摘要: 无线通信终端处理能力和响应速度能力有限,普通的数字签名方案无法适用。为此,结合优化的在线/离线签名,构造一种无证书的在线/离线盲签名方案。在签名过程中,大部分运算在盲消息给出之前进行,在给出盲消息之后,再进行少量运算得出签名,签名人并不知道所签文件内容。性能分析结果表明,该方案可以应用在无线网络上,用于保护用户隐私。

Abstract: The processing ability and response speed of the wireless communication terminals are limited, common signatures become the bottleneck to the development of the wireless networks. For that problem, the certificateless on-line/off-line blind signature is given in this paper which incorporates with the optimal on-line/off-line signature. Most computations are finished before the blind message is given, after that, only a few operations are needed. Results of performance analysis show that the signature scheme can be applied to the wireless network, and it can protect the users’ privacy efficiently.

Key words: digital signature, bilinear mapping, on-line/off-line signature, blind signature, wireless network
