Initial parameters
- authenticator application time step: 8 seconds
- authenticator application usage: Authentication (password validation)
- Identification time window: 2 Digipass time steps
- Synchronization time window: 1 hour= 3600 seconds
DTWAT
DTWAT= ((Time step * (ITimeWindow -1)) / 8) = ((8 * (2-1)) / 8) = 1 day
First authentication
A new user has not yet successfully authenticated:
Used time window | = max (SyncWindow, ITimeWindow * time step) |
= max (3600 seconds, 16 seconds) | |
= 3600 seconds = 450 time steps = +/- 225 time steps |
Authentication before DTWAT
The user authenticates within 1 day after the last successful verification:
Used time window | = ITimeWindow * time step |
= 2 time steps * 8 seconds | |
= 16 seconds = 2 time steps = +/- 1 time step |
Authentication after DTWAT
The user authenticates between 1 day and 449 days after the last successful verification:
Time window | = Time step + (Days lapsed * 8) |
