高效的基于身份的代理盲签名

在代理签名方案中，原始签名人能将其数字签名权力委托给代理签名人。在盲签名方案中，消息和签名结果对签名人是不可见的。现有的基于身份的代理盲签名的文献数量少，效率也有待进一步提高。结合代理签名和盲签名，利用双线性映射，构造了一种高效的基于身份的代理盲签名方案。分析表明，该方案不仅能满足代理盲签名所要求的所有性质，而且其效率也优于已有文献。

Efficient identity-based proxy blind signaturee

With proxy signature, an original signer can entrust his signing authority to a proxy signer. In blind signature scheme, a message and the signature result was unknown to the signer. An efficient identity-based proxy blind signature scheme was proposed by using bilinear pairings and combining proxy signature with blind signature. Analysis shows that the proposed scheme can satisfy all the required properties of a proxy blind signature. Furthermore, its efficiency is also better than that of the existing ones.
