As the cloud has grown rapidly, people have been more concerned about their data security. In order to overcome the problem of difficulty in the algorithm combination selection in the secondary hybrid encryption algorithm of cloud storage, the common six symmetric encryption algorithms and two asymmetric encryption algorithms are combined in this paper, we measure the value of encryption algorithms in three ways: the speed of encryption, the level of security, and the sensitivity to plaintext. Finally, the algorithm combination of 3DES algorithm and RSA algorithm was selected by K-means clustering algorithm, which improved the encryption speed on the basis of guaranteeing security.
