Patent

CA 2665445

Systems, devices, and methods for modifying a signed bundle and verifying the modified bundle are disclosed. A signed bundle may be modified by removing a file specified in a server file list from a plurality of files in the bundle. The signed bundle comprises a catalog of files in the signed bundle and their associated hashes. The modified bundle includes the remaining files of the signed bundle that are not specified in the server file list and the catalog file of the signed bundle, the catalog signature of the signed bundle. The modified bundle may be verified by verifying the catalog signature of the modified signed bundle, and checking that the files specified in the catalog are either in the modified signed bundle or specified in the server file list. The hashes of the files in the modified signed bundle may also be checked to verify the modified signed bundle.
