An E-cash Systems with Non-repudiation Based on Zero-knowledge Proof
|
Abstract:
Most e-cash systems have anonymity to protect users' privacy, but few of them provide the non-repudiation service such that many problems such as blackmailing , money laundering , losing, misusing and double-spending can been avoided. Based on the partial blind digital signature and zero-knowledge proof,an e-cash system with non-repudiation is constructed in the article.
