Enabling cloud storage security based on rate less codes

摘要

As the cloud storage is becoming center part for storing data remotely, user no longer store his data in local depository and user can access data from anywhere. Mostly the users store their data to public cloud, it reduces the storage management of data locally. But there are also security issues such as confidentiality, integrity and availability. Shen et al. [6] has proposed an effective integrity verification scheme for secure erasure code based storage system. As the public cloud is untrustworthy we cannot be reliable on cloud server for encoding the data and keeping in the cloud. In this paper, we propose a new approach based on rate less codes. Our scheme uses proxy server for encoding the cipher text using rate less codes, OFG algorithm for decoding and TPA is used for checking the integrity of data. The analysis shows that our secure cloud storage scheme has better data integrity, availability and confidentiality.
