一种用户隐私保护数字货币的可监管方案

doi:10.19665/j.issn1001-2400.2020.05.006

Abstract

Abstract:

The regulation of digital currency is currently a hot topic. At present, there are some digital currencies that protect user privacy well, but are unable to be regulated, which hinders the further application of these digital currencies. By taking Monero as an example, this paper proposes an improved solution based on a group signature and a knowledge proof for CryptoNote, the underlying technology of Monero, which can achieve the regulation of Monero. The group manager can trace a suspected transaction, determine the real identity of its sender, find the complete transaction list of the sender, and revoke the private key to freeze the coins of the sender when necessary.

Key words: digital currency, group signature, regulation, privacy protection
