Method, system and device for authenticating read-later clients

The invention discloses a method, system and device for authenticating read-later clients. The method comprises the following steps that: a read-later client sends timestamp request information to a read-later server, acquires a timestamp from the read-later server, and generates a data security signature according to account data corresponding to the read-later client, encryption information required by the generation of the data security signature and the timestamp; the read-later client sends the data security signature and scheduled information to the read-later server, so that the read-later server carries out authentication on the read-later client according to the data security signature and the scheduled information; and the read-later client receives the authentication data sent by the read-later server, and carries out interaction with the read-later server by using the authentication data.
