DIGITAL SIGNATURE DELEGATION

摘要

A method intended to be implemented by an intermediate server device (SLI), comprising the steps consisting in: receiving a file (GL) from a signatory device (SL) and a signature (s) of said file by said signatory device, modifying the file received, determining signature data (s, r) in such a way that a destination device (T) recognizes the modified file as signed by the signatory device, and dispatching the modified file (L) and the signature data to the destination device.
