data analysis processing method and device based on memory encryption and decryption

The invention discloses a data analysis processing method and device based on memory encryption and decryption, and the method comprises the following steps: enabling an encryption algorithm to be associated with a data model, and defining the encryption algorithm and the data model as a security strategy; storing the security policy in a database; Acquiring the security policy; and calling a decryption algorithm in the security policy to decrypt and desensitize the data model. The beneficial effects of the invention are as follows: the paint has good effects; According to the scheme, the analysis processing of the encrypted data is converted into security policy management; the security policy is embedded into a database; the non-perceptual structured encrypted data analysis processing isrealized; On the basis of an original standard sql business process, an operator and a developer can directly develop a corresponding sql script to decrypt and desensitize the data model without adding a manual process to de
