摘要
在提名的代理签名方案中,只有被提名者能验证签名的有效性。文中分析了Park Lee提出的提名代理签名,指出他的签名体制是不安全的。最后,提出一种代理签名者提名的代理签名体制,这种签名体制能克服以上弱点。
In a nominative proxy signature scheme, only the nominee can verify the signature.In this paper, we analyze the nominative proxy scheme proposed by Park Lee. We point out that the scheme presented by Park Lee is insecure and the scheme cannot provide non-repudiation. Finally we present our proxy-nominative proxy signature schemes which overcome the weakness mentioned above.
