Research on Blind Signature Based Anonymous Electronic Cash Scheme

Abstract

With the development of network economy, as a new transaction method, electronic cash makes online transactions become more convenient. However, online transactions also bring the risk of user privacy disclosure, which has attracted wide attention. To solve this problem, this paper proposes a new blind signature scheme based on RSA and applies it to electronic cash system. The electronic cash scheme increases the difficulty of analyzing the relationship between electronic currency addresses by confusing the relationship between the user’s public address and the actual address, which improves the privacy protection level of the proposed electronic cash scheme. The proposed anonymous electronic cash system can be used to protect the privacy of user identity and complete user anonymous transactions and meet the security and efficiency requirements. Finally, the performance analysis shows that the communication cost of anonymous electronic cash system in this paper is low, which significantly improves the security of electronic cash anonymous transactions and has a good application prospect.
