Meigen Huang, Bin Yu, Sensen Li · IEEE Communications Letters · 2017
In this letter, a novel group key distribution scheme based on physical unclonable functions (PUFs) is proposed for software-defined wireless sensor networks. The PUF is difficult to be cloned and predicted, remarkably enhancing physical security performance of sensor nodes. In addition, under the centralized management of software-defined networking, PUF challenge is stored in the sensor nodes to minimize communication overhead. The proposed algorithm achieves group key delivery with two-way authentication function through one communication interaction. We demonstrate the scheme can resist multiple attacks, including cloning, eavesdropping, and so on, thus effectively guaranteeing the security and efficiency of group key distribution process.
