Remark on Yu et al.s Online/Offline signature scheme in CT-RSA 2008

摘要：

CT-RSA 2008, Yu et al. proposed a family of three efficient Online/Offline signature schemes, which are especially suitable for the devices with limited computing capabilities. In this paper, we propose a new security model of Online/Offline signature. We find that Yu et al.basic scheme is insecure under our model. We repair Yu et al.s loophole by proposing a modified scheme.
