| Research Abstract |
We proposed an efficient and optimally secure sensor network aggregation protocol against multiple corrupted nodes by a random-walk adversary. Our protocol achieved one round-trip communication to satisfy optimal security without the result-checking phase, by conducting aggregation along with the verification, based on the idea of TESLA technique. We also showed that the congestion complexity, communication complexity and computational cost in our protocol were constant, i.e., O(1). Furthermore, we proposed a basic MAC aggregation protocol.
