Non-Interactive Key Establishment in Mobile Ad Hoc Networks ⋆

We present a new non-interactive key agreement and progression (NIKAP) scheme for mobile ad hoc networks (MANETs), which does not require an on-line centralized authority, can non-interactively establish and update pairwise keys between nodes, is configurable to operate synchronously or asynchronously, and supports differentiated security services w.r.t. the given security policies. NIKAP is valuable to scenarios where pairwise keys are desired to be established without explicit negotiation over insecure channels, and also need to be updated frequently
