【摘要】 云计算的一个重要应用是处理大数据,其中云存储就是在线上处理数据为各类商家服务的.这就涉及到数据的保密性和安全性,同时还有数据上传和下载的速度和实时性.速度和实时性依赖与通讯商的带宽等硬件设备,数据的保密性和安全性往往依赖与现有的各种密码技术,因此云存储技术的关键是构建一种安全可靠的云存储平台.本文探讨一种优化的RSA密码技术,加载随机预言模型后,构建一种安全的云存储平台,对客户在上传和下载过程中进行快速加密和解密,保障数据的安全性,为云服务商提供更大的盈利空间,具有较大的经济和实用价值.更多还原

【Abstract】 Cloud computing is an important application to deal with big data. Among which,cloud storage is the online processing of data for all kinds of business services. This involves the confidentiality and security of the data,as well as data upload and download speed and real-time. Dependence of speed and real-time performance and the bandwidth of the communication business hardware equipment, data confidentiality and security often rely on and the various existing password technology, so the cloud storage technology, the key is to build a safe and reliable cloud storage platform. The objective of this paper is to discuss an optimization of the RSA cryptography, after loading the random oracle model to construct a secure cloud storage platform,to customers in the upload and download process of fast encryption and decryption,guarantee the data security,to cloud service providers provide greater profit space,with great economic and practical value.更多还原
