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.
