Secure Communication Interoperability Protocol (SCIP) is a newly emerging application layer interoperability standard that is being developed for secure voice and voice band data communication between international coalition partners. It was designed to operate independently of the characteristics of underlying media layers. This paper will present the results of the first phase of an investigation into the performance of SCIP over a High Frequency radio link. A simulation using the Watterson model for HF propagation was created and is described. Voice quality performance data was gathered over a range RT configurations and channel conditions. The next phase of this investigation will examine the data communication performance of SCIP. The investigation will complete with actual on air testing of SCIP using the Harris RF5800-H High Frequency radio.
Michael T. Kurdziel is Sr. Managing Engineer, Secure Communications Products Group, for Harris Corporation. His area of technical expertise is secure communications systems design. This includes the design of encryption, key management and authentication systems and algorithms. Dr. Kurdziel is the principal algorithm architect for the MK-128 and MK-256 algorithms used in the CitadelTM and Citadel IITM Encryption Devices. The devices are Harris Corporation’s primary encryption solution for non-Type 1 applications. The algorithm designs have been critically reviewed by industry experts and have been found to have superior cryptographic strength. A paper on the CitadelTM and Citadel IITM architectures were presented to critical acclaim at the IEEE’s 1998 and 2004 MILCOM conferences, respectively. Dr. Kurdziel has been a member of Harris Corporation’s Communication Security Products technical staff since 1992. He holds Bachelor of Science (1986), Master of Science (1988) and Doctor of Philosophy (2001) Degrees in Electrical Engineering from the State University of New York at Buffalo. He holds three patents, has four patents pending and has been a licensed “Professional Engineer” (License No. 069432) in the State of New York since 1992.
