Emergency Message Delivery in NDN Networks with Source Location Verification

During a disaster or a catastrophic accident, it is difficult to keep providing circuit-switching based emergency communication, such as the 911 calls in the US and the 119 calls in Japan, due to heavy congestion or network failures. In order to provide stable emergency message delivery, we proposed the architecture that provides packet-switching based emergency message delivery on top of NDN (Named Data Networking) networks. The architecture, however, assumes that devices in the architecture are honest. In contrast, the paper re-designs the architecture, assuming that end devices are dishonest. That is, an end device is either malicious or compromised by an attacker and tries to report a fake location to disturb the emergency message delivery service. We first define security requirements for emergency message delivery and next re-design the architecture so that it satisfies the security requirements by carefully combining an authentication mechanism, a digital signature and a location verification protocol.
