Improving Reliability and Security in Multi-Cloud Environment using Two Layer Encryption

  • Dr. K Suresh, V Kavitha


Cloud computing is the next generation of enterprise IT architecture. It allows sharing of software applications and database data for most - major centers for data, each in the middle, because such data is stored in the cloud, there is an important factor of security and confidentiality. Therefore, the study of this problem is addressed in the proposed system, which has a two-layer encryption for securing of confidentiality of data. Encryption of the outer layer is carried out by the cloud side, and the internal encryption  of the owner of the data. Encrypted files not be stored directly, they will be stored in various database data on the location of the server, which makes security and availability of data together.
