Abstract: A forward secure secret sharing-multisignature scheme using bilinear pairings based on the strong-RSA assumption is proposed.The security of this scheme is analyzed.In this scheme，the partial signature and the group signature are forward secure，valid group signatures can be easily produced only if all participants pool their secret shares.The validity of the partial signature and the group signature can be verified.

摘要： 基于强RSA假设，利用双线性映射的性质，提出了一种具有前向安全特性的秘密共享-多重签名方案，并对方案的安全性进行了分析。该方案中个体签名和群签名具有前向安全的性质，只有所有参与者合作才能产生有效的群签名，验证者可验证个体签名和群签名的合法性。
