摘　　要：提出一个无可信第三方的可验证的向量空间多重密钥共享方案,其安全性依赖于椭圆曲线密码学的安全性.该方案具有如下特点:无须可信第三方的参与,极大地减少了开销;由参与者联合生成共享的主密钥并分发相应的共享份额;可以共享多个主密钥,而每个共享者只须存储一个子密钥;可以有效防止内部成员的欺诈以及外部攻击者的攻击;仅需有限的存储空间和传输带宽,具有实际应用价值.A verifiable vector space multi-secret sharing scheme the security of elliptic curve cryptography. This scheme has th proposed. Its security is based on following characteristics： there is no trusted center, so the cost can be saved greatly; all the participants cooperate to generate the secrets and distribute the corresponding shares; all partici participant just needs to save one sub-key; the cheating outsiders can be detected; the current scheme is just n bandwidth, so it is valuable in practical applications. pants can share multiple secrets, but each between participants and the attack from eeds limited memory and communication
