Verification scheme of retrievability supporting XOR rotated erasure codes for cloud storage data
云存储中支持XOR旋转编码的可恢复性验证方案

To improve fault tolerance and reliability of cloud storage data, a verification scheme of retrievability is designed for cloud storage encoded files. In the scheme, a present rotated RS code named XOR rotated code is improved, and a verification method is proposed, which can perform the tags of column vectors of coding matrix with fast module multiplication. Performance evaluation and security analysis show it has a lower computational cost and communication cost and more efficient data recovery guarantee.
