Abstract

See full text

A method for authenticating communication traffic includes receiving an initial incoming message, sent over a network from a source address to a destination address. In reply to the initial incoming message, an outgoing message containing an encoded token is sent to the client. Upon receiving a number of further incoming messages from the source address containing the encoded token, delivery of one or more of the further incoming messages to the destination address is inhibited when the number exceeds a predetermined threshold.
