Paper Abstract

One of the most important aspects in contemporary alliance and coalition communication is to ensure an adequate level of security for data and voice transmission. Continuous technological development is a factor that significantly hinders the development of the coalition standard aimed at protecting real-time data transmission (audio and video) in a reliable and safe way. For a long period of time, the coalition nations encountered problems connected with establishing a correct transmission between national systems. In order to achieve interoperability of communication systems, the United States government has made available and presented the standard FNBDT (Future Narrowband Digital Terminal) which in the course of time took the name SCIP (Secure Communication Interoperability Protocol). This protocol is being developed to this day by working groups consisting of representatives of scientific institutions and companies from the armed industry of NATO countries. Thanks to international cooperation the Protocol was adopted as standard STANAG 5068. It allows the use of cryptographic mechanisms to block the transmission of voice and data in a standardized way, ensuring interoperability of existing and newly formed allied and coalition communication systems for voice transmission. The SCIP protocol is based on two speech codecs: MELPe and G.729D. The article will discuss the current work carried out in NATO working groups on the definition of the COMSEC function and the way it is implemented in broadband radio stations to develop a broadband waveform for coalition activities. Also, the national waveform to secure communication in the broadband radio station will be presented. In the next chapter there will be the presentation of selected experimental results of broadband radio R-450C with the above-mentioned implemented mechanisms to protect voice communication. The obtained results will allow to evaluate the implemented mechanisms in terms of security. The developed analysis and obtained measurement results may be helpful both for people organizing radio communication using broadband radios as well as for those responsible for the proper operation of electronic warfare systems.
