4. Solution description

Because of the typically remote and hostile deployment environment, it is difficult to provide effective physical protection to sensors. Rather than requiring more external protection, it is essential to enforce secure compressive data gathering along the aggregation paths for high data fidelity.

There are two typical secure data aggregation categories: hop-by-hop encrypted data aggregation and end-to-end encrypted data aggregation.

In hop-by-hop encrypted data aggregation, security and data aggregation are achieved together in a hop-by-hop fashion. That is, data aggregators must decrypt every message received, aggregate the messages according to the corresponding aggregation function, and encrypt the aggregation result before forwarding it. If an inside attacker compromises an intermediate aggregator to get the decryption key, the data confidentiality is breached. Therefore, besides that the decryption/encryption process introduces higher latency, a hop-by-hop secure data aggregation protocol cannot provide data confidentiality at data aggregators.
