The present invention provides a wallet encryption storage method, a signature method, a computer device and a storage medium. The method includes: a wallet application, in response to an account creation instruction, obtains a user key, and sends the user key and account creation to a first TA in the TEE command; the first TA generates a first private key in response to the account creation command, and a first public key, a first address and a first mnemonic corresponding to the first private key, and associates the first public key with the first The address is returned to the wallet application; the first TA generates a trusted storage key according to the user key and the HUK of the computer device; the first TA generates a file encryption key, and pairs the first private key and the first mnemonic according to the file encryption key Perform encryption, generate and store encrypted private key information; the first TA encrypts the file encryption key according to the trusted storage key, and generates and stores encryption key information. The present invention guarantees that assets will not be lost due to the theft of wallet data.
Description
technical field [0001] The present application relates to the field of Internet technologies, and in particular to a wallet encryption storage method, a signature method, a computer device and a storage medium. Background technique [0002] The current way of storing sensitive data such as private keys or mnemonics in blockchain wallets is usually to encrypt these sensitive data with the user key and store them in the hard disk. [0003] The problem with the above solution is that when the computer equipment storing encrypted sensitive data is invaded, 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 asset loss due to sensitive data such as private keys or mnemonics. SUMMARY OF THE INVENTION [0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a wallet en...
