摘要:Identity-based signature (IBS) scheme can be widely used in resource-limited situations such as mobile e-commerce. In this paper, a lattice-based IBS scheme is first established by using trapdoor generation algorithm GenTrap, preimage sample algorithm SampleD and trapdoor delegated algorithm DelTrap put forward by Micciancio and Peikert in Eurocrypt’12; then the proposed scheme is proven to satisfy strong unforgeability against selective ID and static chosen massage attack in the standard model based on small integer solutions (SIS); and finally the proposed scheme is compared with the existing similar scheme in computing performance. The results show that the scheme presented in this paper enjoys the highest efficiency.
