An enhanced RSA-based partially blind signature
Dejian Fang, Na Wang, Chenglian Liu · 2010
Hwang et al. showed that the Chien et al.'s partially blind signature scheme based on RSA public cryptosystem could not meet the untraceability property of a blind signature. In this paper, we proposed an enhanced version of Chien et al.'s partially blind signature scheme based on RSA. This enhancement eliminates the vulnerability of the original version to the trace attack.
