Identity authentication method, device and system

Abstract

The invention discloses an identity authentication method. An authentication end provides a decoding table for a user end, wherein the decoding table consists of m rows* n columns of first symbols, m rows are marked by m different second symbols and n columns are marked by n different third symbols; when the user end requests for authentication of the authentication end, the authentication end transmits p groups of interrogation codes consisting of m second symbols and n third symbols to the user end, each group of interrogation codes correspond to at least one of the first symbols according to the decoding table, and the user end transmits q groups of answer back codes corresponding to q groups of interrogation codes in the p groups of interrogation codes back to the authentication end according to the decoding table; and the authentication end determines that the user end passes the authentication if judging that the q groups of answer back codes exist in p groups of first symbols corresponding to the p groups of interrogation codes, wherein m, n and p are more than 2 and q is more than 1.

Description

technical field [0001] The invention relates to an authentication method, in particular to a method for a server to authenticate a user's identity, so that the user can obtain the use authority of the server or another system or conduct network transactions. Background technique [0002] Due to its simplicity, traditional passwords have always been the most basic identity authentication method for computer use. However, because traditional passwords are simple, they are easily cracked by peeping, guessing, or using Trojan horse programs and phishing methods. [0003] Therefore, in view of the above problems, it is known to propose various identity security technologies, such as PKI, OTP and other identity authentication methods to further ensure the security of users and systems. These known authentication methods all have their advantages and characteristics, but there are still two main disadvantages: 1. The user must use additional electronic devices, such as chip cards, ...

AI Technical Summary

Problems solved by technology

These known authentication methods all have their advantages and characteristics, but there are still two main disadvantages: 1. The user must use additional electronic devices, such as chip cards, card readers, password generators, etc. to perform identity authentication. The use threshold is high and the operation is inconvenient, which is not conducive to popularization; 2. Some authentication technologies still have loopholes in security, for example, OTP cannot prevent phishing

Therefore, known identity authentication methods still cannot completely prevent various network attacks
