Private and secure communications can be vital for certain applications, for example secure bidding, e-commerce, and online bank transactions. However, it is impossible to carry out private conversations in the open tuple-space model, despite it being a popular coordination model for distributed, heterogeneous systems, where agents can communicate via a common data space without having to know each other’s identity, or having to arrange for a definite rendezvous. In this paper, we present an algorithm for establishing private communications in tuple-space systems using capabilities. In view of the fact that open systems need to be scalable, capa-bilities may provide a finer control to the loose control coordination of tuple-space systems whilst maintaining their flexibility. As capabilities can only refer to uniquely identifiable objects, we have introduced the concept of em multicapabilities---capabilities for groups of unnamed objects---to be applied to nameless tuples.
