Full fail-stop property

In this subsection, a weaker version of the fail-stop property is explained. In the notation of Section 5.2.3, it yields a signature-like scheme with accountable centres. Such schemes are called fail-stop signature schemes with special risk hearers. Where a distinction is necessary, the real signature schemes with a fail-stop property as described above are called full fail-stop signature schemes, and their property a full fail-stop property. 

Thus the full fail-stop property is one where everybody is regarded as a risk bearer (except that they do not have special access points for their role as risk bearers then). The full fail-stop property is useful, for instance, if one wants unforgeability in the original sense, or if the system is completely stopped once the output broken occurs and everybody considers this a nuisance.
