A self-destructing hardware wallet

Abstract

The invention discloses a self-destruction hardware wallet, which includes a power supply module, a control module, a safety monitoring module, a storage module, a safety module, an application module, and a communication module. The storage module, the safety module, the application module, and the communication module are respectively connected with The control module is connected to realize the function of the hardware wallet; the security monitoring module is used to monitor various types of attacks, and the monitored signal is transmitted to the control module, and the control module is used to judge whether the hardware wallet is based on the signal detected by the security monitoring module. Under attack, use the ram with uninterrupted power supply as the memory. If it is confirmed that the hardware wallet is under attack, the control module is used to control the memory power-off control module to disconnect the power supply of the ram, control the power-off of the ram, and automatically erase the memory in the ram. Key information, account information. 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 self-destruction hardware wallet. 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 the private key in the networ...

AI Technical Summary

Problems solved by technology

Hardware wallets generally use ram as a container for storing private keys, and there is a risk that the private key may be obtained by disassembling the phone and directly reading the contents of the memory, 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.
