摘要：
A method for providing authentication of a user of a recipient unit when the recipient unit is off-line includes storing one or a plurality of challenge-reply sets associated with an article based on an on-line communication with a sender unit. Each of the challenge-reply sets includes at least a challenge-reply pair for use in off-line authentication of the user for a particular resource available through the recipient unit. When the user is offline, the method includes selecting at least one of the plurality of stored challenge-reply sets for off-line authentication of the user for the particular resource available through the recipient unit.
