When using the web, long response times are bones of contention for users, i.e., they damp the Quality of Experience (QoE). Though, if one knows the cause of the long response time one may examine what could be done to eliminate the obstacle. In this paper, the authors determine the weak point of the Extensible Authentication Protocol Method for GSM Subscriber Identity Modules (EAP-SIM) with the OpenID service with regards to excessive authentication times, which determine the response times. In order to provoke controlled increases of the latter, they emulate bad network performance by introducing bi-directional delay between the supplicant (client) and the authentication server.
