Jie Ling · Jisuanji gongcheng yu sheji · 2013
Aimed at the security issues such as data leakage and data tampering in cloud storage technology,combined with the characteristics of HDFS data integrity verification mechanism,a kind of data security technical solution is designed and implemented,which is based on data transmission and data storage of HDFS.The data uploaded to HDFS is encrypted by AES algorithm and stored in cipher,and the AES secret key is encrypted by RSA algorithm.This solution can effectively avoid the leakage of data transmission and storage.The file stored in two kinds of form,cipher-form and plaintext-form.The user can choose either one to encrypt the file.On the basis of the security analysis and experimental data of the performance test,the security and viability of this solution are verified.
