Abstract:
A printer includes a memory to store a one-time pad, and a request module to send a request to a remote server for one-time pad key material. The printer further includes a refresh module to decode encoded one-time pad key material contained in a physical document generated by the remote server in response to the request, and update the one-time pad with the decoded one-time pad key material.
