Any alternative definition or concept to cover what protocol designers usually refer to as non-repudiation specifications? For example non-repudiation of origin, i.e. the ability of recipient to convince a third party that a message was sent (to him) by a particular sender (at certain time)?

Or - do you think this is not an important requirement?
Or what?
