基于改进加密算法的云计算用户数据安全保护方法

Data security protection method of cloud computing users based on improved encryption algorithm

当前方法对云计算用户数据保护时,以统一函数定义数据输入和输出,无法确保针对每种攻击的多样性描述,导致云计算用户数据安全性系数低的问题。对此,引入改进加密算法,开展云计算用户数据安全保护方法研究。利用改进加密算法,对用户身份认证;利用多个函数,定义输入和输出,实现云计算用户可验证静态数据存储;优化并合理限制Privilege Closure执行,实现云计算用户动态数据安全保护。对比实验证明:新的保护方法可以应对多种云计算用户数据攻击,保护数据安全,提高数据安全性系数。

When the current method protects the data of cloud computing users,the data input and output are defined by a unified function,which cannot ensure the diversity description of each attack,leading to the low security coefficient of cloud computing user data.In this regard,the improved encryption algorithm is introduced to carry out the research on the data security protection method of cloud computing users.Using improved encryption algorithm to provide user identity authentication;using multiple functions to define input and output to realize stable static data storage for cloud computing users;optimize and reasonably limit Privilege Closure execution to realize dynamic data security protection for cloud computing users.Through comparative experiments,it is proved that the new protection method can deal with a variety of cloud computing user data attacks,protect the data security,and improve the data security coefficient.
