Abstract: A forward secure blind proxy re-signature scheme based on the difficulty assumption of quadratic residues is presented,which is bidirectional.The scheme is safe under the random oracle model.The scheme can maintain the former signature’s safety even if current cycle’s signature key is leaked,and the scheme can make the message transparent.
Key words: quadratic residues, blind signature, proxy re-signature, forward-secure, random oracle model
摘要: 提出了一个具有前向安全的盲代理重签名方案,并在随机预言机的模型下证明了该方案能抵抗伪造攻击的特性。该方案除了具有消息透明性外,还能保证即使当前周期的签名密钥被泄露,也并不影响此周期前签名的有效性。
