基于ECC的区块链数据共享系统设计

A blockchain data sharing system based on ECC

区块链技术通过在对等网络环境下构建不可伪造、不可篡改和可追溯的链式数据结构的模式,解决了传统数据共享所存在的数据泄露、数据篡改和数据难溯源等问题。然而现存的区块链数据共享方案还存在成本高、效率低和安全性差等问题,对此提出了一个基于椭圆曲线加密算法ECC的区块链数据共享方案并进行了系统设计。该方案依靠ECC算法来保证数据传输过程的安全性,改善现有方案所存在的问题。利用Solidity编程语言编写对应的智能合约,基于以太坊平台对数据共享系统进行了仿真和测试,验证了方案的正确性和安全性。

Blockchain technology can solve the problems of data leakage,data tampering,and difficult data traceability that exist in traditional data sharing by constructing an unforgeable,non-tamperable and traceable chain data structure model in a peer-to-peer network environment.However,the existing blockchain data sharing so-lutions also have problems such as high cost,low efficiency,and poor security.Aiming at these issues,a blockchain data sharing scheme based on elliptic curve cryptography(ECC) is proposed and the system is designed.The program relies on ECC to ensure the security of the data transmission process and improve the problems in the existing program.The corresponding smart contract was written by the Solidity programming language,and the data sharing system was simulated and tested based on the Ethereum platform.
