Abstract

Workﬂow Management (WFM) Systems automate traditional processes where information ﬂows between individuals. WFM systems have two major implications for security. Firstly, since the description of a workﬂow process explicitly states when which function is to be performed by whom, security speciﬁcations may be automatically derived from such descriptions. Secondly, the derived security speciﬁcations have to be enforced. This paper considers these issues for a Cyberspace workﬂow system by describing a small, but comprehensive example.

The notion of an Alter-ego is central in this description: Alter-egos are objects that represent individuals in Cyberspace (and not merely identify them). In Cyberspace, documents in a workﬂow system therefore ﬂow between Alter-egos, rather than between individuals.
