Abstract: Due to the constraints of sensors networks, implementing a secure network requires the development of new approaches dedicated and adapted to these networks. In this context, we proposed in this paper a new cryptographic solution based on grouping a modified AES in CTR mode and a new key management protocol. The originality of our solution is to obtain a high security level with regard to a minimal resources use (storage only three keys whatever the network density). Our goal is to secure communications between nodes. Simulations are executed by OMNet++ and Visual C++ Studio. Compared to existing protocols, our cryptographic solution presents better results in WSN metrics: it achieves lower energy consumption (the energy cost does not exceed 0.512 µj), loss of packets and control overhead and higher average throughput (it achieves 45,177 bps), data freshness and better packets send ratio. Also, it resists against several attacks: jamming, node capture, etc.
