A two-factor identity authentication method based on light wave information

Abstract

The invention discloses an optical wave information based two-factor identity authentication method. The optical wave information based two-factor identity authentication method includes that an optical wave receiver receives optical wave information emitted from a laser emitter; predetermined format of binary coding information is generated by an optical wave spectrum recognition system according to the optical wave information; the binary coding information is encrypted based on time factors by an SM3 encryption algorithm through an information encryption system and a series of digital challenge codes are generated; a user inputs the digital challenge codes into a hardware token manually and encryption conversion is performed on the digital challenge codes based on the time factors by the SM3 algorithm through the hardware token to obtain a dynamic password; the user inputs the dynamic password into an identity authentication server and the authentication is performed on a user identity through the identity authentication server according to the dynamic password. According to the optical wave information based two-factor identity authentication method, the challenge codes in the two-factor identity authentication are generated based on the absoluteness and uniqueness of the optical wave information and accordingly the challenge codes cannot be affected by single parameters such as time easily.

Description

technical field [0001] The invention relates to the field of electronic authentication, in particular to a two-factor identity authentication method based on light wave information. Background technique [0002] With the development of e-commerce and the advancement of mobile terminal technology, people use mobile terminals more and more frequently for online consumption, and electronic payment has become one of the main means of payment for people.
