Circuit Copyright Blockchain: Blockchain-based Homomorphic Encryption for IP Circuit Protection

摘要: The fast development of Blockchain technology makes it widely applied in several fields digital transactions, like e-government affairs and the protection financial transactions. In this paper, we propose a homomorphic encryption-based for circuit copyright that effectively addresses issues such as low security private data efficiency transaction storage, cooperation supervision. First, establish mathematical model by utilizing intelligent contract, next, algorithms include generation, chain encryption/decryption, contract are designed. As is correctly executed Blockchain, fully identity authentication protocol tackled given ensures change operation any third-party realizes real-time verification. system apposite blockchain network, due to use distributed extensible storage improves extensibility blockchain-based protection. experimental results show proposed algorithm has reduced transmission cost improved
