When the current method protects the data of cloud computing users,the data input and output are defined by a uni-fied function,which cannot ensure the diversity description of each attack,leading to the low security coefficient of cloud comput-ing user data.In this regard,the improved encryption algorithm is introduced to carry out the research on the data security protec-tion 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 experi-ments,it is proved that the new protection method can deal with a variety of cloud computing user data attacks,protect the data se-curity,and improve the data security coefficient.
