CDA: concealed data aggregation for reverse multicast traffic in wireless sensor networks

摘要: End-to-end encryption for wireless sensor networks is a challenging problem. To save the overall energy resources of network, it agreed that sensed data need to be consolidated and aggregated on their way final destination. We present an approach (1) conceals end-to-end, by (2) still providing efficient in-network aggregation. The aggregating intermediate nodes are not required operate plaintext data. apply particular class transformation exemplarily discuss basis two aggregation functions. use actual implementation show feasible flexible frequently even more than hop-by-hop encryption.
