摘要
在数字化时代,信息技术的迅猛发展推动了各个领域的数字化转型,数字化管理平台在企业经济发展中的重要性日益凸显。为此,研究对数字化管理平台访问控制与数据共享过程进行了分析,提出了基于Paillier密码机制的访问控制模型和基于区块链的数据共享模型。结果表明,当中继节点的数量从5增加到10时,模型的密钥生成时间从2.01 s增加至了3.23 s,解密时间从8.86 ms增加至14.94 ms。当属性数量为0-50时,所提访问控制模型的加密时间在0-30 ms区间。当属性数量为50时,所提模型的解密时间为4.9 ms,加密时间为1.22 s。实验结果证明了所提模型的有效性和运行效率,将其运用在企业的数字化管理平台中,有助于引导企业向数据驱动的经营模式转型,推动产业的数字化转型和经济的高质量发展。
In the digital age,the rapid development of information technology has driven digital transformation in various fields,and the importance of digital management platforms in enterprise economic development is increasingly prominent.Therefore,the study analyzed the access control and data sharing process of digital management platforms,and proposed an access control model based on Paillier cryptographic mechanism and a data sharing model based on blockchain.The results showed that as the number of relay nodes increased from 5 to 10,the key generation time of the model increased from 2.01 s to 3.23 s,and the decryption time increased from 8.86 ms to 14.94 ms.When the number of attributes is 0-50,the encryption time of the proposed access control model is in the range of 0-30 ms.When the number of attributes is 50,the decryption time of the proposed model is 4.9 ms and the encryption time is 1.22 s.The experimental results have demonstrated the effectiveness and operational efficiency of the proposed model.Applying it to the digital management platform of enterprises can help guide the transformation of enterprises towards data-driven business models,promote the digital transformation of industries,and promote high-quality economic development.
