A challenging dynamic password authentication method based on brainwave waveform characteristics

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

technical field

[0001] The invention relates to the field of electronic authentication, in particular to a challenge-type dynamic password authentication method based on brain wave waveform characteristics. Background technique

[0002] The networking of information application systems brings about data security issues while achieving information sharing and extensive and in-depth applications. Illegal interception, fraudulent use or damage, information security issues have also become one of the most concerned issues. The simplest static password used to determine the identity of a legitimate user can no longer keep up with the pace of network technology development, and it is easy to be guessed or obtained through interception, or even leaked because it is seen when entering the password. Therefore, in order to improve people's confidence in conducting transactions through the network, the technical content of identity authentication must be improved.
