Abstract
A method for integrity auditing is provided. The method comprises: generate a challenge message for verifying data integrity of a file stored at a storage server (); send the challenge message to the storage server (); receive, from the storage server, a proof on the data integrity of the file, the proof being generated based on the challenge message (); verify the data integrity of the file by verifying validity of the proof (). In this way, integrity auditing for multi-copy storage can be enabled, where the overhead in updating data is independent of the number of copies of the data.
