Abstract

The invention provides a Bitcoin hidden service node transaction tracing method. The Bitcoin hidden service node transaction tracing method comprises the following steps: S1, position tracing of Bitcoin hidden service node: establishing a hidden channel between a controlled guard node and a collusion Bitcoin monitoring node by using a Bitcoin heartbeat mechanism, and designing a signal coding mode, so that position tracing of the hidden Bitcoin node is realized; and S2, transaction tracing of the Bitcoin hidden service node: controlling a delay strategy of transaction receiving and forwarding of the hidden Bitcoin node at the controlled guard node to realize the transaction tracing of the hidden Bitcoin node. According to the Bitcoin hidden service node transaction tracing method provided by the invention, the new Bitcoin transaction tracing method can identify transactions created by a target Bitcoin hidden service node with relatively high accuracy and recall rate, so that a new tracing problem caused by supporting Tor by Bitcoin is solved to a certain extent, and it is proved that the Tor network cannot well protect the privacy of Bitcoin users.

Description

technical field [0001] The invention relates to the technical field of privacy protection in network security, in particular to a method for tracing the source of Bitcoin hidden service node transactions. Background technique [0002] Cryptocurrency is based on the principles of cryptography and uses blockchain technology to ensure decentralization through a distributed consensus mechanism. The typical representative is Bitcoin. The transaction data of Bitcoin is public on the entire network, but its address is only Each string generated based on an asymmetric encryption algorithm has no direct relationship with the user's real identity, and a user can create countless addresses, and there is no direct relationship between these addresses. From this level, Bitcoin provides a certain of anonymity. [0003] The transaction traceability of Bitcoin can usually be started from three aspects, the network layer, the data layer and the application layer. The goal of network layer ...
