TL;DR: The authors describe the projected role of LMSS secure voice in satisfying NCS national security and emergency preparedness requirements, and the issues remaining to be resolved before secure voice becomes an integral part of AMSC's services that are projected to commence in 1993.
Abstract: One of the responsibilities of the National Communications System is the incorporation of a secure telephone unit (STU-III)-based secure voice capability into the land mobile satellite service (LMSS) of the United States. As part of this effort, the NCS funds an effort at the Jet Propulsion Laboratory (JPL) to perform system studies, analyses, and field trials of prototype equipment. The first experiment involving STU-III's in a mobile satellite application was carried out by JPL in 1989 in Australia, using the Japanese experimental satellite ETS V. Subsequent work has included laboratory testing of recently developed STU-III interfaces, refinements to mobile satellite link characteristics simulation, and interaction on system architectural issues with the American Mobile Satellite Corporation (AMSC). The authors describe the projected role of LMSS secure voice in satisfying NCS national security and emergency preparedness requirements, and the issues remaining to be resolved before secure voice becomes an integral part of AMSC's services that are projected to commence in 1993. >

TL;DR: Inmarsat's land service enables users to create a virtual mobile and semi-fixed office or remote control room anywhere and instantly, and provides a range of voice, video and data applications with a reach that covers almost all of the world's land mass.
Abstract: Inmarsat, as the largest satellite communications provider for all mobile applications, has recently developed models for global business solutions (GBS), known as the Inmarsat-M4 system With the appropriate software and hardware, M4 service supports all mobile data and ISDN solutions up to 64 Kb/s, including a secure encryption (STU III/STE) system This service extends urban or mobile-based offices, such as a LAN, Internet and ISDN/PSTN, in rural locations using multimedia semi-fixed GAN (global area network) and BGAN (broadband GAN) portable and office applications Inmarsat's land service enables users to create a virtual mobile and semi-fixed office or remote control room anywhere and instantly It provides a range of voice, video and data applications with a reach that covers almost all of the world's land mass for governments, military, corporate, construction, agriculture, oil and mining, exploration, expeditions, newsgathering, SCADA monitoring and broadcasting, measurements and emergency associations in remote and rural environments

TL;DR: The progress being made in the North American wireless standards forums to define common solutions for interoperable data services, which include STU-III end-to-end secure voice and data modes as part of the commercial link offerings, is highlighted.
Abstract: The emergence of second and third generation commercial mobile telecommunications networks poses numerous technical challenges to maintain connectivity of existing COMSEC services, in particular STU-III (U.S. Government third generation secure terminal unit) services, for cellular and PCS users. This paper highlights the progress being made in the North American wireless standards forums to define common solutions for interoperable data services, which include STU-III end-to-end secure voice and data modes as part of the commercial link offerings. The issues associated with the evolution from analog to digital mobile networks and the implications for existing secure applications are discussed. We then point out the importance of the secure wireless activities as it is expected that PCS, digital cellular, and mobile satellite services will become part of the common infrastructures for COMSEC over commercial and military networks.

TL;DR: A simulation experiment is designed and conducted, demonstrating the feasibility of detecting such a proposed bearer option request under many environmental conditions.
Abstract: The U.S. Government is working with cellular/PCS standard bodies to develop bearer service option modes that will enable secure end-to-end digital voice between cellular handsets and existing STU-III (Secure Terminal Unit, 3rd generation) phones. A requirement is that handsets be able to reliably detect brief analog "go-secure" signaling sent by a STU-III as it attempts to transition from plain voice to encrypted voice mode, especially under conditions of fading errors. A simulation experiment is designed and conducted, demonstrating the feasibility of detecting such a proposed bearer option request under many environmental conditions.

TL;DR: The paper describes the design of an HF to wireline modem converter that plays the role of a radio-wireline interface (RWI) that acts as a gateway between tactical communications equipment and strategic communications equipment.
Abstract: The advent of personal communication systems (PCS) will provide global connectivity over commercial communication networks. Small, inexpensive, low-power terminals that are becoming available support this connectivity, provided that the user is reasonably close to a base station. Similar efforts are underway to provide extended connectivity to military users. The problems here are somewhat different because the communications often need to be end-to-end secure and because there often is no fixed infrastructure (base stations). The paper describes the design of an HF to wireline modem converter that plays the role of a radio-wireline interface (RWI). The RWI acts as a gateway between tactical communications equipment (for example, MINTERM) and strategic (STU III). >
