Challenging dynamic password authentication method based on brain wave waveform characteristic

Abstract

The invention relates to a challenge dynamic password authentication method based on waveform features of brain waves. The challenge dynamic password authentication method comprises the steps of scanning user's brain waves through a brain wave scanner to generate a simulated brain wave waveform signal, transmitting the simulated brain wave waveform signal to a challenge code generation terminal, performing a waveform signal A / D conversion on the simulated brain wave waveform signal through an A / D converter to generate the corresponding binary coded message, encrypting the binary coded message based on a time factor through an SM3 encryption device to generate a digital-format challenge codes, inputting the digital-format challenge codes into a hardware token, performing encryption conversion on the digital-format challenge codes based on a time factor through an SM3 algorithm to obtain dynamic passwords, and transmitting the dynamic passwords to an identify authentication server to perform authentication by a user. By means of the challenge dynamic password authentication method, the non-uniqueness of the challenge codes is improved, difficulty in cracking of the challenge dynamic passwords is improved, and economic benefits of consumers and sellers can be guaranteed.

Description

Problems solved by technology

[0008] In order to solve the technical problem that the existing challenge-type dynamic password authentication method is susceptible to the influence of a single parameter such as time in the challenge code generation process and cause the technical problem that the challenge code is not unique, the present invention provides a challenge-type dynamic password based on the characteristics of the brain wave waveform The authentication method, due to the uniqueness of the brainwave waveform characteristics, uses brainwaves and time-based algorithms to generate challenge codes. Compared with the existing technology that only uses challenge codes generated by time factors, the present invention can improve the incompatibility of challenge codes. Uniqueness, so that each user's challenge dynamic password is not unique, while ensuring the reliability of verification, it increases the difficulty of being cracked, thus ensuring the security of the identity authentication system
