| 摘 要： | 将一个基于GDH群的数字签名方案扩展到分布式数字签名中，并将前向安全的概念扩展到该签名方案中，提出一个有效的前向安全分布式签名方案．使用部分签名密钥安全前向更新，使集体签名安全前向更新，使得任何成员都不可能单独控制签名密钥的更新．增强密钥的安全性，使签名方案具有前向安全性．

| Abstract: | A signature scheme based on GDH group is extended to distributed digital signature scheme. An efficient forward secure distributed digital signature scheme is proposed by combining the concept of forward security. In the proposed scheme the whole signature key is updated in security by means of updating partial keys. In the proposed scheme anyone can not control the updating of signature key. So the security of the signature key is enhanced and the scheme has the charaters of forward security. |
