摘要
本文针对云计算环境下数据委托存储所面临的安全问题进行了研究和探讨,提出了一种基于身份的委托加密方案。该方案将消耗资源的公钥加密运算委托给云端节点执行,减轻了用户节点的计算负担,同时采用数据盲化技术确保第三方无法获取敏感数据。该方案可以解决特定场景下的数据安全存储问题。
This paper researches and discusses the security issues associated with delegated data storage in cloud computing environments.A delegation encryption scheme based on identity-based public key cryptography is proposed to solve this problem.The scheme delegates resource-consuming public key encryption computations to cloud nodes to reduce the computational burden of user nodes.Additionally,data blinding techniques are used to ensure that third parties cannot access sensitive information.Through the analysis of the security and characteristics of the proposed scheme,it is demonstrated that this scheme can solve the problem of data security storage in specific scenarios.
