TS1 = TimeStamp(h7)

ArchiSoft generates Evidence Records
ArchiSoft works with every DMS

TASP = Trusted Archive Service Protocol (simplicity!)
TSP = Time Stamp Protocol (RFC 3161)
JDBC = Java Database Connectivity
DB = Data base of DMS
Fundamentals:
• DMS client is not modified• DMS server sends ONE
message to ArchiSoft: „please notice: there is a new document“
• The DMS asks for the document when ArchiSoft builds the hash tree
• The DMS can „forget“ any problems of signature renewal, because everything is managed by ArchiSoft
• The document can be verified any time in future
