Effects of iterative block ciphers on quality of experience for Internet Protocol Security enabled voice over IP calls
<19> Analysis of the effects of encrypted VoIP streams on perceived Quality of Experience (QoE) from a user’s perspective is very important. Besides codecs, IP Security encryption of VoIP strongly relates to the payload sizes and this relationship has different effects on the overall QoE in terms of the way that users perceive the quality of a VoIP call. This paper investigates the facts that the default payload shipped with the codecs is not the optimal selection for an increased number of VoIP calls, especially when encryption is applied and a minimum level of QoE has to be maintained per call.
