A Providing Security on Cloud Data Hadoop using Symmetric Encryption and Identity Authentication

Cloud computing is evolving as a much known data interactive paradigm to realize users data remotely stored in an online cloud server. - Security of distributed network is very important part in todays era. In order to solve the existing security problem of the distributed network cloud disk, such as transmission, storage security problems, etc. , a network cloud disk safety storage scheme based on Hadoop is proposed. Based on the different confidential level of user data, it gives selective encryption scheme, which gives full consideration to the following security issues, such as the security of the user data transmission in the network, user data no verification, the user data privacy might be leaked, etc. Combined with the rapid encryption of symmetric encryption algorithm like Blowfish and identity authentication of RSA, overtime checking and the performance of Hadoop, the distributed network cloud data security storage disk can supply secured, effective, stable effect.
