Abstract

Trust is established between a service provider (20) and a client (10) of the service provider (20). The client (10) is associated with a party that is known by an identity provider (50), and the identity provider (50) is trusted by the service provider (20). The identity provider (50) contacts (70) the party (80) via a predetermined medium, and requests the party to identify itself. The identity provider (50) determines whether the identity of the identifying party (80) corresponds to an identity held by the identity provider (50) for the party and shares a secret (100) with the identifying party (80) in the event that the identity provider (50) has determined that the identity of the identifying party (80) is the same as said identity held by the identity provider (50).
