摘要

在本文中，我们提出了一种新的密码原语，称为可重用群模糊提取器（RGFE），允许群中的任何成员从模糊和非均匀的高熵源（称为指纹）中提取和再现随机串。任何群组成员都可以使用自己的指纹为群组匿名生成随机字符串，并可以在需要时进行跟踪，而其他成员可以使用他们自己的指纹复制字符串。此外，可以重复使用指纹来生成多个随机字符串。基于RGFE，我们提出了一个群组共享比特币钱包，该钱包可以由一组用户通过生物识别技术以可追踪的方式接收或消费硬币。

Reusable Group Fuzzy Extractor and Group-Shared Bitcoin Wallet

In this paper, we propose a novel cryptographic primitive named reusable group fuzzy extractor (RGFE) allowing any member of a group to extract and reproduce random strings from a fuzzy and non-uniform source of high entropy (called fingerprint). Any group member can anonymously generate a random string for the group using his fingerprint and can be traced when needed, whereas other members can reproduce the string using their own fingerprints. Moreover, a fingerprint can be repeatedly used to generate multiple random strings. Basing on RGFE, we present group-shared Bitcoin wallet, which can be used by a group of users to receive or spend coins via biometrics in a traceable way.
