摘　　要：秘密共享体制是密码学的重要分支，解决了一系列具有实际应用价值的问题。而其中最安全有效的就是可验证秘密共享体制以及更加优越的可公开验证秘密共享体制.椭圆曲线加密体制（ECC）在公钥密码体制中也有相当突出的表现，其特点是可以用较小的开销实现较高的安全性，更容易计算等等。我们利用椭圆曲线上离散对数难解的问题给出一个新的秘密共享协议。Secret sharing scheme is an important primitive in cryptography.,it is used as a basic instrument to solve many problem such as key management protocl, threshold and distribute signature. Verifiable secret sharing is more safer than SSS but even in this scheme participants can only verify the validity of their own shares, so in public verifiable secret sharing it is an explicit goal that anybody can verify the participants received correct own shares. Nowadays elliptic curve cryptosystem gains a wide application in cyrptogaphy, we based on the intractable problem of discrete logarithm in ECC propose a PVSS secret sharing scheme.
