The embodiment of the invention discloses a password protection method and device based on biometric identification and SM2 cooperative password algorithm. The method includes that the client receives the user's biological characteristics and passes the verification, and encrypts the plaintext passwords in turn to obtain the first ciphertext and the second ciphertext respectively; when the client receives the biometric characteristics and passes the verification, it passes the local RSA The private key signs the corresponding account ID to obtain the signature data, performs dot multiplication operation based on the local first private key component and the second ciphertext to obtain the first dot product result, and combines the first dot product result, signature data, account number The ID is sent to the server; the server uses the RSA public key corresponding to the account ID to verify the received signature data, and if the verification is passed, it uses the second private key component and the first dot product to perform a dot multiplication operation to obtain the second point Multiply the result and send it to the client; the client decrypts the second multiplication result to obtain the plaintext password. This method reduces the leakage risk of user passwords.
Description
technical field [0001] The invention relates to the technical field of information security, in particular to a password protection method and device based on biometric identification and SM2 cooperative password algorithm. Background technique [0002] In the securities industry, for reasons such as system security and stability, the background trading system only supports transaction password login, and according to security compliance requirements, it is forbidden to store passwords and encrypted data in other mid-stage systems except the counter, thus causing customers to Terminal login, must enter the pain point of the transaction password. [0003] With the popularization of mobile devices and the maturity of biometric technology, there is a demand for biometric login trading system on securities trading mobile clients. To meet this demand, developers have provided some technical solutions, basically using RSA public key to encrypt transaction passwords Stored locally...
