A method, apparatus and/or computer program provides secure user authentication in a network having a dynamic set of services. The method comprises a client authenticating with an edge service and generating a query key. The edge service issues a request to the dynamic set of services. The request comprises (i) an encrypted identifier associated with the client, (ii) a private portion of the request being encrypted with the query key, and (iii) a public portion of the request. In response to ascertaining from the public portion of the request that it is able to respond to the request, one or more of the dynamic set of services respond to the edge service with (i) an identifier associated with the dynamic set of services, and (ii) the identifier associated with the client. The edge service then authenticates that it is able to respond to the request, including generating a session key. |
