Abstract

A system for collaborative document generation comprrsrng: a document management server (102) adapted to manage document storage (101) and having an associated pair of signing and verification keys; at least two clients (104) each having a unique identifier and a pair of signing and verification keys, said verification keys of said clients being available to said document management server and to other clients; a document management module (103) adapted to receive service requests from said clients; an aggregate signature module (105) residing in said document management server; and digital signature modules (106) residing in each of said clients; wherein said aggregate signature module is adapted to sign messages using the document management server signing key by verifying signatures on messages given a signature, verification key and message; aggregating a set of signatures to produce an aggregate signature; and verifying said aggregate signature given said aggregate signature, a set of associated verification keys and a set of associated messages; and wherein said digital signature modules are adapted to: sign messages using the respective client signing keys; verify signatures and messages given a signature, verification key and message; and verify said aggregate signature given said aggregate signature, a set of associated verification keys and a set of associated messages. The most illustrative drawing is FIG. 1.0.
