Abstract: Systems and methods enable members of a secure transaction network to readily identify the appropriate trusted service manager (TSM) to support a particular transaction. A global directory of TSM providers is provided that a secure service provider can use for determining which TSM provider is the authorized manager of a security domain for the particular transaction. In aspect the directory of TSM providers may be stored within a mobile device secure element. In another aspect, the directory of TSM providers may be stored in a central TSM repository. In a further aspect, the directory of TSM providers may be distributed among a number of secondary TSM repositories. The appropriate TSM may be identified based upon a secure element identifier and an application identifier provided by a secure element as part of the transaction. Communication of the identifiers from mobile devices may be via cellular or near field communication links.
