Abstract
The Secure Communication Interoperability Protocol (SCIP) is the basic solution introduced by NATO for secure voice and data communication of different network devices through heterogenous networks. It was designed to provide interoperable end-to-end connectivity in a variety of communication systems, from military radio communication, traditional telephone communication system through satellite communication channels to VoIP and various types of mobile telephony standards. SCIP enables simplex operation in point-to-point or point-to-multipoint modes. It supports 2.4 kbps transmission to ensure communication via narrowband and broadband radio channels. The main challenge associated with this issue is therefore the provision of high security, high availability and high Quality of Service (QoS). The implementation of any encryption algorithm in nowadays heterogenous networks with restricted bandwidth can lead to degradation of the voice quality due to increased loss packets and packet latency resulting from the deterioration of radio channel conditions. This paper presents the results of measurements including the impact of end-to-end SCIP encryption on the quality of VoIP communication in a wideband radio channel. The measurements were carried out using the MultiDSLA tester and PESQ and POLQA methods. The results of laboratory tests indicate what effect does SCIP encryption-based security has on the voice communication quality over radio channel.
