Abstract(in English) We address a secure routing in delay tolerant networks (DTNs) that lack continuous network connectivity. While cryptographic operations are powerful tool to protect encrypted data for end-to-end communications, outright prevention, i.e., avoiding insecure area where adversaries are located, is an ideal solution. To this end, we first formulate a new class of routing problem, called {it contact avoidance}, in which the node with a message tries to avoid having a contact with adversaries. Then, we studied on a contact avoidance routing protocol and demonstrate that the proposed scheme significantly improves the secure delivery rate by simulations.
