Abstract-In this paper, a ConstrAined Random Perturbation based pairwise keY establishment (CARPY) scheme and its variant, a CARPY+ scheme, for Wireless Sensor Networks (WSNs), are presented. Compared to all existing schemes which satisfy only some requirements in so-called sensor-key criteria, including 1) resilience to the adversary's intervention, 2) directed and guaranteed key establishment, 3) resilience to network configurations, 4) efficiency, and 5) resilience to dynamic node deployment, the proposed CARPY+ scheme meets all requirements. In particular, to the best of our knowledge, CARPY+ is the first non-interactive key establishment scheme with great resilience to a large number of node compromises designed for WSNs. We examine the CARPY and CARPY+ schemes from both the theoretical and experimental aspects. Our schemes have also been practically implemented on the TelosB compatible mote to evaluate the corresponding performance and overhead.
CARPY and CARPY+ are proposed in REF .
