| description | The invention discloses an electronic file front-end control method based on proxy re-signature. The invention relates to the field of computer science and archive management. The method comprises thesteps of system initialization, generation of a user id private key skid in the system, signature of an electronic file m by an electronic file generator A, generation of an electronic file m re-signature secret key rkA-B, verification of an electronic file m re-signature SigB by an archive manager B and verification of the electronic file m re-signature SigB. When the electronic file is generated, an archive manager intervenes in advance and manages the electronic file before the electronic file is handed over; after an electronic file generator digitally signs the electronic file, when theauthenticity and integrity of the electronic file need to be verified, the electronic file is realized by verifying the digital signature; when the electronic file is handed over to a file manager, the file manager uses a re-s |
