摘要
越来越多的数据存储工作都实现了远程资源访问。在云环境中,用户无法确认任务实际运行的物理运行环境,这就无法保证远程资源的安全性和可信性。解决这个问题的方案之一就是对加密后的用户数据进行运算,取代明文操作。这样用户就可以生成由第三方执行的程序,只需要操作密文而不需要对明文运算。这就确保了应用程序和数据在云环境传输中的安全性。本文提出了利用同态加密技术应用于云环境的数据传输,提高云环境中数据传输的可靠性与安全性。
More and more data storage work to achieve remote access to resources.In the cloud environment,the user is unable to confirm the actual task of running the physical operating environment,which cannot guarantee the security and credibility of the remote resources.Program to solve this problem is encrypted user data operations,replaced plain-text operations.So that users can be generated by a third party implementation of the program,only need to manipulate the cipher-text without the need to plain-text computing.This ensures the security of applications and data in the cloud environment.In this paper,homomorphic encryption technology used in data transmission of the cloud environment,improve the reliability and security of data transmission in the cloud environment.
