Abstract

The invention discloses a method for enhancing information security of a POS terminal. A system program is installed in the POS terminal, which includes the following steps: a blacklist program is pre-installed in the POS terminal, and the blacklist program contains published But there is a file with BUG; the system program detects in real time whether the file to be downloaded has been blacklisted, and if so, refuses to download; if the file to be downloaded is not blacklisted, then the system to be downloaded The file is signed and authenticated to determine whether the signature is legal, if not, then refuse to download, and if so, allow the download. The present invention pre-embeds a blacklist program that can be updated remotely and in time in the POS terminal, which can avoid downloading published files with bugs, improves the information security of the POS terminal, and minimizes the risk of information leakage and personal property loss .

Description

technical field [0001] The invention relates to the field of information security of financial POS terminals, in particular to a method for enhancing information security of POS terminals. Background technique [0002] POS terminals involve the processing of important information such as personal account numbers, PINs, and amounts, so they have very high requirements for the security of data information. [0003] Existing solutions usually use signature authentication to ensure that the loaded and running programs are legally authorized, and use encryption to prevent the key data of the communication link from being leaked. [0004] However, for programs or files that have been released and have vulnerabilities, the existing solutions can only remedy the vulnerabilities through manual or remote upgrades, which requires a comprehensive assessment of labor costs, network environment and load, and terminal performance. [0005] Therefore, the prior art still needs to be improv...
