User identity management for permitting interworking of a bootstrapping architecture and a shared identity service

An apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus to perform at least the following:

• cause a request including a user identifier to be provided to a service provider;
• receive a re-direction including the user identifier, wherein the re-direction is to a shared identity service;
• cause, by the user equipment, an authentication request to be provided to the shared identity service shared among a plurality of service providers including the service provider in order to enable a shared identity service authentication, based on the user identifier;
• receive, at the user equipment in response to the causing the authentication request, the shared identity service authentication;
• establish a user session security key using at least a generic bootstrapping architecture;
• and
• establish a session with the service provider using the user session security key and the shared identity service authentication.

A computer program product comprising at least one non-transitory computer-readable storage medium having computer-executable program code instructions stored therein which when executed by at least one processor causes operations comprising:

• causing a request including a user identifier to be provided to a service provider;
• receiving, at a user equipment, a re-direction including the user identifier, wherein the re-direction is to a shared identity service;
• causing, by the user equipment, an authentication request to be provided to the shared identity service shared among a plurality of service providers including the service provider in order to enable a shared identity service authentication, based on the user identifier;
• receiving, at the user equipment in response to the causing the authentication request, the shared identity service authentication;
• establishing a user session security key using at least a generic bootstrapping architecture;
• and
• establishing a session with the service provider using the user session security key and the shared identity service authentication.
