【摘要】 提出了限制多方验证者签名的精确定义,构造了一个有效的限制多方验证者签名方案,该方案只计算一次签名就能同时限制多个验证者验证签名,弥补了一般限制验证者签名方案只有一个限制验证者的局限。分析了在BDHP困难性假设下达到期望的安全需求。该方案不仅支持否认协议,而且比一般限制单方验证者签名方案执行多次的效率高。更多还原

【Abstract】 A precise definition of limited multi-verifier signature is presented and a new limited multi-verifier signatures scheme is proposed. In this new scheme, limiting multiple verifiers to verify the signatures is allowed by only one signature computation. The limitation of only one limited verifier in generic limited verifier signatures schemes is offset. The desired security notions are achieved based on the assumption that BDHP is intractable and the new scheme not only supports denial protocol but also has higher efficiency than performing generic limited single verifier signatures with multiple times.更多还原
