Abstract

The invention discloses a hardware wallet off-line upgrading device of based on an Ubuntu system, which incluses: server side, a hot end, and a cold end; the server end stores an upgrade package fileand a first private key for encrypting the upgrade package file, the hot end is a movable terminal device with a display function, and the hot end is provided with a data interface module and a data dividing module. the cold end including a first public key and a second private key is provided with a collection module, an analysis module and a data merging module. The invention also discloses an offline upgrading method of a hardware wallet, the method adopts the scanning and parsing of the two-dimensional code to transmit the encrypted upgrade package file of the hardware wallet, the fact that hardware wallet and the insertion action of the computer or the mobile terminal can cause the hardware wallet to be infected with the Trojan horse or the virus on the computer or the mobile terminalcan be avoided. The offline upgrading method avoids the possibility of hacking the hardware wallet, thereby strengthening the security protection level of the hardware wallet.

Description

technical field [0001] The invention relates to the field of digital assets, in particular to an Ubuntu system-based hardware wallet offline upgrade device and method. Background technique [0002] A hardware wallet refers to storing the private key of a digital asset separately in a chip, isolated from the Internet, and plug-and-play. When the hardware wallet needs to store new digital assets, the support of the new token wallet must be updated, and the system upgrade of the hardware wallet is required. The existing offline upgrade method is to insert the hardware wallet into the computer or mobile terminal that has downloaded the upgrade package file, and the hardware wallet can complete the system upgrade. In this way of implementation, since the hardware wallet is inserted into the computer or mobile terminal, the hardware wallet will be infected with Trojan horses or viruses on the computer or mobile terminal. This offline upgrade method will bring hidden dangers to th...
