The Application of Blind Signature Based on RSA Algorithm

With the development of electronic commerce, the anonymity of the user on the consumption demand is increasingly outstanding. Electronic cash as a result of this demand arises. In an open network environment, how to protect the integrity, authenticity and integrity of electronic cash transaction has become the focus of current research. This paper mainly discusses electronic cash system based on blind signature. Using RSA blind signature guarantees the system's anonymity. It also analysis the system's safety, and gives the solution method.
