- Abstract
- As wireless sensor networks are often deployed in adverse or hostile environments, key management schemes are required for sensor nodes. The random key predistribution (RKP) scheme is a probabilistic key management scheme where each node is preloaded with a subset of keys that are randomly selected from a pool of keys. If a pair of neighbor nodes have a common key, it can be used to establish a secure link between the nodes. The q-composite RKP scheme requires that a pair of neighbor nodes have at least q common keys for a secure link. In this article, we show that the previous security analysis (i.e., resilience against node capture) of the q-composite RKP scheme is inaccurate and present new formulae for resilience in the RKP scheme and the q-composite RKP scheme.
