Two major concerns on the routing protocol design for wireless sensor networks (WSNs) are security and energy efficiency. Focusing on the two concerns, we present an energy-efficient secure routing protocol for WSNs. Our proposed protocol guarantees secure data forwarding in an energy-efficient manner. With the location and energy-aware characteristics for routing, our protocol gives better delivery rate, energy balancing, and routing efficiency. In addition, the proposed security mechanism ensures the data authenticity, confidentiality and data availability in the data delivery in the sense that a small number of compromised nodes in the network will not result in the compromise of security under the attack of some malicious nodes. Evaluating the proposed protocol through both simulation and analysis, we show that our proposed protocol can significantly outperform the closest routing protocols and security mechanism.
