Quantum cryptography is an emerging technology in which two parties may simultaneously generate shared, secret cryptographic key material using the transmission of quantum states of light. A unique aspect of quantum cryptography is that Heisenberg’s uncertainty principle ensures that if Eve attempts to intercept and measure Alice’s quantum transmissions, her …

Radio frequency (RF) technologies have limitations that cannot fulfill specific requirements. For instance, underground and underwater are challenging environments due to the absorption of high frequency electromagnetic (EM) waves in dense media. For hypersonic communications, Very Low Frequencies (VLF) band signals have large EM wavelengths that can penetrate the plasma …

Chinese military has been engaged in comprehensive modernization of  its air, naval, and ground forces, while incorporating a variety of anti-access/area denial (A2/AD) systems and capabilities.  “To operate against adversaries with “anti-access / area denial” capabilities the U.S. needs to disperse its forces, disaggregate its capabilities, confuse enemy sensors through …

Underwater communication is vital for undersea exploitation and modern communication. Conventional ways which employ acoustical technique for underwater communication have their drawbacks  including high path loss, narrow bandwidth, high bit error rate, among which unconditional security is more demanding due to commercial and secure interest.   Submarine communications have always been a challenge …

As warfighting has progressively become more sophisticated, involving larger forces, encompassing greater areas, and containing many new and more lethal weapon systems, the communication systems supporting the command and control functions have undergone a similar evolution. Communication methods have evolved to the capability of rapidly establishing worldwide “real time” communications …

Successful military operations depend upon freedom of action in the warfighting domains of air, space, ground, sea, and cyberspace. Today, effective command and control and situational awareness depend upon radio communications and sensors. Domination of the electromagnetic spectrum (EMS) enables joint force commanders to gain tactical, operational, and strategic advantage …

Whether in the field of battle, search-and-rescue or humanitarian aid efforts, the ability to share real-time, networked information between ground, sea and airborne forces is rapidly becoming the defining factor in a mission’s success. However modern  satellite and other  communications systems in higher frequecies are under constant threat from adversaries …

The vision for the future soldier is to be combat effective and also highly mobile, adaptive, networked, sustainable with total battle space situation awareness and information assurance. Therefore, he is equipped with night- vision goggles, radios, smartphones, GPS, infrared sights, a laptop as well as batteries to power them.   …

Unmanned Aerial Systems are gaining more importance every single day. Unmanned Aircraft Systems (UAS) are used for both defensive and offensive purposes. Different sizes and capabilities of UAS support a variety of different applications. Improved networking capabilities have enlarged the boundaries of UAS operations. Nations are working on more complex and …
