摘要：

In a forward-secure signature scheme, a current exposed secret key can be used to obtain future secret keys which can lead to future signatures invalid. Lin et al. proposed a new method called backward-secure detection to construct forward-backward secure signature schemes to avoid this shortcoming. In this paper, we will show an attack to point out that their scheme doesn't satisfy back-ward security.
