To date existing key management solutions based on either public key infrastructures (PKI) or key pre‑distribution scheme (KPS) exhibit limitations for WAHNs. We firstly develop the Hybrid Key Management Infrastructure (HKMI) for WAHNs composed of moderate‑resource devices. The HKMI complements PKI with trust and cooperation protocols to construct an performance efficient security solution. We secondly develop the Deterministic Pairwise Key Pre-Distribution Scheme (DPKPS) for large‑scale dynamic WAHNs composed of low‑resource devices. The DPKPS applies a combinatorial design for the pre-distribution of multiple bivariate polynomial shares to WAHN nodes. Future work comprises further improving the resiliency of the DPKPS, completing a key management infrastructure on the basis of the DPKPS, the design of DPKPS‑based access control mechanisms, and the integration of the HKMI with the DPKPS in a unified key management architecture.}, subject = {Ad-hoc-Netz; Verteiltes System; Key management; Sicherheit; Schl{\"u}sselmanagement; Ad-hoc-Netz; Security; Key management; Ad hoc networks}, language = {en} }
