基于防篡改Token和加密电路的指纹认证方案

针对基于加密电路的指纹认证方案运用于移动设备时所面临的带宽受限问题，提出了一种基于防篡改Token和加密电路的安全函数计算协议，该协议的使用能够明显减轻服务器与移动设备之间的通讯压力。在此基础上设计了指纹认证方案。分析和实验结果表明，该方案可以解决上述困难，并使得移动设备在指纹认证时的个人隐私得以保护。

Tamper-proof Token based remote fingerprint authentication scheme using gabled circuit

In order to solve the problems of limited bandwidth in remote fingerprint authentication using garbled circuit on mobile equipments, a novel secure function evaluation protocol based on tamper-proof Token and garbled circuit is presented. The proposed protocol can relieve the communication pressure between the server and the mobile equipments obviously. A scheme of fingerprint authentication is further designed based on the above protocol. Analysis and experimental results show that the proposed scheme is capable of solving the problems above and protecting the privacy of fingerprint in remote authentication on mobile equipments.
