We address the problem of using an untrusted server with only a trusted timestamping device (TTD) to provide trusted storage for a large number of clients, where each client may own and use several different devices that may be offline at different times and may not be able to communicate with each other except through the untrusted server (over an untrusted network). We show how a TTD can be implemented using currently available Trusted Plat
