| 中文摘要: |
| 分析了DuoLiu 等人提出的基于椭圆曲线自双线性映射的多秘密共享方案，发现该方案易遭受分发者/参与者欺诈攻击和广播窃听攻击，并依赖安全信道；提出了一种基于单向散列函数、密钥协商协议和动态多方Deffie-Hellman 协议的改进方案, 改进方案能抵抗分发者/参与者欺诈攻击和广播窃听攻击，并使方案摆脱对安全信道的依赖. 最后对改进方案的安全性进行了分析. |
| 英文摘要: |
| Duolius multi-secret sharing scheme based on self-bilinear pairing over elliptic curves is analyzed. Duolius Scheme is found vulnerable to dealer/participant fraud attack, broadcast wiretap attack, and dependent on secure communication channel. An improved scheme based on hash function, key agreement protocol, and dynamic multi-party Deffie-Hellman protocol is proposed to eliminate the above deficiencies. Security performance is discussed in the end. |
