Abstract

The invention relates to a system and method for validating the chip validity by utilizing a graphical chip. The system comprises an identifier generation module, a graphical identifier identification module and an identifier validation module. The method for validating the chip validity comprises three basic work flows, namely a graphical identifier generation flow, a graphical identifier identification flow and a graphical identifier validation flow. When validating the chip validity, a user uses the graphical identifier on an identification chip of the graphical identifier identification module, and the graphical identifier is reduced into a verification identifier, the verification identifier is transmitted to the identifier validation module, the identifier validation module compares the verification identifier with an internal identifier which is saved in a chip, the graphical identifier of the chip is falsified if the validation identifier is not in accordance with the internal identifier, and the user can determine whether the chip is counterfeited or illegal or not and further forbids the user to download an application program; and the chip is legal if the validation identifier is in accordance with the internal identifier.

Description

technical field

[0001] The invention relates to the field of information security, in particular to a system and method for verifying the legitimacy of chips. Background technique

[0002] With the development of information security technology, various security products are becoming more and more popular, including USBKEY for online banking, TF-SIM card for mobile payment, trusted computing TCM chip, encrypted U disk, etc. These security products use security chip to implement its security functions. Due to the broad market prospects and huge profit margins of security chips, illegal operators will try to tamper with chips produced by well-known manufacturers by tampering with their own chips, or forge famous manufacturers on the surface of chips produced by non-known manufacturers. identification, from which illegal benefits are obtained. In addition, in order to ensure the security of chip use, users who do not have the right to use the chip and malicious attackers shou...
