摘　　要：传统的数据共享平台通过单一框架策略对数据传输的安全性进行保护,但数据传输速度较慢,且有泄露的风险,难以满足当前的创新创业数据共享需求。针对传统数据传输策略存在的不足,基于区块链技术搭建了双创数据共享平台。在数据加解密模块中,对非对称加密算法RSA加以改进,构建了DES-RSA混合加密算法,使其在提高处理速度的同时还兼顾了综合性能。同时通过采用三数据广播的方式对数据进行防篡改保护,从而可避免因密钥泄露而导致的恶意篡改。数据封装完毕后,应用PBFT共识机制保证了局域网环境下数据传输的鲁棒性。实验测试结果表明,所设计的加解密算法性能较为理想,数据防篡改率可达99.9%以上,且数据传输鲁棒性、可靠性也较高。The traditional data sharing platform protects the security of data transmission through a single framework strategy.The data transmission speed is slow and there is a security risk of leakage,which is difficult to meet the current needs of innovation and entrepreneurship data sharing.Aiming at the shortcomings of traditional data transmission strategies,this paper builds an innovation and entrepreneurship data sharing platform based on blockchain technology.In the data encryption and decryption module,the asymmetric encryption algorithm RSA is improved,and the DES-RSA hybrid encryption algorithm is constructed to improve the processing speed and take into account the comprehensive performance.At the same time,the data is protected against tampering by means of three data broadcasting to avoid malicious tampering caused by key leakage.After data encapsulation,PBFT consensus mechanism is applied to ensure the robustness of data transmission in LAN environment.The experimental results show that the encryption and decryption algorithm designed in this paper has ideal performance,the data tamper proof rate can reach more than 99.9%,and the data transmission has good robustness and high reliability.
