Embodiment

[0055] The POS digital signature anti-cutting machine system described in this embodiment, the system includes: a client, a server and a POS operating system, and the client is connected to the server by communication;

[0056] The client is responsible for sending the program software code and the code executable file to the server, the server backs up the code, signs the code executable file, and after obtaining the signed data, publishes the program software to the POS machine operating system Issue;

[0057] The server end is responsible for signing the data sent by the client, and returning the signed data to the client;

[0058] When the POS machine running system obtains a new version of the installed software, it requests to download and install and run the new version of the software, and uses the public key stored in the POS machine running system to verify the signature during the process of downloading, installing and running the new version of the software.

Abstract

The invention discloses a POS digital signature anti-switching machine system and relates to the field of program devices. The system comprises a client, a server and a POS machine operation system, wherein the client is in communication connection with the server and is used for sending a program software code and a code executable file to the server, the server backs up the code and signs the code executable file, and after signed data is obtained, a release version of program software is published to the POS machine operation system; the server is used for signing data sent by the client and returning the signed data to the client; the POS machine operation system is used for requesting downloading, installing and running of new-version software when new version of obtained and installed software is released, and a public key stored in the POS machine operation system is used for verifying signature during downloading, installing and running of the new-version software. With adoption of the system, signed programs of different clients cannot be downloaded or run, and brute force attack and illegal use by users are prevented.

Description

technical field [0001] The invention relates to the field of program devices, in particular to a POS digital signature anti-cutting machine system. Background technique [0002] At present, POS machines are widely popularized and used in various industries. The bank card acquiring business, as the acquiring link of the bank card system operation, is also the most important part of the bank card acceptance environment. With the development of bank card business in recent years, especially at the end of 2011, the People's Bank of China released restrictions on bank card acquisition and began to issue third-party payment licenses, and the acquiring market has been greatly developed. The volume of POS distribution has repeatedly hit new highs. [0003] However, while the acquiring market is booming, extensive development methods and disorderly competition have also caused many problems and financial risks. Among them, POS agents switch POS programs by themselves, which is one ...
