Abstract
By accepting a shared secret or shared control scheme specified by an access structure Γ, an issuing authority also implicitly accepts all of the access structures that can be realized as a result of trust relations that may exist among some of the participants in Γ. An algorithm is presented here that makes it possible to fully analyze the consequences of trust to such schemes.
