A Digital Currency Scheme Based on Blind Signatures Using Chaotic Hash Functions and RSA Algorithm

Blind signature is a cryptographic technique where a signer signs a message without knowing its content, thereby protecting the privacy of the message. It is widely used in digital currencies, electronic voting systems, anonymous credentials, and other areas. In response to the shortcomings of some existing blind signature schemes in terms of security and efficiency, this article proposes a digital currency scheme based on chaotic hash function and RSA algorithm blind signatures. The chaotic hash function is used to convert digital currencies, improving the shortcomings of previous algorithms. The proposed scheme has anonymous and non-traceable characteristics, can resist various attacks, and has a relatively short processing time, with higher computational efficiency and security performance.
