A Secure Erasure Code-Based Multi Cloud Architecture with Privacy and Preservation

Kousalya.K, Nagajothi.A

Cloud storage architecture will have a collection of storage servers with higher end configuration which will provides long-term storage services over the Internet and also for the cloud storage system. Here storing and retrieving the data in a third party’s cloud system causes serious problems and conflict over data confidentiality during the data transactions. Whenever third party storage will involved with the multi cloud server this conflict will occur naturally. But general encryption processor and verifier schemes protect data confidentiality during the transaction of dual execution. In this paper, we propose a secured threshold proxy re-encryption server and integrate it with a decentralized erasure code such that a secure distributed storage system is formulated. The main technical contribution is that the proxy re-encryption scheme supports encoding operations along with a key over encrypted messages and forwarding operations over encoded and encrypted messages. This method is implemented for secured data forwarding. During data forwarding a proxy server will be created virtually to access the encrypted data from the sender side. This makes less traffic and the original data content will not get affected during the time of data transaction. After the transaction the proxy server will be deleted.
