Description
Summary:In the application of cloud storage, user file is not in local storage, therefore, file security, data confidentiality, and robustness are the key problems. First, aimed at the secure erasure code storage system of several key servers proposed by existing literatures, the problem that data robustness leads to defects in data recovery is not considered, and the end-to-end checking strategy threat model of cloud storage is established by using pseudo-random linear mapping; second, interface file block structure is prepared and integrity check project design is conducted by referring to relevant literature algorithm to realize the supplement of secure erasure code storage system algorithm function of multiple key servers and provide the analysis of calculation complexity of algorithm; at last, the experiment result shows that the proposed integrity check program can realize greater successful retrieval probability of data.
