Problems solved by technology

But on the other hand, for the application of blockchain in society, the difficulty of supervision has become a common concern of various countries
Existing literature only focuses on how to better protect the privacy of blockchain users, but few people pay attention to how to supervise illegal transactions using blockchain

Embodiment Construction

[0029] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0030] Such as figure 1 As shown, the blockchain illegal address supervision system based on group signature in this embodiment is as follows:

[0031] The system includes users, miners, regulators and alliance chain network;

[0032] The user conducts transactions or data sharing on the alliance chain network platform;

[0033] The users mentioned above must register with the regulator before they settle in, in order to carry out effective transactions.

[0034] The miners are elected from the users by the consensus algorithm and are responsible for checking the legitimacy of each user's transaction;

[0035] The existing mainstream consensus algorithms are POW (Proof...

Abstract

The invention discloses a block chain illegal address supervision system and tracing method based on group signature. The system comprises a user, a miner, a supervisor and an alliance chain network. The system is used for tracing illegal addresses, and the method is divided into a registration stage, a transaction stage and a tracing stage. In the registration stage, a user registers to generate a private key and a public key, and a supervisor allocates a voucher to the user; in the transaction stage, a transaction initiator generates an ECDSA signature, a transaction receiver signs a tracing signature, the two signatures are verified by an absenteeter, and when the verification is not passed, it is determined that the transaction is illegal and traced; in the tracing stage, the supervisor checks the transaction time, locks the transaction on the alliance chain network platform, and traces the real identity corresponding to the transaction address. According to the invention, on the premise of not influencing normal transactions, a supervisor can effectively trace the identity corresponding to the illegal transaction address, so that the safe operation of the whole system is ensured.

Description

technical field [0001] The invention relates to the technical field of information security, in particular to a group signature-based blockchain illegal address supervision system and a tracing method. Background technique [0002] Since the birth of blockchain technology, it has attracted widespread attention from the society. Based on the theory of cryptography, blockchain technology is applied to various fields with decentralization, non-tamperability and anonymity, such as anonymous voting by departments, financial and aerospace data sharing and so on. The anonymity of the blockchain has always been a very controversial topic. The blockchain can be used as a platform for digital currencies, such as Bitcoin and Ethereum. Transactions between currencies are anonymous, which makes it possible to see from the blockchain ledger The identities of the parties to the monetary transaction are not included. The blockchain can also be used as a platform for data sharing or collab...
