【摘要】 通过将随机数的不确定性和Hash函数的单向性应用到弱盲签名方案之中,建立一种不可追踪的强盲签名方案,并在此基础上构造了一种多重盲签名方案。该方案既可以保持用户隐私性,又增加了安全性,在电子支票支付实际应用中有一定推广价值。更多还原

【Abstract】 In this paper,the authors introduce three random numbers and the Hash function to the weak blind scheme in order to solve the problem of signature traceable in some known blind signature schemes.Then,the authors propose an untraceable multi-blind signature scheme to keep not only the privacy but also the security in a proper environment which can be put into practice in the application of e-check payment.更多还原
