to design a complete set of schemes for the secure transmission of private keys for sensitive information data

Embodiment 1

[0077] The performance of the POS machine can be high or low. The high-performance POS machine can quickly and autonomously generate an asymmetric key pair, and store the private key in the POS terminal in a safe manner. Only the public key and the matching public key in the asymmetric key pair Other certificate configuration information can be passed to the CA center to apply for a CA certificate; however, low-performance POS machines have low efficiency in generating key pairs. It is not feasible to rely on POS terminals to generate asymmetric key pairs independently, and must rely on the server of the CA center To generate an asymmetric key pair, and at the same time generate a CA certificate, the CA center sends the certificate and private key (in a secure transmission of sensitive data) back to the POS.

[0078] Please refer to figure 2 This embodiment provides a configurable method for generating key pairs for POS terminals, which can make full use of the performance of PO...

Embodiment 2

[0095] This embodiment corresponds to the configurable POS machine key pair generation method of the first embodiment, and provides a computer-readable storage medium on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0096] A preset configuration file, the parameters in the configuration file include a terminal key pair generation method, the terminal key pair generation method includes a key pair generated by the terminal independently or a key pair generated by the CA center; preferably, it can be set The first parameter corresponds to the key pair generated by the terminal independently, and the second parameter corresponds to the key pair generated by the CA center. Preferably, the configuration file is in a readable ini file format or an xml file format, and the parameters therein further include the name of the configuration file, the path name stored in the terminal, the version number and the gene...

Abstract

The present invention provides a configurable POS machine key pair generation method and a computer-readable storage medium. The method includes: a preset configuration file, the parameters in the configuration file include a terminal key pair generation method; according to the produced terminal For its own performance, set the parameter of the terminal key pair generation method in the corresponding configuration file; during the production process, the terminal obtains the corresponding configuration file; the terminal parses the configuration file, and according to the terminal key pair set in the configuration file The key pair generation method generates a key pair. The present invention can not only make full use of the performance of the POS machine terminal, reduce the load of the server of the CA center; but also reduce the number of transmissions of sensitive data and improve data security; Consistency, no need to design different equipment production processes for different asymmetric key pair generation schemes, and at the same time meet various needs.

Description

Technical field [0001] The invention relates to the field of electronic payment, in particular to a configurable POS machine key pair generation method and a computer-readable storage medium. Background technique [0002] POS (point of sale) is a multi-functional terminal. It can be installed in the designated merchants and acceptance outlets of credit cards to connect to the computer to form a network to realize automatic transfer of electronic funds. It has support for consumption, pre-authorization, balance inquiry and Functions such as transfers. Since the data interaction and transmission process between the POS machine and the merchant's back-end is carried out in an open environment, in order to ensure the safety and reliability of the POS use process, to prevent someone from maliciously monitoring network data and obtaining cardholder information and corresponding information Password, the information interaction between the POS machine and the merchant's back-end server...
