Abstract: In this work, we propose a key certification protocol for wireless sensor networks that allows nodes to autonomously exchange their public keys and verify their authenticity using one-way accumulators. We examine and compare different accumulator implementations for our protocol on the Sun SPOT platform. We observe that our protocol performs best with accumulators based on Elliptic Curve Cryptography (ECC): ECC-based accumulators have roughly the same speed as Secure Bloom filters but they have a smaller memory footprint.

CALIPSO workshop at FIA, 7th May 2013, Dublin

Calipso proposes to organize a half-day workshop on networking aspects
related to Sensor Networks and Smart Objects. The Internet of Things puts forward
the vision of interacting with the physical world by interconnecting objects having
advanced processing, communication, sensing, and actuating capabilities. The
Internet of Things is also increasingly enriched with the new communication devices
that allow people to communicate and connect to all kinds of objects. The emerging
technologies of the Internet of Things begin to interconnect physical world objects
and places with people transforming citizens’ interactions with the surrounding world
and influencing how they live, travel, and spend their leisure time.

The program is available online.
