Abstract
A processing device comprises a processor coupled to a memory and is configured to receive authentication information from a user, to generate a message authentication code based at least in part on the received authentication information, to generate a credential for a particular access control interval based at least in part on the message authentication code and an intermediate value of a hash chain, and to provide the credential to a user in order to allow the user to access a protected resource in the particular access control interval. The message authentication code may be generated over a message payload that includes a password provided by the user. The credential may comprise a combination of the message authentication code and the intermediate value of the hash chain.
