> 中文摘要: 给出了前向安全多重签名的形式化安全性模型,并提出了一个可证安全的前向安全多重签名方案。在该方案中,即使所有参与多重签名成员的当前密钥泄漏,所有以前时间段的签名也是有效的。证明了方案是标准模型下安全的。
Abstract:The formal security model of forward-secure multi-signature is examined and a forward-secure multi-signature scheme with provable security is proposed. Even if the current secret keys of all the signers are exposed, all the signatures pertaining to previous periods are still valid in this scheme. The presented scheme has proven to be secure in the standard model.
