Secure Data Aggregation in Wireless Sensor Networks
Abstract—
Secure data aggregation in wireless sensor networks has two contrasting
objectives, i) Efficiently collecting and aggregating data and ii) Aggregating the
data securely. Many schemes do not take into account the possibility of corrupt
aggregators and allow the aggregator to decrypt data in hop by hop algorithms. On
the other hand using public key cryptography for providing end to end security is
not energy efficient. In this paper we present and analyze the performance of the
secure hierarchical data aggregation algorithm which uses an efficient public key
cryptosystem (elliptic curve cryptography) to achieve end to end security. Unlike
many other secure data aggregation algorithms which require separate phases for
secure aggregation and integrity verification, the secure hierarchical data
aggregation algorithm does not require an additional phase for verification. This
saves energy by avoiding additional transmissions and computational overhead on
the sensor nodes. We present and implement the secure data aggregation algorithm
on Mica2 and TelosB sensor network platforms and measure the execution time
and energy consumption of various cryptographic functions. We have also
simulated our algorithms to analyze how an end to end scheme increases the
network life time. We experimentally analyze our algorithms based on parameters
like throughput, end to end delay and resilience to node failures.
