A new type of hardware wallet with dismantling and self-destruction

Abstract

The invention discloses a new hardware wallet with self-destruction after dismantling, including a power supply module, a control module, a safety monitoring module, a memory safety protection module, a storage module, a safety module, an application module, and a communication module. The hardware wallet supplies power, and the storage module, security module, application module, and communication module are respectively connected to the control module to realize the function of the hardware wallet; the security monitoring module is used to monitor various types of attacks and transmit the detected signals to the control module , the control module is used to judge whether the hardware wallet is under attack according to the signal detected by the security monitoring module. Clear the area in which key information and account information are saved. It improves the security and reliability of existing hardware wallets.

Description

technical field [0001] The invention relates to the field of digital currency, in particular to a novel hardware wallet with self-destruction when disassembled. Background technique [0002] Digital currency is an electronic form of alternative currency, such as the popular Bitcoin, Litecoin and PPCoin. These digital currencies rely on cryptography and verification technology. Each currency holder needs to keep at least one pair of private key and public key, which is the proof of personal digital assets. Mastering the private key is equivalent to mastering a person's bank account. Once the private key is stolen, all the property corresponding to the private key will be lost. In the field of digital currency, the importance of private keys is self-evident. [0003] The hardware wallet is a container for storing the private key. The private key is stored locally and the signature generated by the private key is provided externally, thus effectively avoiding the exposure of ...

AI Technical Summary

Problems solved by technology

Hardware wallets generally use flash as a container for storing private keys. There is a risk that the private key may be obtained by disassembling the phone and directly reading the contents of the storage, that is, the private key is stolen from the local

In addition, in the face of special changes in the external environment, such as changes in voltage, temperature, frequency, etc., hardware wallets may be disturbed or memory tampered, causing security issues

At present, the common hardware wallets on the market include: Ledger, Trezor, keepKey, Kushen, etc. These hardware wallets do not have anti-demolition and self-destruction functions, and cannot prevent the private key in the hardware wallet from being stolen locally.
