云数据生命周期安全性问题及加密技术研究

Cloud Data Lifecycle Security Issues and Encryption Technology Research

摘要: 随着云计算的深入发展，越来越多的企业和个人都利用云平台来存储数据以及进行相关数据的处理，将数据上传到云服务器，由云服务器进行储存和管理。然而，随着用户以及云服务商的增多，越来越多的云服务商出现数据泄露的情况，云计算的安全问题也日渐突出。在数据存储、数据传输和数据销毁的过程中，数据极易出现被盗取后非法使用及无法删除数据的情况，对数据产生极大的威胁。本文将针对云计算中数据的安全性进行研究，在分析云计算发展现状及云计算主要技术的基础上对云环境下的数据传输安全进行讨论，并提出相应的解决措施，以保证云计算中数据传输的安全性。

Abstract: With the development of cloud computing, more and more enterprises and individuals are using the cloud platform to store data and deal with the relevant data. The data is uploaded to the cloud server and stord and managed by the cloud server. However, with the increase in users and cloud service providers, more and more cloud service providers appear the situation data leakage; cloud computing security issues have become increasingly prominent. The data is uploaded to the cloud server until the data is definitely deleted. In the process of data storage, data transmission and data destruction, the data is easily stolen and illegally used, and it can not be deleted; the data generated a great threat. This paper will study the security of data in cloud computing, discuss the data transmission security in cloud environment on the basis of analyzing the current situation of cloud computing and the main technology of cloud computing, and put forward the corresponding measures to ensure the data transmission security in cloud computing.
