Abstract

Abstract: An original signer may authorize a proxy signer for signing a message on behalf of the original signer in the known schemes while the proxy signer based on conic curves over Z_ncan not continue to authorize the others.But in some cases，the proxy signer needs to continue to authorize the others.So a multiple grade proxy multiblind signature scheme based on conic curves over Z_nis proposed.This paper gives proofs of the correctness and the analysis of security of the scheme.

Key words: conic curves, blind signature, multiple grade proxy signature, multiple signature

摘要： 在已知的基于环Z_n上圆锥曲线的各种代理方案中，原始签名人和代理签名人只能进行一级代理。但在有些情况下，签名权利需要逐级向下代理，而已知的方案不能满足这种需求。提出了一种基于环Z_n上圆锥曲线的多级代理多重盲签名方案。对方案的正确性进行了证明、对方案的安全性进行了分析。
