The embodiment of the invention discloses a password protection method and device based on biological recognition and an SM2 collaborative cryptographic algorithm. The method comprises the following steps: a client receives biological characteristics of a user, verifies the biological characteristics, and encrypts plaintext passwords in sequence to respectively obtain a first ciphertext and a second ciphertext; when the client receives the biological characteristics and passes verification, signing a corresponding account ID through a local RSA private key to obtain signature data, performing point multiplication operation based on a local first private key component and a second ciphertext to obtain a first point multiplication result, and sending the first point multiplication result, the signature data and the account ID to a service terminal; the service terminal verifies the received signature data by using an RSA public key corresponding to the account ID, and if the verification is passed, point multiplication operation is performed by using a second private key component and the first point multiplication result to obtain a second point multiplication result, and the second point multiplication result is sent to the client; and the client decrypts the second click multiplication result to obtain a plaintext password. The method reduces the leakage risk of the user password.
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...
