    摘要: Methods and arrangements for supporting a forwarding process in routers 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 and a receiver are encoded. A name server generates and distributes router-associated keys to routers in the network which keys are used for computing the hierarchical parameters.

    摘要: A method of providing packet routing information comprises: encoding routing information from a source node to one or more destination nodes into a compact representation of set membership; and putting the compact representation of sets into a header of a packet that is to be sent from the source node to the destination node(s). The compact representation may be obtained by: generating d representations of a set of identifiers; generating d candidate compact representations of set membership from the d representations of the identifiers; and selecting one of the candidate compact representation of set membership. The selection may be made on the basis of which of the candidate compact representations has the lowest rate of returning false positives.

    摘要: A method of delegating responsibility for an IP address owned by a first IP network node to a second IP network node, at least a part of the IP address being derivable from a public key of a public/private key pair belonging to the first node. The method comprises notifying the first node of a public key of a public/private key pair belonging to the second node, at the first node, signing the public key of the second node with the private key of the first node to provide an authorisation certificate, and sending the authorisation certificate from the first node to the second node, wherein the authorisation certificate is subsequently included with messages relating to said IP address and signed with the private key of the second node, sent from the second node to receiving nodes, and is used by the receiving nodes to verify the second node's claim on the IP address.

    摘要: A method of improving privacy by hiding, in an ordered sequence of messages M[x(1), D(1)], M[x(2), D(2)], etc, communicated between a first and at least one second party sharing a key k, metadata x(i) descriptive of message processing, wherein D(i) denotes payload data. The method comprises the first and the second party agreeing on a pseudo random mapping depending on a shared key k, Fk, mapping at least x(i) to y(i), and the first party modifying the messages by replacing x(i) by y(i) in each message M(x(i), D(i)). The first party then transmits the modified messages maintaining their original order, and on reception of a message M(y(m), D), the second party uses a mapping Gk to retrieve position m of received value and the original value x(m).

    摘要: A network node (NB1) located within a domain is adapted to receive, from another node, a packet having an in-packet Bloom filter or Bloom filter equivalent encoding information about a route within the domain. The node reversibly modifies the in-packet Bloom filter or Bloom filter equivalent in a manner which is linear with respect to the operation used to add links to the Bloom filter or Bloom filter equivalent. The node then forward the packet with its header containing the modified Bloom filter or Bloom filter to another node (NA1). The invention allows secure Bloom filter-based routing in a domain (Domain B), while requiring that only routers (NB1) at the domain boundary are secure routers. Other routers (NB2, NB3, NB4) in the domain may operate conventionally, and may be secure routers or insecure routers. The modification may be a bit permutation.
