human intervention and decision-making is still needed to determine what specific data can and cannot be transferred. Accurate locational awareness is limited when maneuvering in areas where Global Positioning System (GPS) coverage is weak or non-existent. These areas include the inside of buildings, caves, etc. as well as built-up areas and urban canyons, which are also settings for many modern military operations. Much work on reliable fusion of positional data from multiple sensors remains to be done. Providing secure communications in network-centric warfare/network-centric operations is difficult, since successful key management for encryption is typically the most difficult aspect of cryptography, especially with mobile systems. The problem is exacerbated with the need for speedy deployment and nimble reconfiguration of military teams, to respond to rapidly changing conditions in the modern battlespace. International activities There is significant need to harmonize the technical and operational aspects of net-centric warfare and net-centric operations among multiple nations, in order to support coalition activities, joint operations, etc. The NATO Command Structure and many NATO and non-NATO nations have joined the Federated Mission Networking (FMN) initiative and work together under the FMN Framework Process to coordinate the design, development and delivery of operational and technical capabilities required to conduct net-centric operations. Within the Alliance the NATO Interoperability Standards and Profiles (NISP) provides the necessary guidance and technical components to support project implementations and Federated Mission Networking. Individual Standardization Agreements are the coordinating vehicle for establishing shared technical standards among NATO nations. See also Partnership for Peace for information on extending coordination efforts to non-NATO nations that are keen to support military operations other than war activities, such as international peacekeeping, disaster response, humanitarian aid, etc. Supporting comments "With less than half of the ground forces and two-thirds of the military aircraft used 12 years ago in Desert Storm, we have achieved a far more difficult objective. ... In Desert Storm, it usually took up to two days for target planners to get a photo of a target, confirm its coordinates, plan the mission, and deliver it to the bomber crew. Now we have near real-time imaging of targets with photos and coordinates transmitted by e-mail to aircraft already in flight. In Desert Storm, battalion, brigade, and division commanders had to rely on maps, grease pencils, and radio reports to track the movements of our forces. Today, our commanders have a real-time display of our armed forces on
