Abstract. A challenge in resource­constrained sensor networks is to
provide secure communication in an efficient manner, even in the
presence of denial­of­service attacks. In this paper, we present a
simple protocol for secret maintenance between a pair of network
neighbors. We prove that Dolev­Yao adversaries cannot compromise
the current secret shared by the neighbors, nor can they cause the
neighbors to unduly waste resources. Moreover, we show that if the
current secret between the pair is somehow disclosed, previous
secrets are not compromised nor can future secrets be compromised.
