Abstract
A technique controls a soft token running within an electronic apparatus. The technique involves providing an initial series of authentication codes based on a first set of machine states. The initial series of authentication codes is provided from the electronic apparatus to a server through a forward channel to authenticate a user. The technique further involves receiving a command from the server through a reverse channel between the electronic apparatus and the server. The reverse channel provides communications in a direction opposite to that of the forward channel. The technique further involves changing the first set of machine states to a second set of machine states in response to the command, and providing a new series of authentication codes based on the second set of machine states. The new series of authentication codes is provided from the electronic apparatus to the server through the forward channel for user authentication.
