Non Repudiation

[Arvola Chan <arvola@tibco.com>]

Don't non repudiation of origin and non repudiation of receipt imply that the recipient has to keep a persistent copy of the message for some rather long period of time (typically of the order of years)?

 

Is this duration implicit (i.e., has the same value for all cases) or should it be represented explicitly in the CPA?

 

Another related question is whether the logging functionality to support non repudiation belongs above or below the Message Service Interface.
