The invention provides a grouped multiple-key encryption method and a grouped multiple-key encryption device. A plurality of groups of different keys are generated, to-be-encrypted data is grouped and encryption and secondary encryption are carried out on the to-be-encrypted data with the use of the plurality of groups of different keys, thus greatly improving the security of the keys and the security of encrypted files. By the adoption of a multiple-key data-grouping encryption mechanism, the problem that all data is insecure once a key is acquired for an existing single-key encryption method is solved. As different keys are used, different encrypted data is generated after data of the same content is encrypted, thus solving the hidden safety problems of an ECB model. As an ECB model is adopted among blocks and encryption blocks are independent of each other, only data of the damaged blocks is affected and other data is not affected at all even if the encrypted data is damaged, which is conducive to data recovery and reduces the loss caused by data damage.
