In this paper, the authors present an online/offline identity-based signature scheme for the Wireless Sensor Network (WSN). The authors argue that due to significant reduction in costs of computation and storage, the scheme is particularly suitable for the WSN environment with severely constrained resources. One of the interesting features of the scheme is that it provides multi-time usage of the offline storage, which allows the signer to re-use the offline pre-computed information in polynomial time, in contrast to onetime usage in all previous online/offline signature schemes.
