摘要
随着互联网的发展,云计算模式能够提供便捷的、可用的和按需要网络资源,云计算的核心是如何存储和管理用户的数据,除了配置存储设备的之外,还要考虑到存储在云中的数据的安全性。RSA加密算法是基于一个比较简单的数论—两个大素数相乘十分容易实现,但要对它的乘积进行因式分解却十分困难,RSA加密算法是将乘积公开作为加密密钥的非对称加密方法,在云计算中应用RSA算法对存储在云中的数据进行加密,能够保证了数据的安全性。
With the development of the Internet, cloud computing can provide convenient and available network resources, the core of cloud computing is how to store and manage user data, cloud computing does not provide storage devices, but also takes into account the security of the data stored in the cloud. RSA encryption algorithm is based on a relatively simple theory of math- multiplying two large prime numbers is very easy to achieve, but it's the factorization is very difficult, RSA encryption algorithm considers a product as a public encryption key and is an asymmetric encryption method. To ensure the security of the data, RSA encryption algorithm is applied for the data storage in the cloud.
