Secure identity-based online/offline signature system

Abstract

The article introduces an identity-based online/offline signature system for wireless sensor network (WSN). The authors claim that when the computation cost is low, the proposed system is more suitable for WSN. The authors also claim that their scheme provides multi-level use from offline information allowing the signer to reuse this before the calculated data within a limited time, unlike those used in the existing online/offline signature systems. The introduced system gave a promising outcome when used with a MICAz platform. MICAz platform is the mote 2.4HGz module wireless measurement system used for low-power WSN.
