Abstract:
Recently, Chien et al. proposed RSA-based partially blind signature with low computation for mobile and smart-card applications. Hwang et al. claimed that Chien et al.’s scheme cannot meet the untraceability property of the blind signature later. In this paper, we show that Hwang et al.’s claim is incorrect and Chien et al.’s scheme is still satisfy the untraceability property.
