应用量子盲签名和群签名的电子支付系统

摘要

提出了一个基于量子群签名和盲签名电子支付系统的实现方案.基于经典的签名的现有的电子支付系统不能保证无条件安全性.与经典的电子支付系统不同,提出的方案既能满足电子支付系统的需求,又能实现无条件安全.应用量子密钥分发技术,量子一次一密算法和审计机制实现了基于量子签名的电子支付系统.%A new e-payment system based on quantum blind and group signature is proposed.Existed e-paymcnt systems which based on the classical cryptography cannot guarantee the security because of the unsecure of classical blind and group signature.Compared with the classical e-payment system,this quantum e-payment scheme can realize not only the function of e-payment but also the unconditionally security.To achieve that,quantum key distribution,one-time pad and quantum blind and group signatures are adopted in this scheme.Moreover.the mechanism of audit is introduced to detect the forgery.
