That is, both the joining node and its parent should update their parent/children information. Figure shows the sequence diagram that demonstrates how a joining node finds the best free position in the tree. Compute new keys: We proposed in our previous work to update keys that exist in the same branch of the joining node. The other branches have to update their certificates.…”

Secure communication of Internet of Things (IoT) devices relies on cryptographic approaches whose robustness is based on the security of encryption keys. For instance, an adequate key management scheme must be used to properly manage the used keys. Designing an efficient and robust key management scheme for the connected devices is a challenging task. Reported key management schemes suffer from several deficiencies such as the single point of failure and the non–trade‐off between scalability, connectivity, and resiliency. This paper first reviews key management schemes in the context of the IoT. Then, we propose a collaborative lightweight key management scheme that secures the keys during the life cycle of the embedded devices. Our proposal relies on the collaboration of the smart devices, where all the devices participate in the construction of the global key. Following the analytical and the comparative studies, we show that our proposal can be integrated in several communication protocols designated for embedded devices such as IEEE 802.15.4. Simulation results validate the analytical study and show that the proposed collaborative group key scheme exhibits superior performance when compared with two corresponding schemes reported in the literature.
