摘要
提出一种基于椭圆曲线加密的非交互式零知识证明协议,并基于该证明协议提出一个可公开验证的密钥共享方案.在该方案中,密钥和密钥份额被嵌入椭圆曲线的点上,任何人均可对密钥和密钥份额进行验证,只有合法参与者集合可恢复出密钥,但无法知道密钥的具体内容;这样有效阻止了攻击者窃取密钥,也防止了数据的误发和成员之间的欺诈,更有利于密钥的复制与更新.
A non- interactive zero- knowledge proof protocol based on Elliptic Curve Encryption was proposed, and based this protocol, a publicly verified secret sharing scheme was proposed too. In the scheme, secret and secret shadow were embedded onto the points of Elliptic Curve, anybody can verify them publicly, and only the legitimate participants set can recover the secret key, but knowing nothing about the secret key. This scheme can prevent adversaries from getting the secret, the dealer from distributing improper data and the participants from cheating each other efficiently. Furthermore, it is propitious for the replication and update of secret.
