Network-reprogramming is a valuable service for maintaining sensor
networks. Network-reprogramming services need to be not only
efficient and reliable, but secure as well. A number of strategies for
providing authentication and integrity have been proposed and evaluated,
but the tradeoff space has yet to be explored to any significant
depth. The recently proposed strategies are mainly distinguished
through their structure, granularity and strength of hashing. We propose
a configurable, secure data dissemination scheme that uses a different
hash-structure to allow for a high degree of flexibility in choosing
from a full spectrum of hash granularities and strengths. Using this
structure, we are able to experimentally explore the tradeoffs inherent
in choosing a hash-granularity under different attack scenarios and
densities.
