| 摘 要： | paillier密码体制是建立在n次复合剩余问题上的公钥密码体制,paillier在提出该公钥密码体制的同时也给出了基于paillier的数字签名方案。本文基于paillier的数字签名方案,提出了一种新的数字签名方案。与原有基于paillier的数字签名方案相比,新的签名方案的签名效率和安全性有了很大提高。基于该数字签名方案,本文设计了一种有效的群签名方案,并给出了安全性的证明。

| Abstract: | Paillier cryptosystem is a pubic key cryptosystem which is based on the Composite Residuosity Class Problem. Pascal Paillier has put forward the digital signature scheme which is based on the Paillier cryptosystem. The digital signature scheme is studied and a new digital signature scheme was proposed. Compared with the traditional Paillier signature scheme,the new scheme is more efficient and the safety has not been lowered down and an efficient group signature is designed and the proof of security is given. |
