Abstract
An address-hopping method is provided to enhance security in computer networks. In embodiments, the method is carried out at a network node and includes storing an IP address that is temporarily valid as a destination address for the node; sequentially updating the stored IP address, at least at specified intervals of time, with new values that are each temporarily valid; and conditionally accepting or rejecting incoming packets according to whether there is a match between the destination IP address of the incoming packet and the temporarily valid IP address currently stored in the memory.
