Abstract: Identity-based cryptography (IBC) has drawn a lot of attentions in delay tolerant environment. However, the high computational cost of IBC becomes the most critical issue in delay tolerant mobile sensor network (DTMSN) because of the limited processing power. In this paper, an efficient identify-based signature scheme with batch authentication (ISBA) is proposed for DTMSN. ISBA designs an online/offline signature with batch authentication to reduce the computational cost, and improves data delivery mechanism to increase the number of messages for each batch authentication. Simulation results show that ISBA not only realizes a lower computational cost than existed schemes, but also does not induce negative impact on the delivery performance.

Key words: IBC, DTMSN, signature, batch authentication, computational cost
