摘要: 通过把矢量空间秘密共享方法与代理多重签名相结合,提出了一种新的代理多重签名方案。该方案满足原始签名人不可伪造性、代理签名不可伪造性、代理签名的可区分性、代理身份真实性、密钥依赖性以及可注销性等6 条性质。通过安全性分析,可以得出这是一种安全的签名方案。

Abstract: With the combination of vector space secret sharing method and proxy multisignature scheme, a new proxy multisignature scheme is presented. This scheme can satisfy the following properties: the signature of original owner can’t be forged; the proxy signature can’t be forged; the proxy signatures can be distinguished from the original one; the identity of the proxy can’t be forged; secret key should rely on the original owner and the last is the proxy signature can be logout by the original owner. With the security analysis, it is a secure signature scheme

Key words: Vector space secret sharing; Proxy multisignature; Discrete logarithm
