Abstract

In the block chain privacy protection technology, the decentralized coin mixing mechanism, CoinJoin and CoinShuffle, has the problem of low security or efficiency because the agent node cannot be trusted and the node need to pass encryption layer by layer, respectively. Therefore, this paper proposed TTShuffle, a two-tier privacy protection mechanism. Firstly, it divided all mixed currency nodes into different groups, and shuffled the first layer in the group through layers of encryption to protect the sensitive data of intra-group transactions; Then, each group sent a node as the representative of the group, and carried out the second layer of inter-group shuffling to protect the sensitive data of all groups to obtain the final complete transaction content. Through security and experimental analysis, it shows that the mixing time of the 40 participants in TTShuffle is less than 10 s, which improves the mixing efficiency, reduces the mixing time and ensures the privacy security of the mixing process compared with the CoinShuffle mechanism.
