There is described a device for communicating with a network. The device receives a series of paging messages from a serving node in the network, where each paging message includes identification and authentication information sufficient to identify at least one device and authenticate the message, at least some of the information having been protected according to a sequence such that it varies between successive paging messages. The device verifies the protected part of the information using a cryptographic function and knowledge of the sequence and identifies whether the information indicates that message is an authentic message intended for that device. The device may act in response to the received paging message.
