Detailed Description

This abtract class embodies an H.235 authentication mechanism. NOTE: descendants must have a Clone() function for correct operation.

Member Enumeration Documentation

enum H235Authenticator::ValidationResult

Enumerator:

e_OK
e_Absent	Security parameters and Msg are ok, no security attacks.
e_Error	Security parameters are expected but absent.
e_InvalidTime	Security parameters are present but incorrect.
e_BadPassword	Security parameters indicate peer has bad real time clock.
e_ReplyAttack	Security parameters indicate bad password in token.
e_Disabled	Security is disabled by local system.
