The problem of establishing symmetric keys in wireless sensor networks has been extensively studied, but other aspects of key management have received comparatively little attention. In this paper we consider the problem of refreshing keys that are shared among several nodes in a WSN, in order to provide forward security. We discuss several applications that lead to sensor networks with very different properties, and we propose key refreshing schemes that are useful in each of these environments, together with resynchronisation methods that allow nodes possessing different versions of a key to arrive at a common version.
