摘要
针对动态车辆保险评估中的隐私需求,设计了一种可转换的环签名方案.首先,结合椭圆曲线线性运算性质进行方案设计,提高了对同一群组的多个签名进行验证的效率;其次,设计了匿名签名到普通签名的选择性转换机制,用于验证用户是否为数据属主.实验结果表明,在签名用户数量较大的情况下,所提方案的签名验证效率比其他方案更高;在签名群组和签名数量都增大的情况下,所提方案仍具有较好的性能.
Abstract
For the privacy requirements in dynamic vehicle insurance assessment, a convertible ring signature scheme is designed.Firstly, the scheme is combined with the linear operation property of elliptic curves to improve the efficiency of verifying multiple signatures of the same group.Secondly, a selective conversion mechanism from anonymous signatures to ordinary signatures is designed to verify whether the user is a signed data owner.Experimental results show that the signature verification efficiency of the proposed scheme is higher than that of the existing schemes with larger number of users.And the proposed scheme maintains good performance when both the signature group and the number of signatures are increasing.
