Problems solved by technology

[0009] 1) The performance of the POS terminal security chip is insufficient, and it takes time to generate a key pair. For example, generating a pair of RSA2048 keys takes tens of seconds
[0010] 2) When the POS terminal requests CA / RA to issue a certificate, there is a security risk in the communication because there is no relevant key and certificate without the help of manual and other trusted devices.

Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be further described below.

[0036] Such as figure 1 As shown, the present invention proposes a method for intelligent POS device certificate loading, comprising the following steps:

[0037] 1. The process of issuing certificates in batches:

[0038] 1) The terminal certificate management server TCMS pre-generates a batch of public-private key pairs. This operation is completed by the hardware encryption machine HSM according to the set algorithm type and algorithm strength, and the private key is safely stored in the HSM;

[0039] 2) The TCMS server generates a certificate request CSR for each public-private key pair;

[0040] 3) TCMS and CA / RA server perform bidirectional verification, and submit the certificate request CSR to CA / RA to issue a device public key certificate after passing the authentication;

[0041]...

Abstract

The invention provides an intelligent POS equipment certificate loading method, which mainly realizes certificate batch signing and issuing and certificate loading through a CA / RA server, a certificate management server TCMS, a security key device SCD and a POS, so as to provide an intelligent POS equipment certificate loading method for safely and quickly loading POS terminal equipment certificates.

Description

technical field [0001] The invention relates to the technical field of POS terminals, in particular to a method for loading a smart POS device certificate. Background technique [0002] Each POS terminal needs to load its identity certificate before leaving the factory, which is used to establish CA certificate-based communication with the remote server. [0003] In the existing technical solution, the process of loading the POS identity certificate is roughly as follows: [0004] 1) The POS terminal generates a key pair and generates a certificate request CSR. [0005] 2) The POS terminal establishes a network connection with the CA / RA, and sends the certificate request CSR to the CA. [0006] 3) The CA checks the relevant information, issues a certificate, and sends it to the POS terminal. [0007] 4) The POS terminal receives the certificate and loads it. [0008] This process has the following problems: [0009] 1) The performance of the security chip of the POS ter...
