一种安全的群代理多重签名方案

A Group-proxy Multi-signature Scheme with Provably Secure

在代理签名方案中,代理签名人可以代表原始签名人生成签名。然而,在已知的各种多重代理多重签名方案中,多个原始签名人授权于多个代理人,只有多个代理人合作才可以代表多个原始人生成签名。该文给出了一种安全的群代理多重签名方案,在这种新方案中,多个原始签名人授权给一个代理签名群,代理签名群中的成员可以代表多个原始签名人生成签名。

Proxy signature schemes allow a proxy signer to generate a proxy signature on behalf of an original signer. However, in most previous multi-proxy multi-signature schemes, the group of original signers authorize a group of proxy signers, and only the cooperation of all signers in a proxy group can generate group-proxy multi-signatures. This paper presents a group-proxy multi-signature scheme. In this scheme, a group of original signers authorize a proxy group, the member of the proxy group can generate group-proxy multi-signatures.
