摘要:

根据盲签名的电子现金支付方式,提出一种改进的匿名奖励方案。该方案可保证奖励申请者匿名地提交问题解答和获得奖励,能有效地保护奖励申请者的隐私。引入(t, m)秘密共享方案,使奖励提供者通过合作获得问题解答,从而保证方案的公平性。与现有的奖励方案相比,该方案具有数据传输安全性高、密钥长度短、通信成本低等特点,在无线网络中具有一定的实用性。

Abstract:

This paper proposes an improved anonymous rewarding scheme based on the electronic cash payment on blind signature. This scheme ensures that the reward claimant anonymously submits solutions to the problem and obtains the reward so that the privacy of the reward claimant can be protected effectively. By the introduction of (t, m) secret sharing scheme, the reward provider can obtain the solution to the problem through collaboration so as to protect the fairness of scheme. Compared with the existing rewarding scheme, the scheme which enjoys some certain practicability in wireless network, has higher secrecy of data transmission, requires short secret key distance and smaller communication cost, etc.

Key words: blind signature, electronic cash, anonymous rewarding, (t, m)secret sharing, fairness, wireless network
