interesting question presumably there would have to be a time stamp as part of the sig which if it was too old then the message would get discarded you would have to hash the time as otherwise it would be open to spoofing think kerberos has this facitlity but it tends to be **MUCH** tighter (matter of mins by default to allow for slew) and is used to stop replay attacks full-disclosure-admin () lists netsys com wrote on 19/11/2004 07:39:19:
