Re-Encryption Scheme to Provide Secure Data Forwarding in Cloud Storage System
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 30, Vol 3, Issue 11
Abstract
A cloud storage system is considered as a large scale distributed storage system which consists of several independent storage servers. In Cloud computing the resources on the Internet are considered and managed as a combined entity called cloud. Data stored in the third party cloud system might create serious concern on data confidentiality. To provide strong confidentiality for messages and information in storage servers, the user can encrypt messages by a cryptographic method. Most conventional encryption schemes protect data confidentiality but also limit the functionality of the storage system as only few operations are supported over encrypted data. In this paper, the authors discussed about the problem of forwarding data to another user by storage servers directly under the command of data owner. To provide a secured data forwarding, we propose a proxy re-encryption scheme and integrate it with a secured decentralized code to form secure distributed storage system. The constricted integration of encoding, encryption and data forwarding build the storage system efficiently and effectively meet the specifications of data robustness, data confidentiality, and data forwarding.
