In view of the security problems such as data leakage and data tampering in cloud storage technology, combining the characteristics of HDFS data integrity checking mechanism, a HDFS based storage security technology scheme is designed and implemented. To the user uploaded to the HDFS data file implementation of AES encryption, files in ciphertext form storage, and the application of RSA algorithm to protect the encryption of AES key, can effectively prevent the data in the transmission and storage process is leaked. The paper designs two kinds of storage formats, which are based on HDFs file cipher text and file plaintext, and the user can choose whether or not to encrypt. Through the security analysis and the performance test, the security and feasibility of the scheme are validated.
