Ring signcryption scheme based on domestic cryptographic algorithm SM9
Tongxin xuebaoTo address the linear computational increase with ring size in existing identity-based ring signcryption schemes, an efficient ring signcryption scheme based on the Chinese national cryptographic standard SM9 was proposed.

An ID-based Anonymous Signcryption Scheme With Self-verifiability For General Access Structure [PDF]
, 2011 基于身份的环签密结合了环签名和基于身份的签密这两种密码体制的优点，实现了以既保密又匿名认证的方式传输信息，但在传统的基于身份的环签密方案中，通常只考虑用户群是由多个单一用户组成的情况，而未考虑群中的用户是由成员个数不同的“小群体”构成的情况。 据此本文利用双线性对构造了一个在访问结构上的基于身份的匿名签密方案，并在随机预言模型中给出了安全性的证明。同时该方案具有消息的保密性、不可伪造性、签密者身份的模糊性、公开可验证性、可自证性。 本文的结构安排如下： 第一章介绍论文的研究背景以及论文的主要工作 ...

Identity Based Reception Threshold Ring Signcryption Scheme
, 2012 签密能够以较低的通信成本同时完成认证和加密2种功能.为了同时实现匿名加密、认证和门限解密3种功能,提出了基于身份的接收门限环签密方案,并在随机预言模型下证明了其安全性.在这个方案中,任何人能任意选择n-1个成员,加上他自己构成一个群.然后代表这个群生成一个签密,把密文发送给特定M个人,只有至少其中T≤M个人合作才能恢复消息.本案在签密阶段只需要1次双线性对计算,解签密阶段也只需要3次双线性对计算.Signcryption offers authentication and confidentiality

Analysis and Enhance of Anonymous Signcryption Scheme
, 2009 Ring signcryption, a cryptographic primitive to protect security and privacy, is an encryption and authentication scheme in a single logical step which allows a user to anonymously signcrypt a plaintext on behalf of a group of users that decrypter cannot
