摘　　要：当不同权限的刑侦人员对公安刑侦系统进行业务操作时,极易产生刑侦系统的并发瓶颈和网络带宽瓶颈。将代理盲签名和椭圆曲线上双线性对运算的特性相结合构建一个实用的多权限系统,使高权限操作者适时将案件签名审批权转授给下属操作者完成,在不影响系统安全性情况下能够有效提高系统的工作效率。When different investigators permission to conduct business on the Investigative system operation is very easy to create concurrent criminal investigation system bottlenecks and network bandwidth bottlenecks.Proxy blind signature and the elliptic curve pairing operation combines the characteristics of a practical multi-authority system,so that the operator of high authority for approval in due course sign the case to the right to delegate to a subordinate operation to complete,without affecting the system security cases,improve the efficiency of the system.
