  • User device performing password based authentication and password registration and authentication methods thereof
    Patent number: 10044703
    Abstract: A password registration method of a user device which uses a password-based authentication manner is provided. The password registration method includes combining a salt to an input password to generate a combination password; expanding the combination password to generate an expanded password of which a data length is increased; compressing the expanded password to output authentication data; and storing the authentication data in an authentication database.
    Type: Grant
