An UF-IBSS-CMA Protected Online/Offline Identity-based Short Signature Technique using PDL

摘要

In this article, we present an online/offline identity-based short signature scheme using partial discrete logarithm (PDL). It is secure under unforgeability of identity-based short signature (IBSS) under chosen message attack (UF-IBSS-CMA) in random oracle. One of the interesting structures of our techniques is that it gives multi-time usage of the offline storage, which permits the signer to re-utilize the offline pre-processed info in polynomial time, as opposed to one-time usage in all past online/offline signature techniques. Our scheme is practical and feasible to be utilized in the wireless sensor network environment.
