Secure and energy-efficient data aggregation with malicious aggregator identification in wireless sensor networks ☆

摘要: Data aggregation in wireless sensor networks is employed to reduce the communication overhead and prolong network lifetime. However, an adversary may compromise some nodes, use them forge false values as result. Previous secure data schemes have tackled this problem from different angles. The goal of those algorithms ensure that Base Station (BS) does not accept any forged results. But none tried detect nodes inject into bogus Moreover, most usually a (at best) logarithmic per node. In paper, we propose energy-efficient scheme can malicious with constant node overhead. our solution, all results are signed private keys aggregators so they cannot be altered by others. Nodes on each link additionally their pairwise shared key for communications. Each receives its parent (sent parent) siblings (via node), verifies result Theoretical analysis energy consumption accords comparison based simulation study over random trees.
