Embodiment Construction

[0016] The invention relates to a dynamic token time error correction method for an authentication system, comprising the following steps:

[0017] 1) Set the time window t in the authentication center;

[0018] The time window t is the range of time change, and it is also the maximum range where the time error of the dynamic token may exist. Its unit is minutes, and the second part of the time is omitted.

[0019] 2) Record t through token timing 0 , the token can display the dynamic password P at the current time T ;

[0020] said t 0 is the error between token time and system time, t 0 The unit is minutes, and the second part of the time is omitted. P T It is the dynamic password of the current time displayed by the token.

[0021] 3) Perform dynamic password comparison, and the system calculates P T1 =F(T 1 +t 0 , K), the P T1 with P T comparing;

[0022] T 1 is the current time, T 1 The unit is minutes, and the second part of the time is omitted.

Abstract

The invention aims to provide a dynamic token time error correction method for an authentication system, which effectively solves the problems of complex operation, low accuracy degree, and great potential safety hazard in the conventional token time correction technology. By adopting novel dynamic token time error tracking technology, the method can correct the time in the using process each time without opening the token, and the problem of error accumulation is avoided. Therefore, the dynamic token time error correction method eliminates the potential safety hazard of the token in structure and greatly reduces the using risk of a user on the basis of ensuring the token accuracy and availability. Due to the adoption of a two-factor authentication time shift tolerance mechanism, the dynamic token time error tracking technology is realized.

Description

technical field [0001] The invention relates to a dynamic token time error correction method used in an authentication system. Background technique [0002] With the development of communication technology and computer technology, people pay more and more attention to information security technology, and identity authentication technology is an important topic in the field of information security. In order to ensure that before users access any system, they must first pass some kind of identity authentication mechanism to verify whether the user's identity is legal. Only after the identity authentication is successful, can some resources of the system be accessed or an operation be performed according to the legal identity of the user. [0003] In the field of identity authentication, passwords are indispensable, and conventional passwords are easily cracked by high-level technicians, so people have developed dynamic password technology. The core of the so-called dynamic p...
