区块链技术的快速发展使其广泛应用于数字交易的多个领域，如电子政务和金融交易的保护。在本文中，我们提出了一种基于同态映射的电路版权保护区块链，有效地解决了电路版权交易保护中的问题，如私有数据安全性低，交易数据存储，合作和监管效率低。首先利用区块链和智能合约建立了基于同态映射的数学模型，然后设计了区块链生成、同态链加解密和智能合约等算法。由于智能合约在区块链中的正确执行，因此为区块链解决了一个基于全同态验证的身份认证协议，该协议确保了区块链中任何第三方的更改操作，并实现了实时验证。该系统适用于区块链网络中的电路版权保护，由于分布式身份认证和实时可扩展存储的使用，提高了基于区块链的电路版权保护的安全性和可扩展性。实验结果表明，该算法降低了传输开销，提高了数据存储和监控效率。此外，它对几种常见的攻击（例如，双重花费攻击），但与其他三种竞争算法相比，其成本/开销较低，并且具有更高的安全级别。
The fast development of Blockchain technology makes it widely applied in several fields of digital transactions, like e-government affairs and the protection of financial transactions. In this article, we propose a homomorphic encryption-based Blockchain for circuit copyright protection that effectively addresses the issues in the protection of circuit copyright transactions, such as low security of private data, low efficiency in transaction data storage, cooperation and supervision. First, we establish a homomorphic encryption-based mathematical model by utilizing Blockchain and intelligent contract, and next, the algorithms that include Blockchain generation, homomorphic chain encryption/decryption, and intelligent contract are designed. As the intelligent contract is correctly executed in Blockchain, a fully homomorphic encryption-based identity authentication protocol is tackled for Blockchain, given that it ensures the change operation of any third-party in Blockchain and realizes real-time verification. The system is apposite for circuit copyright protection in a blockchain network, due to the use of distributed identity authentication and real-time extensible storage improves the security and extensibility of blockchain-based circuit copyright protection. The experimental results show that the proposed algorithm has reduced the transmission cost and improved the efficiency of data storage and supervision. In addition, it is resilient to several common attacks (e.g., double-spending attacks), yet incurs low cost/overhead and has a higher level of security when compared to three other competing algorithms.
