ABSTRACT
Authentication is an important security mechanism for detecting forged messages in a sensor network. Each cluster head (CH) in dynamic key distribution schemes forwards a key dissemination message that contains encrypted authentication keys within its cluster to next-hop nodes for the purpose of authentication. The forwarding path of the key dissemination message strongly affects the number of nodes to which the authentication keys in the message are actually distributed. We propose a routing method for the key dissemination messages to increase the number of nodes that obtain the authentication keys. In the proposed method, each node selects next-hop nodes to which the key dissemination message will be forwarded based on secret key indexes, the distance to the sink node, and the energy consumption of its neighbor nodes. The experimental results show that the proposed method can increase by 50-70% the number of nodes to which authentication keys in each cluster are distributed compared to geographic and energy-aware routing (GEAR). In addition, the proposed method can detect false reports earlier by using the distributed authentication keys, and it consumes less energy than GEAR when the false traffic ratio (FTR) is ≥ 10%.

Mentions: When a node in DEF forwards a key dissemination message, it selects q next-hop nodes based on the distance or hop counts from each neighbor to the sink node, the link quality from the neighbor to the sink node, and the energy consumption of the neighbor. A node receiving the key dissemination message can obtain one of the authentication keys from the message only when it can decrypt the authentication key by using one of its secret keys. Hence, the forwarding path of the key dissemination message strongly affects the number of nodes to which the authentication keys in the message are actually distributed, as shown in Figure 2.
