Limited Proxy Digital Signature Schemes

Abstract

Abstract: In this paper, the one-time proxy signature scheme and time-limited proxy signature scheme are proposed. In first scheme, the proxy signer can only sign one proxy signature each time, in case the proxy signer violates this condition, the original signer can show the evidence by revealing the private key of the proxy signer. The second scheme can limit the signature time of the proxy signer. These schemes will be applied in e-commerce and other fields.

摘要： 提出了一个一次性代理签名方案和一个时控代理签名方案。采用一次性方案，代理签名人如果签署两次以上的签名，则他的密钥会被破译。第二种方案可限定代理权限的有效期限。这些方案在电子商务和其它领域有广泛应用。
