The invention provides a wallet encryption storage method, a signature method, computer equipment and a storage medium, and the method comprises the steps: a wallet application obtains a user key in response to an account creation instruction, and sends the user key and the account creation instruction to a first TA in a TEE; the first TA responds to the account creation command, generates a first private key, and a first public key, a first address and a first mnemonic word corresponding to the first private key, and returns the first public key and the first address to the wallet application; the first TA generates a trusted storage key according to the user key and the HUK of the computer equipment; the first TA generates a file encryption key, encrypts the first private key and the first mnemonic word according to the file encryption key, and generates and stores encrypted private key information; and the first TA encrypts the file encryption key according to the trusted storage key, and generates and stores encryption key information. According to the invention, asset loss caused by stealing of wallet data is avoided.
Description
technical field [0001] The present application relates to the technical field of the Internet, in particular to a wallet encryption storage method, signature method, computer equipment and storage medium. Background technique [0002] Current blockchain wallets store sensitive data such as private keys or mnemonic words by encrypting these sensitive data with the user key and storing them on the hard disk. [0003] The problem with the above solution is that when the computer equipment storing the encrypted sensitive data is hacked, the intruder can steal the encrypted sensitive data, and then steal / defraud the user key, crack the user key according to the user’s private information, etc. The stolen data is decrypted, resulting in the risk of sensitive data such as private keys or mnemonics being stolen and cracked, resulting in asset loss. Contents of the invention [0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide ...
