In recent years, cryptocurrencies (crypto-assets) such as Bitcoin, Ethereum, and NEM have attracted attention in various aspects, such as the large market capitalization and the use of smart contracts. On the other hand, it has been used for crimes due to their anonymity and it becomes a target of cyber attacks as their value increases. Sato et al. (CSS2019, SCIS2020) proposed a method of giving anonymous token on Blockchain system, which has audit function, by accountable ring signature, and confirmed that their method is applicable to Bitcoin and Ethereum. In this paper, we confirm that Sato et al.'s method is also applicable to NEM. |
