This report targets the area of wireless sensor networks, and in particular their security. Probabilistic key pre-distribution schemes were developed to deal with limited memory of a single node and high number of potential neighbours. We present a new idea of group support for authenticated key exchange that substantially increases the resilience of an underlaying probabilistic key pre-distribution scheme against the threat of node capturing.
