description The invention belongs to the technical field of cloud storage security, and discloses a storage proving method for rapid positioning and recovery of an invalid file of a dynamic group user, and the storage proving method for providing the rapid positioning and recovery of the invalid file for the dynamic group user comprises the following steps: generating a corresponding signature key according to a key generation protocol; performing RS (Reed-Solomon) coding on a file, and signing the coded data to generate a corresponding data label; performing integrity auditing on the data according to the bilinear mapping; and if the auditing fails, quickly positioning and effectively recovering the failure data according to the CIRG scheme provided by the invention; finally, analzying the security and correctness of the scheme, and proving that the scheme is safe for the dynamic group users. According to the scheme of the invention, the application of the dynamic group users in the cloud storage is more convenient, saf
