| 摘 要： | 提出了基于多线性映射的环签密广播方案,环成员代表环群体匿名签密并广播给多个接收者。其具有两个用户群之间环签密通信的功能。该方案满足环签密广播的安全要求,能够保证签密所传输消息的保密性、签密的不可伪造性、签密者的匿名性。在随机预言模型下,把方案的安全性归约到分级Diffie-Hellman判定问题(GDDH)进行求解。

| Abstract: | We proposed a ring signcryption scheme based on multilinear maps.Each ring member can represent ring group to generate anonymous signcryption and broadcast it to multiple recipients.Ring signcryption can be communicated between two ring groups.The scheme meets the security requirements of ring signcryption broadcasting like the confidentiality of messages,unforgeability and anonymity.In the random oracle model,the security of the scheme is reduced to grading decisional Diffie-Hellman problem (GDDH) to solve. |
