METHOD AND APPARATUS FOR SECURE ROUTING OF DATA PACKETS

摘要

Methods and arrangements for supporting a forwarding process in routers (R1-R3) when routing data packets through a packet-switched network, by employing hierarchical parameters in which the hops of a predetermined transmission path between a sender (A) and a receiver are encoded. A name server (300) generates and distributes router-associated keys (K, K1-K3) to routers in the network which keys are used for computing the hierarchical parameters.
