Improved Untraceable Blind Signature Scheme
Yuanyuan Chen · Journal of Chongqing Institute of Technology · 2008
This paper analyses one untraceable blind signature and multi-blind signature scheme advanced by Qiu Cheng Gang and Li Fang Wei is analyzed,and finds that this scheme can be followed up.In terms of insecurity in the scheme,this paper proposes an improved untraceable blind signature scheme to overcome the pointed out drawbacks,which has untraceable quality and can keep the privacy of the users,and can be applied to electronic cash.Hash function is not involved in the study,but one random number on the basic of discrete Logarithm difficult solved is introduced.The computation quantity is small,so it has some practicality.
