Query: On secure communication in sensor networks under q-composite key
  predistribution with unreliable links   Many applications of wireless sensor networks (WSNs) require deploying
sensors in hostile environments, where an adversary may eavesdrop
communications. To secure communications in WSNs, the q-composite key
predistribution scheme has been proposed in the literature. In this paper, we
investigate secure k-connectivity in WSNs operating under the q-composite
scheme, in consideration of the unreliability of wireless links. Secure
k-connectivity ensures that any two sensors can find a path in between for
secure communication, even when k - 1 sensors fail. We present conditions on
how to set the network parameters such that the network has secure
k-connectivity asymptotically almost surely. The result is given in the form of
a sharp zero-one law.
